Warning signs
Traffic signals ahead
What it means
Traffic lights are coming up that you cannot see yet, usually hidden by a bend, a crest, a bridge or a queue. Ease off the accelerator and get ready to stop, and start reading the brake lights of the cars in front. Do not speed up hoping to catch a green you cannot even see.
Highway Code Rule 146 — read it on GOV.UK
