Green Light
This signal means GO. You may go through an intersection in the direction indicated by the signal if the roadway is clear. Check left and right for cross traffic before entering the intersection to avoid a collision with a red light runner. Yield to any vehicle that is already in the intersection when the light changed.
Manual page 34
Yellow Light
This signal means CAUTION. A steady yellow light is a warning that the light is about to turn red. If you have not entered the intersection, you should come to a safe stop. If you are already in the intersection, you should continue moving and clear it safely. Speeding up to “beat the light” is illegal and could cause a crash.

Red Light
This signal means STOP. You must come to a complete stop before you reach the intersection, stop line or crosswalk. Remain stopped for as long as the light stays red. Where not prohibited by signs, a right turn may be made after coming to a complete stop, when motor traffic and pedestrian traffic are clear.

Flashing Red Light
A flashing red light has the same meaning as a stop sign. You must come to a full stop, then proceed with caution when the roadway is clear.
