A 3-minute lesson from the Kansas course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Warning signs tell you about possible danger ahead so you can slow down or prepare to stop. You'll recognize most of them by their shape and color before you can read them, which is exactly what the knowledge test checks.
Know the rule
Warning signs are usually yellow with black lettering or symbols and diamond shaped. Some, such as school zone, school crossing and pedestrian crossing signs, may be fluorescent yellow.

The No Passing Zone sign is the only pennant-shaped warning sign. It marks the beginning of a no-passing zone and sits on the left side of the road facing you.
You see a yellow diamond showing a car with wavy skid marks: Slippery When Wet. It's warning you of a possible hazard, so slow down, especially when rain is just starting and the road is slickest.
