Vehicle Adaptation Guide


There are three categories of hand controls: primary, secondary and auxiliary. Primary controls are the essential controls that are required for driving and include the steering, accelerator, brakes and gears. Secondary controls operate the other functions of the vehicle which are required for safe driving such as indicators, park brake, hooter and wipers. The auxillary controls include the ‘comfort’ features of the car such as the radio and air conditioning. Driving controls can be either mechanical or power-supported via electronics, pneumatics or hydraulics.
