Automobile access is challenging for many people with mobility impairments.
Access to standard vehicles for wheelchair users is often problematic. However, many adaptations are available for automobile drivers and passengers with disabilities. Ramps or lifts can be added to mini-vans or full-sized vans to help individuals enter and exit the vehicle. Seats and restraints can be modified to help individuals safely access the driver's seat. Driving adaptations that can be added to help people with disabilities drive independently include horizontal, foot, lever, and zero-effort steering;zero effort brakes;vacuum brake and gas systems; and power steering backup. Individuals with disabilities usually arrange for a specialized driver evaluation, administered by a qualified professional, during which vehicle modifications and adaptive equipment are recommended.
