The common form of hand controls consists of a push-pull handle mounted below and projecting to the side of the steering wheel housing.
One exception is the GuidoSimplex Semi-Automatic Syncro Drive Clutch System[2] along with an over/under ring accelerator[3] and hand controlled brake, a car with a manual gearbox can be adapted.
More complex fittings may also connect into the electronic circuitry of the vehicle to place indicator and other switches in easy reach of the driver without requiring them to release the hand controls or steering knob.
Extension levers or adapted grips may also be fitted to the parking brake to allow it to be applied by a driver with limited hand or arm strength.
[9] If a UK-based employee with a disability requires an adapted car for work use, this would potentially be considered grounds for a "reasonable adjustment" by the employer in accordance with the Equality Act 2010.
In this case the responsibility for funding the adaptation would either lie with the employer or potentially be covered by the government-operated Access to Work scheme.
[11] Several designs of portable push-pull hand-controls are also available which may be quickly connected to a new vehicle by screwing clamps to the pedals, however these may not be suitable for drivers with more extensive requirements.
