Roadcraft
Roadcraft refers to the system of car or motorcycle control outlined in two books "Roadcraft: The Police Driver's Handbook" and "Motorcycle Roadcraft: The Police Rider's Handbook". The books are produced by the Police Foundation and published by Her Majesty's Stationery Office (HMSO). Overview. Roadcraft is the UK's police handbook that outlines a system of car and motorcycle control split into five phases represented by the acronym IPSGA: The taking, using and giving of Information is, arguably, most important and surrounds (and drives) the five phases IPSGA. It may, and often should, be re-applied at  any phase in the System. The System is used whenever a hazard requires a manoeuvre. A hazard is something which requires a change in speed, direction or both. The benefit of applying a systematic approach to driving is to reduce the simultaneous demands on the vehicle, the driver mentally and the driver physically. That is, the System seeks to separate out the phases of a manoeuvre into a logical sequence so that the vehicle and the driver avoid being overwhelmed by having to do too much at the same time. For example, braking and steering at the same time place  greater demands on the vehicle's available grip and in the worst case can lead to a skid. Whilst the books were originally put together at the Metropolitan Police Driving School at Hendon, and intended for police drivers and riders, they have been available for sale to the general public since the mid-1950s. Civilian advanced driving organisations such as RoSPA and the Institute of Advanced Motorists base their teaching and advanced motoring tests on Roadcraft.
