Section: iii Description: Guidelines Preamble Revised Date: January 18, 2012

GUIDELINES PREAMBLE

BACKGROUND

The National Mobility Equipment Dealer’s Association (NMEDA) was formed by mobility dealers to promote and support members who are engaged in providing vehicle modifications for people with disabilities. NMEDA, in supporting their membership, established these Guidelines to direct the mobility equipment industry toward consistency, quality and compliance. In keeping with NMEDA’s Bylaws and Mission, to ensure that vehicle adaptive equipment installed is always of high quality and that ethical business practices are followed, an industry Quality Assurance Program (QAP) was created. The NMEDA Guidelines are an integral part of this accreditation program, providing the best-known installation practices for the mobility equipment dealer.

PURPOSE

The National Mobility Equipment Dealers Association’s Guidelines are intended to guide and assist mobility equipment dealers in the completion of vehicle modifications for people with disabilities. The Guidelines are established to ensure that adaptive vehicle equipment is installed, and vehicle modifications are completed according to the highest level of industry standards and business practices. A mobility equipment dealer and installer shall use the Guidelines in conjunction with the equipment manufacturer installation instructions, Society of Automotive Engineers (SAE) recommended practices, the National Highway Traffic Safety Administration (NHTSA) safety standards and/or Transport Canada safety standards and practices and/or other applicable documents.

SCOPE

Consumers, installers, allied professionals, manufacturers, employers, researchers, policy makers and the public are urged to expect that vehicle modifications be completed in accordance with NMEDA Guidelines, manufacturer installation instructions, SAE recommended practices and applicable NHTSA/Transport Canada safety standards and practices. Application of these Guidelines requires judgment and an awareness of other applicable guidelines or regulations.  The NMEDA Guidelines may conflict with other laws, funding source guidelines or equipment manufacturer installation procedures. To ensure the best outcome for the consumer, in any situation, the more stringent requirement shall guide the modification process.

The NMEDA Guidelines are intended for use by the mobility equipment industry.  NMEDA Guidelines do not supersede Federal, State or Provincial laws and guidelines or mobility equipment manufacturers’ installation procedures; the more stringent will prevail.

IMPORTANT NOTE

This document has been developed based upon the most current information available at the time of this publication.  Information may change based on the latest vehicle models and mobility equipment available.  Please see the NMEDA website at www.nmeda.org for the most current updates.  Address any questions to the NMEDA office at 1-800- 833-0427.

Section: 1 Description: NHTSA and Exemptions to the Make Inoperative Prohibition Revised Date: July 27, 2022

1  NHTSA AND EXEMPTIONS TO THE MAKE INOPERATIVE PROHIBITION

PURPOSE

To present to NMEDA members information they may use to prepare the documentation needed to demonstrate compliance with U.S. government regulations when modifying vehicles for people with disabilities. This includes appropriate use of the exemptions to the Make Inoperative Prohibition, reference 49 CFR 595.7.

NHTSA prohibits companies from rendering inoperative vehicle features that affect the compliance of the vehicle to motor vehicle safety standards. Due to the nature of our business, the make inoperative prohibition has been amended to allow modifications of some vehicle components/systems covered by Federal Motor Vehicle Safety Standard (FMVSS). The exemptions are very specific and are not to be considered all-encompassing and they usually apply only to certain portions of the respective FMVSS. Penalties for failing to adhere to exemption are severe, up to and including civil liabilities.

Most modifications will require that a Make Inoperative Disclosure form be filled out and a label is affixed to the vehicle. There will be very few instances when a form is not required. REQUIREMENTS

1.1 Any motor vehicle repair business governed by U.S. law, that modifies motor vehicles to enable people with disabilities to operate, or ride in as a passenger and that intends to consider itself for the make inoperative exemption provided in 49 CFR 595.7 must provide the following information to:

National Highway Traffic Safety Administration 1200 New Jersey Ave., SE
Washington, D.C. 20590 (note that all submissions can be done on the NHTSA website: (https://vpic.nhtsa.dot.gov/mfrportal/)

  • Full individual, partnership, or corporate name of the motor vehicle repair business (modifier).
  • Residence address of the motor vehicle repair business and State of incorporation, if applicable.
  • A statement that the motor vehicle repair business modifies a motor vehicle to enable a person with a disability to operate, or ride as a passenger in, the motor vehicle and intends to take advantage of the exemption provided in 49 CFR 595.7.

1.2 Each motor vehicle repair business is required to submit the information under requirement (1.1) above shall submit the information not later than 30 days after it first modifies a motor vehicle to enable a person with a disability to operate, or ride as a passenger in, the motor vehicle. Each motor vehicle repair business who has submitted the required information shall keep its entry current, accurate and complete, by submitting revised information no later than 30 days after the relevant changes in the business occur.

1.3 In all cases where a company has modified a federal safety system, that could make the system inoperative, the Make Inoperative Disclosure form shall be filled out and one copy shall be given to the customer, and one retained in the vehicle file for 7 years, as stipulated by federal regulations.

1.4 All vehicles for which the make inoperative exemption is used as a basis for compliance shall have a permanent label (see Appendix D) affixed to the driver’s doorjamb that states: “This vehicle has been modified in accordance with 49 CFR 595.6 and may no longer comply with all Federal Motor Vehicle Safety Standards in effect at the time of its manufacture.” The label shall also include the Modifiers name and street address.

