Recording requirements before comparing used wheelchair-accessible vehicles

The short answer

Write down your requirements before you open any listings. That means measuring the wheelchair with the user seated in it, deciding who will ride where and how they will board, and recording where the vehicle will actually be parked and loaded. Then collect the same identity and conversion documents for every candidate vehicle. Send both sets of information to a qualified mobility professional, and have the actual vehicle, the actual wheelchair and the intended user assessed together before you commit. A completed worksheet does not prove a vehicle is suitable. Its job is to make every candidate comparable and to make sure the right questions get asked.

A wheelchair-accessible vehicle (WAV) is a car, minivan or van that has been modified, or converted, so a person can enter and ride while seated in a wheelchair. Common modifications include a lowered floor, a ramp or lift, a kneeling feature that lowers the vehicle at the entry point, and a securement system that holds the wheelchair in place while the vehicle moves. On a used WAV, the conversion matters as much as the base vehicle. Two vehicles with the same year, make and model can have very different access, equipment and service histories.

Two meanings of electric

People searching for electric wheelchair-accessible vehicles usually mean one of two things. Some need a vehicle for a powered wheelchair. Others want a converted vehicle built on a battery-electric base. Both can apply to the same purchase.

Powered wheelchairs are often larger and heavier than manual chairs, and they usually cannot be folded and stowed. Record the chair exactly as it is used, including any seating system, headrest, joystick mount and other accessories. Ask how each candidate's ramp or lift and securement system are rated for the occupied chair.

If the base vehicle is battery-electric, add charging access at home to your worksheet. Ask the conversion provider how the conversion was carried out on that platform, because many electric vehicles carry their battery pack under the floor. Floor-lowering is a common conversion method, so this question matters.

Part 1: Record the wheelchair and the user

Measure the configuration that will actually travel, not the chair's catalog specifications. Record the numbers as measured and leave the judgment about whether they fit a given vehicle to the professional assessment.

• Wheelchair make, model and type (manual or powered)
• Current configuration: seating system, cushion, headrest, footrests, armrests, trays, joystick or attendant controls
• Overall width at the widest point, as configured
• Overall length, including footrests and anything that projects to the front or rear
• Seated height of the occupant, measured from the ground to the top of the head, and the height of any headrest if it is taller
• Any tilt, recline or elevating functions used during travel, and whether the occupant rides in a tilted or reclined position
• Date of measurement and the name of the person who measured
• Known upcoming changes, such as a new chair, a new seating system or growth in a child user, so measurements can be repeated

Part 2: Record occupants, seating and assistance

• Will the wheelchair user ride as a passenger, or drive from the wheelchair or from a transfer seat?
• Preferred wheelchair position: front passenger area, driver position, or rear or middle of the cabin
• Number of other regular occupants and their seating needs, including child seats
• Whether the wheelchair user needs to be within reach or sight of another occupant during travel
• Who will operate the ramp or lift and fasten the securement: the user, a caregiver or a driver
• Any physical limits on the person assisting, such as difficulty bending, kneeling or reaching into the floor area
• Cargo that must travel at the same time, such as medical equipment, a second mobility device or shopping

If the wheelchair user intends to drive, the assessment usually involves a driver rehabilitation specialist in addition to the vehicle review. Record that intention clearly, because it changes which professionals need to be involved and which vehicles are worth considering.

Part 3: Record access and boarding locations

Entry direction is often the first real fork in a WAV search. Side-entry conversions load through a side door, and rear-entry conversions load through the back. Neither is better in general. The right choice depends on where the vehicle will be loaded and where the wheelchair user needs to sit.

Consideration	Side entry	Rear entry
Space needed to board	Clear space beside the vehicle for the ramp and wheelchair approach	Clear space behind the vehicle for the ramp and wheelchair approach
Typical seating position	Often allows the wheelchair user to sit toward the front, which matters for drivers and front passengers	Commonly places the wheelchair user in the rear or middle of the cabin
Parking situations to record	Narrow parking spaces, curbs on the boarding side, garage walls beside the vehicle	Parallel parking with vehicles behind, garages with little rear clearance, sloped driveways
What to confirm on each candidate	Which side the ramp deploys from, and any impact on front seating	Whether the rear seating that remains meets your occupant count

• Preferred entry direction and the reason, such as wanting to ride in front or having limited side clearance at home
• Each regular boarding location: home garage, driveway, street, workplace, school, medical appointments
• Measured clear space at each location beside and behind where the vehicle would stop, with the date and the name of the person who measured
• Garage door opening height and interior ceiling height if the vehicle will be garaged
• Obstacles: curbs, slopes, gravel, posts, walls, overhead structures
• Photographs of each location, labeled with what they show

Part 4: Record each candidate vehicle the same way

Listings for used WAVs describe vehicles inconsistently. One seller lists the ramp type, another lists only the base vehicle. Use the same record for every candidate. Write unknown rather than guessing what equipment is installed.

• Vehicle identity: VIN, model year, make, model, trim, odometer reading and the seller
• Base powertrain: gasoline, hybrid or battery-electric
• Conversion provider, and the conversion date if documented
• Conversion type: lowered floor, raised roof or other structural changes
• Entry direction and access equipment: in-floor ramp, fold-out ramp or lift, and whether it is powered or manual
• Kneeling feature, if fitted
• Wheelchair securement type, such as manual tie-downs or a docking system, and the occupant restraint provided
• Serial numbers or other identifiers for the ramp, lift, securement and any driving controls
• Documents available: conversion paperwork, operation manuals for the access equipment, service and maintenance records for the conversion, and any warranty information
• Recall status for the base vehicle and for the conversion equipment
• Records requested from the seller but not yet received, and the date of each request

In the United States, open recalls on the base vehicle can be checked by VIN through the federal recall lookup that NHTSA provides. Conversion equipment may be covered separately by the converter or the equipment manufacturer, so ask the seller for equipment recall information as well.

Questions to send about each candidate

• Who carried out the conversion, and is the conversion documentation available?
• What are the rated capacity and usable dimensions of the ramp or lift, according to its manufacturer documentation?
• What are the door opening height and interior height along the path the wheelchair takes to its riding position?
• What securement and occupant restraint system is installed, and what standard or testing does its documentation reference?
• Has the access equipment been serviced, and by whom? Are the records available?
• Are there any open recalls on the vehicle or the conversion equipment?
• Is any conversion or equipment warranty still in effect, and does it transfer to a new owner?
• Has the vehicle been in a collision or had structural repairs affecting the converted floor or entry area?
• Can the vehicle be inspected and tested with the actual wheelchair and user before purchase?

Review sequence before choosing

• 1. Complete Parts 1 to 3 once, and update them if the wheelchair, user or boarding locations change.
• 2. Complete Part 4 for each candidate, then send the seller questions and log what comes back.
• 3. Send the requirements worksheet and each candidate's documents to an appropriately qualified mobility professional, such as an occupational therapist, a mobility equipment dealer or a driver rehabilitation specialist if the user will drive.
• 4. Arrange an in-person assessment involving the actual vehicle, the actual wheelchair in its travel configuration and the intended user.
• 5. For each candidate, record every question raised, the document that answered it, who reviewed it and any items still unresolved.
• 6. Move a candidate forward only after the individual requirements and all outstanding questions have been reviewed. Drop or pause candidates whose records cannot be obtained.

Here is an illustrative example. A family records that the powered chair user needs to ride beside the driver and that their only parking space is a narrow garage bay. Those two facts point their search toward side-entry candidates and put garage side clearance at the top of the review questions. They still need an assessment with the chair in the vehicle before any candidate can be treated as suitable.
