Roads in The United Kingdom - Signage

Signage

Signage on the UK network conforms broadly to European norms, though a number of signs are unique to Britain and direction signs omit European route numbers. All length distances are shown in miles or yards, speed is in miles per hour whilst height and width restrictions are required to be shown in feet and inches (though the metric measurements may optionally also appear). Until recently the government was obliged to convert all signs to metric under a commitment made at the time of the UK's accession to the European Economic Community. The European Commission has now abandoned that requirement.

The signage system currently in use was developed in the late 1950s and the early 1960s by the Anderson Committee, which established the motorway signing system, and by the Worboys Committee, which reformed signing for existing all-purpose (non-motorway) roads. It was introduced in 1965 and is governed by the Traffic Signs Regulations and General Directions. Signs may be of an informative, warning or instructional nature. Instructional signs are generally circular, warnings are triangular and informative signs are rectangular or square. Motorway informative signs use white text on a blue background, primary routes are indicated by green directional and distance signs with yellow text, whilst secondary roads use black text on a white background.