1.5 If the net result of the modifier or adaptive equipment company removing and installing equipment adds more than 220 lbs. (100 kg) to a vehicle, they shall notify the customer of the reduction in load carrying capacity of the vehicle after modifications are finalized. This notice shall also include whether or not the weight of the wheelchair is or is not included in calculating the new load carrying capacity.

1.6 If there is any uncertainty about whether a modification makes a federal safety standard inoperative, the modifier shall proceed with completion of the Make Inoperative Disclosure form and weight calculations.

1.7 REFERENCE: The Federal Motor Vehicle Safety Standards (FMVSS) and the specific exemptions NHTSA has permitted are detailed herein. Additionally, examples of those specific modifications or product installations that affect the specific safety standard may be provided.

FMVSS 101 CONTROLS AND DISPLAYS – This exemption permits controls to be operated by other means than the hand and/or foot. Products affecting this standard are any secondary control(s) no longer operated by the hand or foot. Ex: Power Headrests, Elbow Pads, Voice Activated Products. Controls that are added / relocated must, if possible and relevant, be identified as per FMVSS 101 and, if a new symbol is identified, it must be the color required and illuminated if required.

FMVSS 108 LAMPS, REFLECTIVE DEVICES AND ASSOCIATED EQUIPMENT – If it is not feasible to retain a vehicle’s turn signal self-cancelling device, it may be rendered inoperative by this exemption from S9.1.1 of 49 CFR 571.108 if the vehicle’s turn signal control must be modified or if the vehicle is modified so as to be driven without a steering wheel.

FMVSS 111 – REAR VISIBILITY – This part exempts the modifier from S5.5.1, S5.5.2, S6.2.1, and S6.2.2 of standard 111 in any case in which a personal mobility device transporter is temporarily installed on a vehicle by way of a trailer hitch to carry a personal mobility device (e.g., a wheelchair, powered wheelchair, or powered scooter) used by a driver or a passenger with a disability.

FMVSS 114 KEY LOCKING SYSTEM – This part exempts a modifier from S5.1.2 and S5.1.3 of 49 CFR 571.114, in any case where the original key locking system must be modified. This Standard was originally designed to prevent accidents due to theft and vehicle movement. Therefore, when modification to the ignition allows vehicle operation without physically inserting a key, it is strongly suggested to maintain the transmission interlock whenever feasible. Under this exemption, modifications to the vehicle’s key locking system do not require that the number of different combinations of the key locking system meet the requirements of the standard. The requirement that a warning device be activated when the key is left in the locking device and the driver’s door is opened is also exempted.

FMVSS 118 POWER OPERATED WINDOWS – In this part, any modifications to a vehicle where the power windows could be operated without a key in the ignition is exempt from S4 (a) of 49 CFR 571.118, in any case in which the medical condition of the person for whom the vehicle is modified necessitates the installation of a remote ignition switch to start the vehicle. A key is not required in the ON, Start or Accessory position for the power windows or roof panels to operate. The modifier shall, however, ensure that the vehicle electrical system is in the ON or Accessory position for the windows to operate.

FMVSS 123 – MOTORCYCLE CONTROLS AND DISPLAYS – In this part, any modifications to the primary or secondary controls of a motorcycle as well as the required supplemental engine stop control is exempt from
S5.1 and S5.2.1 of 49 CFR 571.123, in any case in which the modification necessitates the relocation of original equipment manufacturers controls. For further details, the vehicle is exempt from the following requirements: S5.1. Each motorcycle shall be equipped with a supplemental engine stop control, located and operable as specified in Table 1.
S5.2 Each motorcycle to which this standard applies shall meet the following requirements: 
S5.2.1 Control location and operation. If any item of equipment listed in Table 1, Column 1, is provided, the control for such item shall be located as specified in Column 2, and operable as specified in Column 3. Each control located on a right handlebar shall be operable by the operator’s right hand throughout its full range without removal of the operator’s right hand from the throttle. Each control located on a left handlebar shall be operable by the operator’s left hand throughout its full range without removal of the operator’s left hand from the handgrip. If a motorcycle with an automatic clutch is equipped utilizing a single control for front and rear brakes, the control shall be located and operable in the same manner as a rear brake control. With a supplemental rear brake control, the control shall be located on the left handlebar. If a motorcycle is equipped with self-proportioning or antilock braking devices.

FMVSS 135 PASSENGER CAR BRAKE SYSTEMS –
The vehicle is exempt from the requirement of S5.3.1 of 49 CFR 571.135 if the modification requires the removal of the original foot control. Also, the control of the parking brake is not required to be independent of the service brake control. The modifier may remove the brake pedal only if the situation requires it and all other options have been exhausted. For further details, S5.3.1. states that the service brakes shall be activated by means of a foot control. The control of the parking brake shall be independent of the service brake control, and may be either a hand or foot control.

FMVSS 201 OCCUPANT PROTECTION IN INTERIOR IMPACT – In this part the vehicle pillars on either side of a vertically stowed lift or ramp, as well as the side rail between these pillars are exempt from 49 CFR 571.201 in the case of a vehicle that does not have a lowered floor or raised roof. If the vehicle has a lowered floor or raised roof, all FMVSS 201U targets are exempt. All hand grips and vertical stanchion bars are exempt in all vehicles. Whenever possible energy absorbing materials should still be used to minimize the potential for injury. With respect to: (i) targets located on the right-side rail, the right B-pillar and the first right side ‘‘other’’ pillar adjacent to the stowed platform of a lift or ramp that stows vertically, inside the vehicle,
(ii) targets located on the left side rail, the left B-pillar and the first left side ‘‘other’’ pillar adjacent to the stowed platform of a lift or ramp that stows vertically, inside the vehicle,
(iii) targets located on the rear header and the rearmost pillars adjacent to the stowed platform of a lift or ramp that stows vertically, inside the vehicle,
(iv) targets located on any hand grip or vertical stanchion bar,
(v) all of S6 of 571.201 in any case in which the disability necessitates raising the roof or door, or lowering the floor of the vehicle, are exempt.

