What Is a WC19 Wheelchair? How NEMT Drivers Spot and Secure One

What WC19 means

WC19 is Section 19 of RESNA’s American National Standard for wheelchairs, Volume 4, Wheelchairs and Transportation. Its title is Wheelchairs Used as Seats in Motor Vehicles. A chair that fully meets it is called a WC19 wheelchair. The latest edition of the volume dates from 2017, and RESNA’s standards committee says it is revising it as of September 2026. The comparable international standard is ISO 7176-19.

RESNA, the Rehabilitation Engineering and Assistive Technology Society of North America, publishes three related sections:

Section	Common name	What it covers
18	WC18	Wheelchair tiedowns and occupant restraint systems, the straps and belts in your van. See WTORS and WC18 tiedowns.
19	WC19	The wheelchair itself, used as a seat in a motor vehicle
20	WC20	Seating systems mounted on a WC19 frame, so a custom seat keeps the chair crashworthy

WC19 is voluntary. It is an industry standard, not a federal or state rule. The University of Michigan Transportation Research Institute explains (August 2023) that the WC19 version of a chair is called the “transit option,” an add-on to the basic chair, and that therapists must justify it to the payer case by case.

What a WC19 chair must do

RESNA’s position paper on WC19 lists what the standard requires. Each item makes your driver’s job easier.

WC19 requirement	What it means on the ride
Four clearly marked securement points on the front and back of the frame, or more for very heavy chairs, shaped to take hooks and straps	You know exactly where each tiedown goes
Points placed so a driver can attach each hook with one hand while reaching from the side, with clear strap paths to typical floor anchors	Faster securement, less reaching into the rider’s space
Passes a 30 mph, 20 g frontal sled test secured by a four-point strap tiedown, with a crash dummy sized to the chair’s user weight	The frame holds its shape in a frontal crash
Crash-ready lap belt anchor points on both sides, just below and behind where the seat meets the back	The rider has the option of a lap belt anchored to the chair
Rated acceptable or better for fitting a vehicle-anchored lap and shoulder belt	The lap belt sits low on the pelvis without threading it through gaps in the chair
Discloses how far the seat moves sideways in a 45-degree tilt test	You know how stable the chair is in turns
No sharp edges on rigid parts	Straps and belts are not cut in a crash
Batteries and motors stay attached in the crash test, and batteries are gel-cell or sealed	No battery breaking loose or leaking acid

A U.S. Access Board briefing of September 22, 2021 sums it up: WC19 chairs are designed to keep their form, stay upright with the belted rider seated, and keep their battery under the 20 g forces of a 30 mph frontal crash.

How to spot a WC19 wheelchair

Check these at the curb, before you load the rider:

1. The label. WC19 chairs are labeled with words or a circular logo showing they meet the standard.
2. Hook symbols. The four securement points are clearly marked with a hook symbol, two at the front and two at the back.
3. A lap belt on the chair. Newer WC19 chairs offer a crash-tested lap belt anchored to the frame, labeled as complying with WC19.
4. Ask. The rider, a caregiver, or the owner’s manual can confirm it. Ask at intake too, so dispatch knows before the van arrives.

Brackets without the hook symbol are not proof. If you cannot confirm the chair is WC19, secure it as a chair without WC19.

A custom seat can change the answer. WC19 testing covers the chair with the seat its maker chose. WC20 lets a seat from another company be crash-tested on its own, so a WC19 frame with a WC20 seat stays crashworthy, RESNA’s position paper explains.

Securing a WC19 chair compared with other chairs

RESNA notes that most wheelchairs in use are not yet WC19, so drivers must know both methods. The steps below follow the University of Michigan’s Ride Safe guide (2018).

Step	WC19 chair	Chair without WC19
Direction	Forward-facing	Forward-facing
Where the hooks go	The four marked securement points	Welded frame joints, or frame parts joined with hardened steel bolts, often marked by six raised lines on the bolt head, as close to the seat as possible
Never hook to	Anything but the marked points	Armrests, footrests, wheels, or any adjustable, moving, or removable part
Strap paths	Run each strap on the clear path the chair is designed to give from its marked point to a floor anchor	Anchor rear straps directly behind the rear points, at 30 to 45 degrees from the floor, and front straps wider than the chair
Tilt-in-space chairs	Use the marked points	Hook all four straps to the seat frame or all four to the base, never a mix
Lap belt	The chair’s WC19-labeled lap belt, or the van’s lap belt low on the pelvis	The van’s lap belt low across the pelvis, at 45 to 75 degrees when seen from the side, routed between the armrest and back if needed
Shoulder belt	Across the middle of the shoulder and chest, attached to the lap belt near the hip	The same
Postural belts	Never a substitute for the lap and shoulder belt	Never a substitute

Tighten every strap to remove all slack. Clamp-type securement devices are not recommended, because they do not hold chairs well in frontal crash tests. The Ride Safe guide also says it is best to ride with the backrest reclined 30 degrees or less from vertical. For the full securement routine, use the wheelchair securement guide and the wheelchair securement checklist.

What the rules require of you

The federal ADA rules apply to every chair, WC19 or not, as in force in September 2026:

• Use the system. You must use your securement system and may require the rider to let you secure the chair (49 CFR 37.165).
• Do not refuse the ride. You may not deny a ride because the chair cannot be secured to your satisfaction.
• Offer, never force, a transfer. You may recommend that a rider move to a vehicle seat, but you may not require it. The Ride Safe guide says transferring to a vehicle seat is generally safest when it is feasible.
• Meet the securement limits. On vans rated under 30,000 pounds, the system must hold up to 2,500 pounds per leg and at least 5,000 pounds per chair, and limit movement to 2 inches in any direction in normal driving when the chair is secured by the maker’s instructions (49 CFR 38.23(d)).

The Access Board notes it has no authority to set standards for wheelchairs, which is why the ADA rule speaks only to your van. Brokers add training: MTM Health’s Virginia handbook, approved August 10, 2026, requires wheelchair securement training before a driver transports wheelchair riders.

Putting it to work in dispatch

Ask one question at intake: “Is the wheelchair crash-tested, with hook symbols on the frame?” Write the answer in the rider’s profile with the chair type, manual or power, and whether it tilts. Then the driver arrives knowing which securement method to use, and a wheelchair accessible vehicle with the right kit is on the schedule.
