California Driver Handbook - Traffic Controls
Pedestrian signals show words or pictures similar to the following examples:
"Walk" or "Walking Person" signal light means it is legal to cross the street.
"Don’t Walk" or "Raised Hand" signal light means you may not start crossing the street.
Flashing "Don’t Walk" or Flashing "Raised Hand" signal light means do not start crossing the street because the traffic signal is about to change. If the signal light starts flashing after you have already started to cross, finish crossing the street as quickly as possible.
Countdown signals indicate how many seconds remain for crossing. These signals allow pedestrians the flexibility to speed up if the crossing phase is about to expire.
Some signals may provide a beeping or chirping sound or a verbal message. These signals are designed to help blind or visually impaired pedestrians cross the street.
At many traffic signals, you need to push the pedestrian push button to activate the "Walk" or "Walking Person" signal light. If there are no pedestrian signals, obey the traffic signal lights
The shape and color of a sign gives you a clue about the information contained on the sign. Here are the common shapes used:
An eight-sided red STOP sign indicates that you must make a full “STOP” whenever you see this sign. Stop at the white limit line (a wide white line painted on the street) or before entering the crosswalk. If a limit line or crosswalk is not painted on the street, stop before entering the intersection. Check traffic in all directions before proceeding.
A three-sided red YIELD sign indicates that you must slow down and be ready to stop, if necessary, to let any vehicle, bicyclist, or pedestrian pass before you proceed.
A square red and white regulatory sign indicates that you must follow the sign’s instruction. For example, the DO NOT ENTER sign means: do not enter a road or off ramp where the sign is posted (usually on a freeway off ramp). The WRONG WAY sign may or may not be posted with the DO NOT ENTER sign. If you see one or both of these signs, drive to the side of the road and stop. You are going against traffic. When safe, back out or turn around and return to the road you were on. At night if you are going the wrong way, the road reflectors will shine red in your headlights.
If a sign has a red circle with a red line through it, it always indicates “NO.” The picture inside the circle shows what you cannot do. The sign may be shown with or without words.
A yellow and black circular sign means you are approaching a railroad crossing.
X-shaped signs with a white background that state RAILROAD CROSSING indicate that you must look, listen, slow down, and prepare to stop, if necessary. Let any trains pass before you proceed.
Five-sided signs mean you are near a school. Stop if children are in the crosswalk.
A four-sided diamond-shaped sign warns you of specific road conditions and dangers ahead. Many warning signs are diamond-shaped.
A white rectangular sign means you must obey important rules.
Some warning signs have a fluorescent yellow-green background. These signs warn of conditions related to pedestrians, bicyclists, schools, playgrounds, school buses, and school passenger loading zones. Obey all warning signs regardless of their shape (See above for examples of traffic signs).