FMVSS 202, 202(a) HEAD RESTRAINTS – This part permits vehicles to be modified to allow wheelchair bound occupants to ride in or operate a vehicle without having headrests. This part also exempts the front driver’s headrest from the height and width requirements, and it exempts the front passenger headrest from the height requirements. The provision further allows the modifier to install alternative headrests or alter original headrests to accommodate the disabled user in the front passenger seat.

FMVSS 203 IMPACT PROTECTION FOR THE DRIVER FROM THE STEERING CONTROL SYSTEM – This exemption from S5.1 of 49 CFR 571.203 permits driving aids to be attached to the steering wheel despite the fact that there may be a problem with entanglement of loose clothing. The exemption includes any driving or steering aids, any modifications to the steering column, column extension, air bag removal, etc. The exemption also applies to the steering wheel impact requirements allowing the replacement or relocation of a steering wheel in any case in which the modification necessitates a structural change to, or removal of, the original equipment manufacturer steering shaft. Except as provided in the exemption the steering control system of any vehicle to which this standard applies shall be impacted in accordance with S5.1 (a).

FMVSS 204 STEERING CONTROL REARWARD DISPLACEMENT– This exemption from 49 CFR 571.204 steering wheel displacement loads is for a vehicle steering shaft that is modified for steering wheel extensions or specialized steering systems or in any case where the modification necessitates a structural change to, or removal of, the original equipment manufacturer steering shaft.

FMVSS 208 OCCUPANT CRASH PROTECTION– This exemption permits modifiers to remove and/or deactivate all airbags for the front row designated seating position modifications, provided Type 2 or Type 2A seat belts meeting the requirements of 49 CFR 571.209 and 571.210 are installed at that position. Modifications include any hand controls and any position for people riding in a wheelchair.

FMVSS 207 and 214 HEAD RESTRAINTS, SEATING SYSTEMS, AND SIDE-IMPACT PROTECTION – These exemptions are for wheelchairs and wheelchair securement systems (tie downs), allowing the removal of the driver’s seat. Vehicles designed for individuals who drive from their wheelchair do not require a driver’s seat or a headrest (see exemption for 202) and vehicles modified for those who ride in a wheelchair do not require a headrest. These standards address certified seating and side impact protection. It is imperative that the modifier make every effort to create a safe environment for the securement of the wheelchair and the customer.

FMVSS 216 – ROOF CRUSH RESISTANCE – This part exempts the vehicle in any case in which: (i) The disability necessitates raising the roof; and, (ii) The vehicle, after modification, meets 49 CFR 571.220.

FMVSS 225 – CHILD RESTRAINT ANCHORAGE SYSTEMS – This exemption allows the removal of a child restraint system if necessary, to accommodate a person with a disability, as long as there is at least one compliant tether anchor in a rear row seating position of the vehicle. If there are no rear row seats the child restraint anchorage system must be installed in the front row passenger seat. Note: If there are airbags in the front row passenger side that are not automatically deactivated by the vehicle, the air bag should be deactivated if possible.

FMVSS 226 EJECTION MITIGATION – This exemption from S4.2 and S5 of 49 CFR 571.226, Ejection mitigation, is for the side of the vehicle where a seat on that side of the vehicle must be changed to accommodate a person with a disability.

1.8 Other Points to Consider:

  • Air Bags and Supplemental Restraint Systems: In any instance where a retrofit air bag ON-OFF switch is available and the individual with a disability can operate the switch, the company shall install this system instead of simply disconnecting the airbag. In all instances, a compliant lap AND shoulder belt shall be provided. If no switch is available, a permanent disconnect of the airbag is permissible for clients who have a recognized disability.
  • People of short stature having no other disability shall continue to submit written requests to NHTSA under the same format as previously required.
  • Safety standards not exempt: Some safety standards could be affected by mobility products or modifications when NO Exemptions have been given. If a vehicle modification affects one of the following standards, proper documentation for demonstrating compliance shall be completed.
  • FMVSS/CMVSS 102 – TRANSMISSION LEVER SEQUENCE, STARTER INTERLOCK, TRANSMISSION BRAKING EFFECT – No exemption given. The operation of the transmission into Park, Reverse, Drive, shall remain in the OEM sequence.
  • FMVSS/CMVSS 103 & 104 – WINDSHIELD DEFROSTING AND DEFOGGING, WINDSHIELD WIPING AND WASHING – No exemption given. Vehicle modifications shall not prevent the driver from operating the necessary controls for function of the front and rear windshield defrosting or operation of windshield wipers.
  • FMVSS/CMVSS 105 – HYDRAULIC BRAKE SYSTEMS – No exemption given.
  • FMVSS/CMVSS 113 – HOOD LATCH SYSTEM – No exemption given.
  • FMVSS/CMVSS 124 – ACCELERATOR CONTROL SYSTEMS –– No exemption given. Requires that throttle returns to idle position under stipulated conditions when all force is withdrawn. All electronic (Drive by Wire) throttle control products shall have a monitoring system to prevent unwanted acceleration in the event of an electronic malfunction or in the event of a severance or disconnection in the accelerator control system. This includes all servo gas and brake products.
  • FMVSS/CMVSS 206 – DOOR LOCKS AND DOOR RETENTION COMPONENTS – No exemption given. Modifications are required to maintain all OEM latching mechanisms or other compliant mechanisms. This standard includes power doors and rear folding ramp systems.
  • FMVSS/CMVSS 209 – SEAT BELT ASSEMBLIES – No exemption given. All seatbelt assemblies shall be tested, certified and labeled to this standard. Sewing belts together at the dealer level is not allowed.
  • FMVSS/CMVSS 210 – SEAT BELT ANCHORAGES – No exemption given. Modified seat belt anchorages shall be installed and tested according to the standard and installed according to the manufacturer of the component.
  • FMVSS/CMVSS 301 FUEL SYSTEM INTEGRITY – No exemption given. All modified vehicles shall be tested and certified by the alterer to meet this standard. Only lowered floor/fuel systems that have been tested and certified can be used as kits by the alterer. Documentation shall be on file.
  • FMVSS/CMVSS 302 – FLAMMABILITY OF INTERIOR MATERIALS – No exemption given. All materials used in completing a vehicle modification including carpet, wall material, and headliner material shall meet this standard. Information shall be on file showing certification.

