Road Signs


Regulatory signs

(other than those for low bridges, railway and tramway level crossings, bus and pedal cycle facilities and road works)

Most regulatory signs are circular. A RED RING or RED CIRCLE indicates a prohibition. A BLUE CIRCLE generally gives a positive(mandatory) instruction or indicates a route for use only by particular classes of vehicle (see sections on tram signs and bus and cycle signs).

Two notable exceptions are:

The "STOP" sign and road markings: you must stop before crossing the transverse line on the road and ensure the way is clear before entering the major road.

The "GIVE WAY" sign and road markings: you must give way to traffic on the major road (the upright sign or both the sign and the triangle on the road might not be used at junctions where there is relatively little traffic).

No entry for vehicular traffic, including pedal cycles (usually indicates the end of a one-way road where all traffic is travelling in the other direction) No vehicles except pedal cycles being pushed by hand Alternative plates used with the "no vehicles" sign, indicating times when vehicles are prohibited, except for access
