Regulatory Signs: These signs are square, rectangular, or have a special shape and are usually white or red with black, red, white or green letters or symbols. They tell you the requirements for stopping, yielding, traffic direction, lane use, turning, speed limits, parking and other special situations.

Some regulatory signs have a red circle with a red slash over a symbol. These signs prohibit certain actions, i.e., no left turn, no right turn, no U-turn, etc.

Slower Traffic Keep Right. This sign is posted for those driving slower than the normal speed of traffic on some multilane highways. It reminds the slow driver to drive in the right lane.