Section: 2 Description: Client/Vehicle Assessment Documentation Revised Date: November 3, 2021

2  CLIENT/VEHICLE ASSESSMENT DOCUMENTATION

PURPOSE

To outline the client/vehicle assessment process and define the documentation that is required to be collected prior to the installation of automotive adaptive equipment or vehicle modifications for drivers and occupants with disabilities.

SCOPE

The NMEDA Guidelines are intended for use by the mobility equipment industry.  NMEDA Guidelines do not supersede Federal, State or Provincial laws and guidelines or mobility equipment manufacturers’ installation procedures.  In cases where there are conflicting guidelines or procedures, the more stringent will prevail.

REQUIREMENTS

General:

2.1     The client shall be seen in person by the installing dealer for a client/vehicle assessment.

2.2     The client/vehicle assessment should consider the following (as applicable):

      • How the vehicle will be used and who will routinely be traveling in the vehicle
      • The combined weight of all portable mobility equipment or other objects that will routinely be loaded into or placed on the vehicle (this is the anticipated cargo weight)
      • The size of the client and
      • overall combined weight of all occupants that will routinely be traveling in the vehicle (this is the anticipated occupant weight)
      • The placement/location of each occupant andany portable cargo
      • Make/model and dimensions/weight of any wheelchair(s)/scooter(s) that will routinely be transported,
      • Seated heights of any wheelchair/scooter user(s) routinely traveling in the vehicle

2.3      Using all the information gathered during the assessment, the dealer shall make determinations on the adequacy of the equipment to be installed and whether or not it is appropriate for the vehicle and the client. The determinations should also include:

      • if the modification will allow the client (and his/her family) safe entry/egress from the vehicle
      • if the combined post-modification curb weight and the anticipated payload weight (the anticipated cargo weight plus the anticipated occupant weight) would cause any of the GVWR, GAWR (front or rear), or the TWR ratings to routinely be exceeded.

If the proposed modifications are not appropriate for the client, or will not allow safe client access, or will routinely overload the vehicle or exceed any of the weight ratings, the vehicle should not be modified.

2.4     If the modifications are being made to a client supplied vehicle. The client’s vehicle shall be inspected by a mobility equipment dealer or professional evaluator prior to the installation of any adaptive equipment or vehicle modifications. The inspection and approval for the modifications to be made should be conducted with the knowledge of the type and level of modifications being considered for the client.  Equipment shall not be installed by anyone other than a qualified mobility equipment dealer.

2.5     If the adaptive equipment being installed requires adjustments to custom fit to the client, the client shall be present for a final fitting to ensure that the equipment is properly installed and operable by the client. This is often done, and sometimes required to be done by, or in the presence of the driver rehabilitation specialist (DRS).

2.6     In addition, for clients using primary driving equipment, there are two documents that are required to be retained and kept on file:

2.6.1     A driver’s license – the dealer shall ensure that the client has a current and valid driver license.

2.6.2     And one of the following:

a. An assessment report from a qualified driver rehabilitation specialist that includes specifications for equipment, modifications, and training; or,

b. A statement of current experience in operating the equipment to be installed. NMEDA standard form QAP-F04 “Statement of Customer Experience” can be used for this requirement.

NOTE: Driver license systems and restrictions codes vary widely from jurisdiction to jurisdiction.  The mobility equipment dealer shall obtain and become familiar with the driver license requirements and restriction for their clients.

2.7     If a client is considering changing or replacing their primary driving equipment with a type that has different functional characteristics (i.e. changing from a push/right-angle hand control to a push/twist control), an updated assessment report shall be obtained from a qualified driver rehabilitation specialist.

NOTE: Certified driver rehabilitation specialists (CDRS) are NMEDA’s strongly recommended first choice to meet the above minimum requirements.  NMEDA recommends behind the wheel driver instruction and training.  NMEDA requires that the client be given operational orientation of the installed equipment.  NMEDA recommends behind the wheel instruction if the client is new to adaptive driving controls or their skills or equipment have changed.

 

For more information about a CDRS, visit ADED, the Association for Driver Rehabilitation Specialists at www.aded.net.

