The eight-sided red STOP sign means that you must make a full stop before entering a crosswalk or at a white "limit line". A limit line is a wide white line painted on the street. When a crosswalk or limit line is not marked, stop at the corner.
Check for traffic before crossing. Wait until it is safe before going forward.
The three-sided red YIELD sign means slow down, be ready to stop, and let traffic (including people walking or riding bikes) pass before you go proceed.
DO NOT ENTER sign tells you vehicles will be coming toward you, usually on a freeway off ramp.
The WRONG WAY sign may be posted with the DO NOT ENTER sign. If you see one or both of these signs, drive to the side and stop. You are going against traffic. When safe, back out or turn around and go back to the road you were on.
Many road signs warn you to slow down or watch for hazards ahead.
Example: The signs shown below are placed where a cement separation strip or wall ends. These signs warn you that the center of the two-way road will only be marked by lines painted on the road.
Black and white signs like these tell you what to do. You must obey them.
Guide signs come in green, blue and brown. They help motorists to take their bearings and tell which services are available in the vicinity.
