Autotests are one of the oldest disciplines in competitive motorsport in Ireland and is a real test of a wide range of driving skills. It is also one of the least expensive branches of motorsport. Each event consists of a number of tests (usually 10 or 12), that involve competitors carrying out a sequence of vehicular manoeuvres, as instructed in the test diagrams issued by the organisers. These manoeuvres include circling of pylons, "throwing" the car on the handbrake, crossing of lines and driving through slaloms, both forwards and reverse, in either first or reverse gears. Each driver is timed on each test and times are totalled to give results in each event. Whoever is quickest through the tests of the day is the winner.