3.19 When a mobility equipment manufacturer does not supply a designated ground wire but relies on using mounting bolts for a ground source, the installer shall be sure that proper care has been taken to remove any undercoating, paint, padding or carpet that could limit the conductive ground (negative) path. Installing an independent ground strap from unit’s motor to closest vehicle body panel will ensure continuous ground source.  Note:  Be sure the movement or motion of mobility equipment does not interfere with either power or ground cables.  An added ground strap, installed from the negative terminal of the battery to the body of the vehicle or from the starter to the chassis of the vehicle will be installed when any type of electrically powered mobility equipment is installed.  The gauge of the ground cable shall be the same or larger than the power cable supplied by the mobility equipment manufacturer. The cable will be a multi-strand copper automotive type product.  Please consult OEM procedures.  Refer to Section 6.5 for details on an additional ground strap.

3.20 NMEDA QAP dealers shall have all the equipment and tools necessary to comply with the manufacturer’s installation instructions. The equipment type/model used shall be capable (appropriate range, precision, and unit of measure) for the readings and/or specification given in the instructions or standard. As a minimum, the dealer shall have the following equipment at each location:

  • Calibrated Four-Corner scales
  • Multi-meter[1] (used for continuity and electrical measurements, ohms and volts)
  • Floor jack and jack stands, or vehicle hoist
  • Crimping tools of appropriate type for connectors used in the shop
  • Air compressor and air tools or appropriate corded/cordless tools
  • Calibrated Torque wrench(s)1 – if the multi-meter is used for any quantitative acceptance data, it must be calibrated**

3.21 Labeling Requirements:

Manufacturers (includes final stage manufacturers) – must label their vehicle production in accordance with applicable regulations, including the Code of Federal Regulations (CFR), Motor Vehicle Safety Act (Canada), Federal Motor Vehicle Safety Standards (FMVSS) and Canada Motor Vehicle Safety Standards (CMVSS), in the required locations on the vehicle.

3.22 Shipping Loose Equipment

NMEDA dealers are required to install all adaptive equipment that they sell or must meet the following requirements if they are shipping uninstalled (loose shipped) adaptive equipment for a consumer.

  • The customer must be made aware that some adaptive equipment is being shipped loose and that someone other than the selling dealer will be installing the adaptive equipment
  • The selling dealer must make arrangements with another properly accredited NMEDA dealer to install the loose shipped equipment. Such arrangements must be on file.
  • The selling dealer must verify that the requirements of 3.1 and 3.2 are being met.
  • The installing technician has the proper current certification from the manufacturer of the loose shipped equipment.
  • Documentation must be maintained in the customer file indicating who installed the loose shipped equipment.
  • Loose shipped equipment must be shipped directly to the installing dealer.
  • The vehicle must be labeled when the equipment is installed.

3.23  Installing Used Equipment

There is no prohibition to install used equipment. However, extreme caution should be exercised. The installer should be able to verify the product history for that equipment and be certain the equipment was properly maintained and is not damaged in any way. When the product history cannot be verified or when there is any uncertainty in the quality or functional status of the equipment, the equipment should be declared suitable for reinstallation by the equipment manufacturer prior to installation. In all cases, the equipment shall be verified by a certified technician to meet original functionality. Used equipment must be in good working order and free of any defects. Used equipment shall not be used if prohibited by the manufacturer, third-party payer, or DRS prescription. Many manufacturers prohibit equipment from being reused if it has been in an accident or under certain other conditions. Always consult with the equipment manufacturer prior to installing used equipment if there is any question about warranty or reuse. The customer shall be made aware and approve all cases where used equipment is installed. A used equipment inspection is required for all used equipment installations. The installer should consult with the equipment manufacturer to help determine appropriate inspection steps if the inspections will be performed by the installer. Objective evidence that a used equipment inspection was completed is required. Anytime used equipment is installed it shall be noted on the work order and label reporting form.

Installing used equipment that was manufactured prior to a new or amended safety standard effective date, into a newer vehicle, could make inoperative a federal standard, especially where the modifier is not aware of changes to a federal standard since the used equipment was manufactured. The equipment shall be in compliance with the F/CMVSS standards in effect at the time of manufacture.

Example:
A used lift that was manufactured before the FMVSS 403/404 amendment was enacted in 2005 can be installed in a newer vehicle without making inoperative a federal standard. However, a used lift that was manufactured after 2005 must be in compliance with  FMVSS 403/404.

[1] If the multi-meter is used for any quantitative acceptance data, it must be calibrated.

Section: 4 Description: Service Practices Revised Date: February 23, 2022

4  SERVICE PRACTICES

PURPOSE

To outline the expected minimum service practices of all NMEDA dealers selling or servicing modified vehicles or adaptive equipment to / for customers or end-users. These service practices apply to all NMEDA dealers selling or servicing modified vehicles or adaptive equipment to / for customers or end-users.

REQUIREMENTS

4.1 Service Responsiveness:

It is a required practice for all NMEDA dealers to provide customers with 24 hour, seven-day-a-week service response.  NMEDA dealers are expected to have a system in place which allows customers easy access to an after-hours answering service, or service telephone number, or service beeper number.  Subsequently, NMEDA dealers are expected to respond to a service call promptly, and provide emergency assistance as warranted.  It is highly recommended for the dealer to outline their response system in writing, maintained with the dealers other standard operating procedures.

The after-hours service person responding is expected to:

  1. Respond within 30 minutes to a service call.
  2. Verify that the situation is not life threatening.
  3. Confirm whether or not the problem is related to the conversion.
  4. Attempt to talk the customer through a corrective action/emergency backup procedure.
  5. Confirm that the customer has completed the necessary corrective action and can safely get to his/her destination, and advise the customer to call again with any other problems.

