GUIDELINES PREAMBLE     back to top
________________________________________

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 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.

1 NHTSA AND EXEMPTION TO THE MAKE INOPERATIVE PROHIBITION
Revised December 15, 2009    back to top
________________________________________

Purpose
To present to NMEDA members information they shall use to prepare the documentation needed to demonstrate compliance with Government regulations when modifying vehicles for people with disabilities. This includes appropriate use of the Exemption to the Make Inoperative Prohibition, reference 49 CFR 595.7.

Scope
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 FMVSS. The exemptions are very specific and are not to be considered all encompassing and usually apply only to certain portions of the respective FMVSS standard. Penalties for failing to adhere to exemption are severe, up to and including civil liabilities.

NOTE:  Most modifications will need to have a Make Inoperative form filled out and a label affixed to the vehicle. There will be very few instances when a form is not required.

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

Administrator
National Highway Traffic Safety Administration,
400 Seventh Street, SW.
Washington, DC 20590.

• 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.
• Applies to members governed by US law.

1.2  Each motor vehicle repair business required to submit information under requirement (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 safety system, that could make the system inoperative, the "Make Inoperative" form shall be filled out and one copy shall be given to the customer, and one retained in the permanent vehicle file for 5 years. This is a federal regulation. This form shall be incorporated with the payload statement.

1.4 All vehicles for which the make-inoperative exemption is used as a basis for compliance shall have a permanent label affixed to the driver's doorjamb that states:
"This vehicle had 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 original manufacture".    (The label shall also include the Modifiers name and street address.)

1.5  If the modifier or adaptive equipment company adds more than 220 lbs. to a vehicle, they shall notify the customer what the payload capacity of the vehicle is after modifications. This notice shall also include the statement that these calculations do or do not include the weight of the wheelchair and the new payload capacity shall be written on the "Make Inoperative" form.

IMPORTANT:  It is the Vehicle Modifier's responsibility to ensure that the vehicle payload capacity after modifications have been completed is sufficient to allow for 150 lbs of Capacity per seating position including wheelchair tie-down positions. If the vehicle payload capacity is not sufficient to bear the number of seating positions without exceeding the vehicle GVWR, provisions shall be made to eliminate any number of seating positions necessary to comply. (Removal of seatbelts is not an acceptable method of eliminating a seating position.) An overweight vehicle cannot be delievered to the customer.

An overweight vehicle cannot be delivered to the customer.

1.6  If there is any uncertainty about whether a modification makes a Safety Standard inoperative, the Modifier shall proceed with completion of the form(s) and weight calculations. The modifier shall indicate any reduction in the load carrying capacity of the vehicle if it has been reduced by more than 220 pounds.

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 are explained.

• FMVSS 101 - CONTROLS AND DISPLAYS - 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 the FMVSS 101 and, if a new symbol is identified, it must be the color required and illuminated if required.(Except for S5.2 (a), S5.3.1, S5.3.2, and S5.3.5 of that section.)

Purpose
To outline the proper consumer documentation required prior to the installation of adaptive driving equipment or vehicle modifications -or- recommending and installing equipment and modifications for passengers using wheelchairs and scooters.

Scope
The NMEDA Guidelines are intended for use by the mobility equipment industry.  NMEDA Guidelines do not supersede Federal, State Laws or Provincial law 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  Prior to recommending or installing any adaptive driving equipment, the mobility equipment dealer shall require documentation that the devices/equipment is appropriate for the client.  The documentation should reflect the client's current functional status.  Documentation should be in the form of an assessment report that includes equipment and modification specifications and/or a properly restricted and current driver license.

NOTE:  Driver licensing systems and restrictions vary widely from state to state.  The mobility equipment dealer should obtain and become familiar with the driver license requirements and restrictions for their clients.  A convenient link to these agencies is:  www.thedsaa.org

2.2  The client shall be seen in person by the installing dealer for a proper transportation assessment.
 
2.3  Prior to recommending or installing modifications for a transport vehicle for a wheelchair/scooter user, the mobility equipment dealer shall obtain the following documentation:

1. Make and model of wheelchair/scooter
2. Dimensions/weight of wheelchair/scooter
3. Accessories (head rests, ventilators, tilt systems, etc.)
4. Seated height of the user
5. Client weight

2.4  The client's vehicle shall be inspected by a mobility equipment dealer or professional evaluator prior to the installation of any adaptive driving equipment or vehicle modifications.  The inspection and approval for the modifications 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 The client shall be present for a final fitting and adjustments to insure that the equipment is properly installed and operable by the intended user(s).

Drivers:
2.6  The mobility equipment dealer shall ensure that the user has a current driver license and a copy shall be placed in their file.

4 RECOMMENDED SERVICE PRACTICES
Revised August 24, 2005    back to top
________________________________________
           
Purpose
To outline the expected minimum service recommended practices of all NMEDA dealers selling or servicing modified vehicles or adaptive equipment to / for customers or end-users.

