Warning signs
These signs warn you of hazards ahead, such as roundabouts, crossroads, dangerous bends or anything else that would call on you to drive more carefully. You should always take special care when you see a warning sign. If you fail to observe these signs you could create an emergency.
What they look like
All warning signs have the same format. They:
- are diamond or rectangular shaped,
- have a yellow background with a black border, and
- use a black symbol to show the hazard ahead.
They are also upright, meaning they are at the side of the road or mounted on a wall instead of painted onto the road surface.
This diagram shows some of the most common warning signs.