NOTE: If the customer cannot complete the corrective action, the dealer is expected to advise the customer that a service person will be dispatched.

If an after-hours service person must be dispatched for a road call:

  1. The service person is to confirm that the customer is in a safe location, and confirm any directions needed to find the customer.
  2. The service person is to inform the customer that the emergency service will likely be a temporary repair, intended only to get the customer safely to their destination. Therefore, a subsequent service appointment must be scheduled during normal service hours.
  3. The service person shall confirm the approximate arrival time.
  4. The service person shall confirm the approximate cost of the service call (if the service is not covered under warranty).

4.2 Service Personnel Qualifications:

Personnel designated by a NMEDA dealer to service and repair mobility equipment are to be knowledgeable of and certified by the manufacturer on the particular equipment to be installed, serviced, or repaired.  The servicing NMEDA dealer shall have service personnel certified to repair the level of equipment the dealer sells to the customer.  Exceptions such as temporary repairs intended to get the customer to safety until permanent repairs can be made as described in 4.1 are allowable when not avoidable.

4.3 Practices for Providing Before-Sales Services:

The purchase of a vehicle adapted for use by an individual with a disability without the individual first familiarizing themselves in-person with the vehicle and its equipment introduces many potential issues and risks.  Since these modified vehicles usually have a level of custom components for safe and optimum usability, it is vital that the customer/end user familiarize and interact with these components and equipment prior to committing to purchasing them.

Early in the sales process the NMEDA dealer should provide all customers with a copy of the most current NMEDA-endorsed consumer reference guide or website for selecting and purchasing adaptive vehicles and equipment so that they can become informed about the process and factors involved in selecting and purchasing adaptive vehicles and equipment and selecting the dealer to provide the equipment and service.

Note:  Reference Section 2: Consumer Documentation Sub-Sections 2.1 and 2.3 for relevant Before-Sale recommendations, also reference section 4.5.2.

4.4 Practices for Providing Pre-Delivery Services:

Once adaptive equipment prescription, specifications, and sales terms between the NMEDA dealer and customer and/or funding party are agreed upon, the adaptive modification process can begin.  Prior to delivery of the adapted vehicle, and depending on the complexity of the modifications package, “mid-conversion” and “final” fittings are an expected service component of the successful sale.  Of special note for drivers using adaptive equipment, a mid-conversion and final fitting with the end user or client present is expected to occur at the dealer location to fine tune equipment adjustments, determine tie-down locations, torso belt dimensions, etc. (refer to section 2.2).  Furthermore, in such situations it is strongly recommended for a Driver Rehabilitation Specialist, whenever available, to be actively involved on site in the fitting process to assure the end user can safely and effectively use the equipment.

Note: The dealer shall provide as much notice as possible when scheduling these fittings.

BACK TO TOP

4.5 Practices for Providing After-Delivery Services:

4.5.1 After-Sale Service Dealer Agreements:

Out of NMEDA’s commitment to the overall high-quality experience and outcome of the customer with a disability, NMEDA requires that all dealers who sell vehicles equipped with mobility products ensure that the customer is provided service after the sale.

A service area is defined as an area within 100 miles (160 km) or 2 hours drive time (whichever is shorter in the best judgment of the selling accredited location) from which a location can reasonably service customers to the level of service expected of a QAP compliant location. The definition of this proximity is for the purpose of providing customers who purchase a vehicle, adaptive equipment, or both, with a reasonable distance to travel for repairs. The servicing QAP accredited location is required to have technicians certified to service the mobility products installed by the selling accredited location. Refer to the QAP Rules for exceptions.

4.5.2 Misrepresentation of After-Sale Service Availability:

Without first establishing written service agreements between dealers, no NMEDA member shall state or imply to a client or potential customer that following a sale, ANY NMEDA MEMBER can or will provide service to the vehicle or adaptive equipment package.

4.5.3 After-Sale Equipment Use Training and Demonstration:

It is required that the NMEDA dealer will demonstrate the proper use and maintenance of the equipment to the end user/operator of the mobility equipment. This demonstration and training shall include the proper fit and use of any included wheelchair tie-down systems and wheelchair passenger restraint systems (refer to www.travelsafer.org). Furthermore, it is highly recommended to allow the end user/operator to demonstrate their competency in the use of all systems sold or provided by the dealer.

4.5.4 After-Sale Documentation

4.5.4.1 Vehicle Acceptance Documentation:

A modified vehicle is required to have a set of delivery documents completed and a vehicle delivery or acceptance document signed by the client and mobility equipment dealer prior to the vehicle being released to the client. Components of the vehicle acceptance documentation:

    • Customer contact information;
    • Final vehicle and adaptive equipment inspection;
    • Final client fitting;
    • Vehicle test drive;
    • Customer and other users’ in-service training;
    • Customer acceptance;
    • Conditions of vehicle release;
    • Customer has been informed that additional insurance covering adaptive equipment is generally recommended and may be required
4.5.4.2 Other Documentation:

Additionally, it is required for the NMEDA dealer to provide at a minimum the following documentation to the customer or end user no later than the final delivery of the modified vehicle or installed mobility equipment:

