Warning signs

A warning sign is a traffic sign that alerts drivers to a potential danger or change in road conditions ahead, giving them enough time to slow down and react safely. These signs warn about hazards such as sharp bends, pedestrian crossings, slippery surfaces, merging traffic, animals on the road, or upcoming intersections. Their purpose is not to forbid or command anything, but simply to prepare drivers for situations that require extra attention.

How should I react to a pedestrian warning in the United Kingdom?

Reduce speed, look along both sides of the road and be ready to stop. The warning identifies a pedestrian hazard ahead; children, people with limited mobility or others may enter the road unexpectedly.

Does a traffic-lights-ahead warning require an immediate stop in the United Kingdom?

No. A warning sign is not an automatic STOP instruction and does not create a new numerical speed limit. Reduce speed when necessary, look for a queue or a concealed signal, and obey the traffic lights and any separate speed or stop signs.
