Every sign type has its own color and shape so you can recognize it at a glance, and many use symbols instead of words. Red regulatory signs prohibit actions and control traffic through intersections. Rectangular black-on-white signs tell you what you must do.

Know the rule

Obey all official signs, signals and markings unless a police officer or road worker is redirecting traffic.

Handbook p. 15 ↗
Stop
Stop — octagon

Know the rule

Stop sign (octagon): come to a complete stop. Yield to other vehicles, and stop and stay stopped for pedestrians crossing in marked or unmarked crosswalks. Enter the intersection when it is safe.

Handbook p. 15 ↗
Yield
Yield — triangle

Know the rule

Yield sign (triangle): reduce speed and yield the right of way. If needed, stop the same as you would for a stop sign.

Handbook p. 15 ↗
Do not enter
Do Not Enter — square

Know the rule

Do Not Enter (square): don't enter the road or freeway. You'll see this sign if you are going the wrong way.

Handbook p. 15 ↗
No bicycles
No Left Turn

Know the rule

A red circle with a slash means do not make the movement shown — for example No Left Turn, No Right Turn or No U Turn.

Handbook p. 15 ↗

Regulatory sign

A rectangular sign with black words or symbols on a white background that tells you what to do. It is posted at or near where the requirement applies.

Handbook p. 16 ↗
Speed limit
Speed Limit

Know the rule

Speed Limit: the maximum speed in miles per hour. Speed limit signs may be electronic and may change based on current conditions.

Handbook p. 16 ↗

Know the rule

One Way: traffic flows only in the direction of the arrow.

Handbook p. 16 ↗
Right turn permitted without stopping
Right Turn Permitted Without Stopping

Know the rule

Right Turn Permitted Without Stopping may appear below a stop sign. Traffic turning right may turn without stopping; all other traffic must stop and yield the right of way.

Handbook p. 16 ↗

Put it into practice

You reach a stop sign with a RIGHT TURN PERMITTED WITHOUT STOPPING plate below it. Turning right, you may continue without stopping. If you were going straight or turning left, you'd make a full stop and yield first.