    • The original operation/owner’s/warranty manuals for each item of installed equipment that is not included in the vehicle operator’s manual.
    • Dealer is to retain an electrical circuit diagram and wire routing, in schematic format.  Can be supplied to customer if requested.
    • A preventative maintenance schedule detailing required maintenance for all installed equipment.
    • The selling, installing, or repairing NMEDA dealer’s written warranty detailing all items covered with parts and labor components separately addressed as applicable for the customer to clearly understand what is and is not included.
    • Original copies of any manufacturer’s warranties. The NMEDA dealer is required to register all warranties with equipment manufacturers.  A signed privacy statement may be required.
    • Per 49 CFR 595, a list of the FMVSS or portions thereof with which the vehicle may no longer be in compliance and the vehicle’s new load carrying capacity if modifications have reduced the load carrying capacity by more than 220 pounds (100 kg).  Dealer must state whether the weight of the user’s wheelchair is included in the available load carrying capacity.  NMEDA dealer must retain a copy for 7 years.  Applies to members governed by US law.

Section: 5 Description: Vehicle Weight Analysis Revised Date: July 28, 2021

5  VEHICLE WEIGHT ANALYSIS

PURPOSE

When modifying vehicles for people with disabilities, special care shall be given to the weight of the added equipment and the effect it could have on the vehicle’s driving characteristics.  Adding equipment can cause the available load carrying capacity to be compromised, or the GVWR (Gross Vehicle Weight Rating), either of the GAWR (Gross Axle Weight Rating) or the TWR (Tongue Weight Rating) to be exceeded. If any of these weight ratings are compromised, the vehicle’s safe driving characteristics can be adversely affected causing premature system failures as well as braking and steering functionality that could result in catastrophic failure. Applies to all vehicles sold that contain mobility equipment or that are modified with mobility equipment or components.

Definition: (See Appendix C)

REQUIREMENTS

5.1 All vehicles shall be assessed prior to any modifications to determine if the vehicle’s GVWR, GAWR, and TWR (as applicable) will not be exceeded and the available load carrying capacity is sufficient to accommodate the anticipated payload when in normal use.

Note: Reference the Weight Analysis Process Flowchart document (QAP-F30) and the Weight Analysis best practice instruction sheet (QAP-117) for more detailed information and assistance. These documents can be found on the NMEDA website document center.

5.2 A four-corner weight analysis shall be performed and documented when the lesser of 1.5% of GVWR or 100 lbs. (45 kg) or more of net weight is added to a vehicle after modification.

5.3 Exceeding a vehicle’s GVWR, GAWR, or TWR is prohibited by Federal Law.

5.4 Upon completion of modification, a vehicle’s available load carrying capacity must not be less than Designated Seating Positions (DSP) times 150 lbs. (68 kg). For the purpose of determining load carrying capacity, occupied wheelchair tie down positions are counted as DSPs and 150 lbs. must be allotted for the wheelchair occupant and the weight of the wheelchair is considered as cargo**. A modified vehicle with insufficient load carrying capacity shall not be delivered. (**Not applicable to define the Seating Capacity on Tire placard in Canada.)

5.5 The Remaining Cargo Capacity is measured by taking the Load Carrying Capacity after modification and deducting the required occupant weight capacity (DSP times 150 lbs). The Remaining Cargo Capacity can never be less than zero.

5.6 It is the customer’s responsibility to safely load the vehicle. In circumstances where the customer has additional cargo (including mobility devices) that could overload the vehicle when all designated seating positions are occupied the dealer shall provide guidance on how to safely load the vehicle. The combined weight of occupants and cargo should never exceed the load carrying capacity of the vehicle.

5.7 According to 49 CFR Part 595: If the load carrying capacity of the vehicle after modification is reduced by 220 lbs (100 kg) or more the reduction in load carrying capacity shall be disclosed to the customer. When providing this information, the dealer must state whether the weight of the user’s wheelchair is or is not included in the available load capacity. The Make Inoperative disclosure form may be used for this purpose. Refer to Section 1 for more information. Applies only to members governed by US Law.

5.8 When installing rear mounted scooter and wheelchair lifting or carrying devices, the tongue weight rating (TWR) shall not be exceeded. Modifying or adding a hitch receiver is prohibited unless endorsed by information found in sources such as the owner’s manual, incomplete vehicle document, dealer bulletin, or, if the vehicle is obviously equipped with an OEM trailer towing package. In most cases the vehicle manufacturer specifies the towing capacity, which determines the tongue weight rating. Manufacturer warranties and/or compliance with F/CMVSS 301 “fuel system integrity” rear impact crash test can be voided if OEM hitch receivers are modified or aftermarket hitch receivers are added.

5.9 If a modification adds the lesser of one and one half percent (1.5%) of the vehicle’s GVWR or 100 pounds (45 kg) in additional weight, the reduction in load carrying capacity must be determined and a Load Carrying Capacity Reduced label stating the amount of weight the load capacity has been reduced from the original is to be affixed to the vehicle within 1” of the existing Tire Placard (label). The purpose of this is to record the cumulative effects of adding numerous pieces of equipment to a vehicle over time.

5.10 It is strongly recommended that the consumer be advised of the load carrying capacity of the vehicle after modification to assure the consumer’s safety.

Section: 41 Description: Hybrid / Electric Vehicle Revised Date: November 28, 2018

41  HYBRID / ELECTRIC VEHICLE

PURPOSE

To provide guidelines when modifying or installing mobility equipment in hybrid or all electric vehicles. This section does not include instructions or guidelines for structural modifications.

