Regulatory signs tell you the law: stop, yield, speed, lane use, parking and prohibited moves. Most are red or black on white.

Know the rule

Stop sign: make a complete stop at the stop line; if none, before the crosswalk; if no crosswalk, before the sign. Yield to pedestrians or bicyclists in the crosswalk, then proceed cautiously when the roadway is clear.

Put it into practice

You're about to turn onto a street and see a red-and-white DO NOT ENTER sign facing you. It's one-way the other direction. Don't turn in; find another route.
