Handicapped drivers can choose between mechanical and electronic controls depending on their preferences. Drivers also choose between fixed and portable controls. Push/rock hand controls are the most popular, according to Superior Van & Mobility. This system uses a vertical grip installed on the left or right side of the steering wheel. The driver pushes the handle towards himself to accelerate and away towards the dashboard to brake.

Some drivers choose the push/twist hand control that resembles the controls on a motorcycle. The system uses a mechanical grip installed horizontally on the side of the steering wheel. To accelerate, the driver twists the grip like a motorcycle's throttle. To brake, the operator pushes the grip towards the dashboard.

Apart from the modifications on the braking and accelerating functions, hand-control cars are similar to other cars. Car dealers modify these cars according to the disability and preferences of the driver. Drivers of regular cars can also use hand-control cars.
