As of 2015, vehicle modifications available for disabled people include siren detectors that warn hearing-impaired drivers of approaching emergency vehicles by detecting the high-decibel sound waves their sirens emit, as well as adjustable steering knobs or joysticks that allow one-handed vehicle control. Other modifications include quad forks, palm grips and v-grips on steering wheels to accommodate quadriplegic drivers, and pedal extenders to increase the heights of accelerators and brakes, allowing drivers to control them by hand rather than by foot.
Vehicle modifications such as electric gear changers allow drivers to switch gears with the left hand. Wheelchair storage carriers mounted on the back or roof of a vehicle can save storage space and eliminate the need for a van instead of a car. Drivers who use scooters and wheelchairs can have lifts installed on their vehicles to make it easy for them to enter and exit the vehicles. Many vehicle manufacturers offer reimbursements and rebates for disability-related adaptive modifications.
Individuals preparing for adapted driving should undergo an evaluation by assessment professionals who provide prescriptions for obtaining or modifying motor vehicles to meet their specific needs. The evaluation is especially important for disabled people who have never driven or those who have not driven since they became disabled. People who have experienced an accident, disease or illness that has resulted in an overall change in their physical ability should also undergo an evaluation to determine what type of vehicles and adaptive tools they need.
