The Highway Code is the official road safety manual for the United Kingdom. It contains 278 numbered rules and 7 annexes covering pedestrians, animals, cyclists, motorcyclists and drivers. As well as the rules and annexes, there is information on road signs, road markings and vehicle markings. The annexes contain information on vehicle maintenance, licence requirements, documentation, penalties and vehicle security.

The first edition was published in 1931, with a price of one penny, and as of 2004 over one million copies of the modern code are sold each year.
