The aim of autotesting is to drive around a set of markers adhering to a set route in as short a time as possible. The route is set out in a test diagram and involves competitors using both forward and reverse gears. They are required to cross lines, stop astride lines, park in "garages", perform spin turns, handbrake turns and reverse flick turns. Penalties are given for striking markers, line faults or incorrect manoeuvres. The competitor with the fastest time and the least penalties is the winner. Autotesting is an inherently safe and inexpensive form of motor sport. Speeds are not very high because competitors normally only use forward and reverse gears. Driving skill is the key to success. The lower risks for drivers results in lower costs as helmets and fire protection clothing are not required. A variety of vehicles can be used from production road going cars that are taxed, insured and have a valid MOT Certificate through to one off "specials".
