Warning signs

Triangles warn. A red-bordered triangle warns of a hazard ahead, such as a bend, a junction, a crossing or a steep hill, so you have time to slow down and look. The picture inside tells you what the hazard is. Tap any sign below for the full detail, or take the road signs short test.
