Road departments use traffic signs and signals for communicating with drivers, and in order to drive safely, every driver needs to know instantly what each sign means.

The overall shape of road signs also contains information for drivers. 

Rectangular signs are used for conveying information about driving regulations, such as speed limits. Octagonal signs are used for stop signs, and diamond-shaped signs signal a warning of a road hazard. Triangular signs are used for indicating a need to yield to traffic in another roadway.

Roadway Light Signals

Road signs and signals also include flashing and steady lights. Steady red lights signify that drivers must come to a complete stop before proceeding if proceeding on a red light is permissible at that location. Flashing red lights signal drivers to come to a complete stop and then proceed when safe to do so.

Some states, such as California, allow drivers to turn right after coming to a complete stop at a red light, but in other states, you can receive a traffic ticket for doing this. 

Steady yellow lights mean a red light is about to appear. If you are close to the intersection and you can pass through it safely before the light turns red, you can drive through a yellow light. However, if you can safely stop, you should do so. 

Green lights mean go ahead, but only if it is safe to do so. A steady green arrow means you can drive in the direction of the arrow, as long as it is clear of other vehicles and pedestrians.
