A 2-minute lesson from the Wisconsin course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Warning signs tell you a hazard or special situation is ahead, so you can slow down before you reach it. You can spot them by color and shape: yellow, usually a diamond.
Know the rule
Warning signs are yellow with black lettering or symbols. Most are diamond shaped.
Police, school crossing guards and other workers sometimes direct traffic with signs. Follow their directions even if they differ from the traffic light or sign.

Put it into practice
You see a yellow diamond with a traffic light symbol on a 55 mph road. The signal itself is still out of sight. Ease off the gas now so you can stop smoothly if the light is red.
