Traffic signs warn you of possible dangers and provide information. They tell you what the rules are and what the road conditions are like.
Regulatory signs tell you about laws that must be obeyed.
Except for STOP, GIVE WAY and ROUNDABOUT signs, most regulatory signs are rectangles. They are usually black on a white background. Sometimes they also have a colour such as red. Some parking signs are green on white.
Warning signs tell you that there may be dangers ahead. They are usually black on a yellow background and are mostly diamond shaped.
Pictures, diagrams and symbols are used to alert you to danger.
