Minimum speed limits
The vast majority of roads in the UK do not have minimum speed limits enforced. Those that do utilize a blue circular road sign that differs from circular signs with a red ring signifying the maximum speed limit. Minimum speed limits are imposed to maintain a steady continuous flow of traffic. See minimum speed limits and driving too slow for further information.
Traffic calming measures are seen more frequently on UK roads. Road narrowing on one, or both sides is a technique often employed to slow traffic in residential areas. Priority through the narrowing is often controlled by signs and road markings. The circular sign is informing drivers they must give way to oncoming traffic and the blue sign is informing drivers that they have priority.
Cycle lane signs
Road signs for cyclists and cycle lanes are mostly blue, although blue signs may be accompanied with a directional white road sign. The driving theory test involves answering questions on many road signs including signs for cyclists and cycle lanes.
Bus lane signs
Bus lanes signs are blue and are accompanied with road markings. The times that bus lanes are in operation may or may not be show on the sign. It is illegal to drive in a bus lane within its operational times. If no times are visible, assume the bus lane is in operation 24 hour a day. Bus lanes can usually be used by buses, taxis and cyclists in times of operation. For further information, see bus lane signs and bus stops, plus bus lane road markings.
Blue motorway signs
Most motorway signs are blue and although currently learner drivers cannot legally drive on motorways, the law may change to allow the use of motorways to learner drivers. Motorway signs and signals are however used as part of the multiple choice question categories within the driving theory test. See motorways for an in depth guide on motorway rules, reflective studs, signs, signals and rules.
