Traffic signals ahead
A red triangle with a vertical traffic light symbol warns that the road ahead has traffic lights. Used where the lights might not be visible from a distance — on bends, just after a hill crest, or following a tree-lined stretch. Cover your brake and prepare to stop if the lights change.