Scope
These recommended 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 recommended 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 dealer's 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 their 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.  The servicing NMEDA dealer  shall have service personnel certified to repair the level of equipment the dealer sells to the customer.

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 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 4.5.2 below.

4.4  Recommended 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. (reference 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.

4.5  Recommended 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 the disability, NMEDA strongly recommends that all dealers who sell vehicles equipped with mobility products ensure the following condition is met for their customers:

All vehicles outfitted with mobility products for use by individuals with disabilities should be sold and delivered only in the selling dealer's service area, or in mutual agreement with another NMEDA dealer who will serve the client.  This mutual agreement should be evidenced by a completed "Service Dealer Agreement" (See Appendix B), which is to be signed by the NMEDA selling dealer, the NMEDA servicing dealer, and the customer prior to finalizing a sale of the vehicle.  An acceptable alternative would be for dealers to establish service centers with qualified service personnel that are located or available on reasonably short notice to provide service or repairs within service facilities that are located within comfortable traveling distance of the customer.

A service area is defined as an area within which a NMEDA dealer can reasonably service customers to the level of service expected of NMEDA dealers with the expectation that the customer will drive back to the selling dealer for service and repairs.  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 NMEDA dealer is expected to be certified to repair the level of equipment sold to the customer.

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 acceptance document signed by the client, mobility equipment dealer, driver rehabilitation specialist and/or third party payer prior to the vehicle being released to the client. Recommended 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.

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 understandwhat 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.  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 5 years.  Applies to members governed by US law.

5 VEHICLE WEIGHT RATINGS
Revised August 24, 2005    back to top
________________________________________

Purpose
Any vehicle receiving adaptive equipment or modification shall not compromise OEM vehicle weight specifications.

Scope
When modifying vehicles for people with disabilities, special care shall be given to the weight of the added equipment and the affect on the vehicles driving characteristics.  Not only could added equipment cause an overage of GVWR (Gross Vehicle Weight Rating), it can also exceed a GAWR (Gross Axle Weight Rating) without compromising payload guidelines.  A vehicle's safe driving characteristics can be adversely affected causing premature system failures as well as braking and steering functionality can be compromised.

Definition: (See Adaptive Equipment Transportation Industry Terminology)

Requirements
5.1  All vehicles shall be assessed prior to any modifications to determine if the vehicle's
GVWR, GAWR are adequate for the modifications and load carrying capacity.  A four-corner weight analysis shall be performed and documented when 220 lbs or more is added to a vehicle.

5.2  Exceeding a vehicle GVWR or GAWR is prohibited.

5.3  Upon completion of modification, a vehicle's load carrying capacity shall allow for the availability of 150 lbs per seating position including wheelchair tie-down positions and for the weight of the mobility aid.  Customer requests to modify a vehicle that will not accommodate a proper load carrying capacity shall be denied.

5.4  According to 49 CFR 595: If a modification adds more than 220 lbs to a vehicle, reduction in the load carrying capacity shall be disclosed to the customer via the Make Inoperative Provision.  Dealer must state whether the weight of the user’s wheelchair is included in the available load carrying capacity.  Reference Guideline 1 for more information.  Applies to members governed by US Law.

5.5  When installing rear mounted scooter and wheelchair lifting or carrying devices, tongue weight rating (TWR) shall not be exceeded.  Modifying hitch receivers for outside carriers is prohibited.

NOTE: In most cases the OEM specifies the towing capacity which determines the tongue weight rating.  Manufacturer warranties can be voided when suspension modifications and special built hitches are added.

5.6  If a modification adds more than one and one half percent (1.5 %) of the vehicle’s GVWR in additional weight, the reduction in load carrying capacity must be determined and a Reduced Load Carrying Capacity Label stating the revised load capacity 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.

  31 ELECTRONIC VEHICLE INTERFACE
  NMEDA Classification: High Tech
  Revised December 20, 2007    back to top
  ________________________________________

  Purpose
  There have been many changes to OEM vehicles in the last few years which may have led to increased complexity in vehicles' electrical systems.  Multiplex wiring in many newer vehicles has one wire carrying signals to several different modules (e.g. door locks, power windows, etc.).  These modules interpret the information carried on the wires to activate devices.  Tapping into these wires can affect the signals going to and from the modules causing malfunctions.  These changes have introduced the likelihood of damaging OEM electronics by making what, in the past, were minor changes or additions to the electrical system.  It is increasingly incumbent upon dealers not to cut, modify, or attach anything to the OEM electrical system unless they have detailed, up to date information about any impact those changes could make.
   
  Scope
  Depending upon the year, make and model of the vehicle to be worked on, modifications or interfacing to the electrical system beyond the positive and negative terminals of the battery could cause damage to the OEM system.
   
  Examples of items that can cause problems when improperly installed:

  Definition: (See Adaptive Equipment Transportation Industry Terminology)