Definitions:

Based on the foundation of SAE J1715 “Hybrid Electric Vehicle (HEV) and Electric Vehicle (EV) Terminology”

Hybrid – A vehicle equipped with two or more energy storage systems, both of which must provide propulsion power either independently or together. Typically, one of these energy storage systems powers an internal combustion power-plant.

Electric– A vehicle whose power-plant is solely powered by an electrochemical energy storage system(s). There are a wide variety of storage systems and charging systems.

SAFETY PRECAUTIONS:

Hybrid and Electric vehicle systems are very different from traditional Internal Combustion vehicles and have many variations. Before any accessory is added or service is performed to these systems, an understanding of the vehicle’s power-plant and vehicle OEM service guidance is strongly encouraged. Vehicle OEM or recognized service training classes from SAE or ASE are recommended BEFORE attempting any propulsion or controls modifications. Working with hybrid and electric vehicles may require changes in the normal operation of the Dealer Service/Installation in such things as new dangers that shops had not experienced:

41.1 Safety training is a key to safely servicing or modifying the vehicle.

41.2 Moving a hybrid vehicle or EV around the shop environment is significantly quieter and much more dangerous to those working in the environment. In comparison the standard IC engine currently makes significant noise, so team members may not hear an EV or hybrid being moved. Electric vehicles are silent when operated, so there’s a risk that people would be unaware of planned or unexpected movements.

41.3 Electric vehicles may also move unexpectedly on their own unless the Power Propulsion Key is removed.

41.4 The battery location on the vehicle may require new lifting methods for the batteries and may require communicating with the component/vehicle manufacturer.

41.5 High voltage components and cables are capable of delivering a fatal electric shock. Some Hybrid and electric vehicles have energy storage systems in excess of 650 volts, anything over 150 volts can cause serious injury and or death.

41.6 Electric vehicles and hybrid vehicles have uniquely stored electrical energy with the potential to cause explosion or fire. Explosive gases and harmful liquids can be released if batteries are damaged, overcharged or incorrectly modified.

41.7 Components can hold a dangerous voltage even when vehicles are “off”. It is critical to find the Power Propulsion Key on the vehicle and remove this before any work is started.

41.8 Caution should be exercised for unexpected movement of electric motors or the vehicle itself, due to stored magnetic forces within the vehicle and its systems.

41.9 High-voltage batteries can be heavy, bulky and awkward to handle components, several times heavier than conventional batteries, so lifting aids and devices may be required to prevent musculoskeletal disorders.

41.10 Hybrid vehicles can start their internal combustion engine automatically when the ignition is on and the vehicle detects that the battery has discharged to a level at which recharging is necessary.

41.11 High electric currents in batteries and high-voltage systems in electric vehicles can cause magnetic fields, which can induce eddy currents in the human body. Risks arising from electromagnetic fields are, therefore, potentially dangerous for mechanics and others with active implants such as cardiac pacemakers.

41.12 Hybrid and electric vehicles often take advantage of low rolling resistant tires and energy efficient systems that have different operational guidance that installers and service technicians trained on more traditional vehicles may not be familiar with.

REQUIREMENTS

41.13     Charging Systems:

A wide variety of charging systems and energy storage systems are involved with little industry standardization. No modification to these systems should be performed unless at the explicit direction of the manufacture who has supplied all needed parts and guidance.

41.14     Backup and Accessory Power Systems:

Many hybrids and electric vehicles run all the accessory functions and many secondary controls off of a 12 volt or 24 volt auxiliary power system. Many of these auxiliary systems are sized only for these operations. These are often found in non- traditional locations in the vehicle. The equipment manufacture should supply information if drawing power from these systems is appropriate and the installer should follow all the guidelines.  Care must be taken to verify that circuit breaker and or fuse protection to the system are appropriately labeled and to train the end users as to location and operation.

INSTALLATION CONCERNS:

41.15 Follow the vehicle and equipment manufacturers explicit installation instructions for the make and model of the vehicle. Due to the large variants in vehicle design, if the manufacturer’s instructions do not cover the vehicle type and model, contact the manufacturer for guidance.

41.16 Special Care is needed when working around the propulsion systems not to compromise the integrity. Doing so can cause severe property damage, injury or death. This is especially true when drilling into blind areas of the vehicle.

WEIGHT DISTRIBUTION [INC. LOAD CARRYING CAPACITY]:

41.17 Weight distribution is more critical in a hybrid or electric vehicle due to the unique energy reclamation systems using the brakes. Hybrids and electric vehicles often take advantage of regenerative braking to do most of the stopping, which also replenishes the energy storage system. An out of balance vehicle can affect the handling controls and stability of the vehicle as well as have unintended consequences when “braking”.

41.18 Following the Vehicle OEM listed weight distribution guidelines is critical.

41.19 Training the end users about weight distribution requirements when carrying their mobility equipment is very important.

HIGH VOLTAGE VS. LOW VOLTAGE SYSTEMS:

41.20 Any system that is over 60Vdc up to and including 1500 Volts is considered HIGH VOLTAGE. No modification to a high voltage system should be performed.

41.21 48-volt vehicle systems are considered “Mild Hybrids”.

41.22 Systems under 40 Volts are considered Low Voltage Systems.

F/CMVSS 305 [Electric-powered vehicles: electrolyte spillage and electrical shock protection]:

41.23 There is no exemption under the 49 CFR Part 595 “Make Inoperative Exemptions” for Federal Motor Vehicle Safety Standard (F/CMVSS) 305, so no installation or service may modify any part of the vehicle safety system specified under F/CMVSS 305.
