You must obey all official signs, signals, and markings unless you see a police officer or road worker redirecting traffic.
Signs often use symbols or pictures rather than words. Each type of sign has a special color and shape to help you easily recognize the sign at a glance.
Traffic signs that prohibit certain actions or movements are red in color and increase safety by controlling the flow of traffic through intersections.
This sign means you must come to a complete stop. Yield to other vehicles and stop and stay stopped for pedestrians crossing in marked or unmarked crosswalks. When it is safe, you may enter the intersection.
This sign means you should reduce speed and yield right of way. If needed, stop the same as you would for a stop sign.
Do Not Enter—Square
This sign warns you not to enter a road or freeway. You will see this sign if you are going the wrong way. Study For Your Tests

Traffic signals control the right of way and provide for a smooth, orderly flow of traffic. If a signal appears dark, such as during a power failure, you should stop as if there are stop signs in all directions. When a traffic signal is out of order and flashes yellow or red, you must obey that signal.
steady red signal means stop and remain stopped until the signal changes.
You are allowed to make the following turns on red after coming to a complete stop unless a sign or police officer states otherwise:
- When entering a two-way road, you may turn right.
- When entering a one-way road, you may turn right or left in the direction of the one-way road.
flashing red signal is treated the same as a stop sign.
steady red arrow means stop and remain stopped until the signal changes, except for allowed turns on red. The same turns allowed for a steady red signal are allowed for a red arrow.

steady yellow arrow warns you that the signal is about to turn red. Stop before entering the intersection, or if you cannot stop safely, drive carefully through it.
