Regulatory, Lane & Parking SignsStandalone practice
You are about to turn onto a road. Facing you is a sign with a red circle and a white horizontal bar. What does it tell you?

Correct answer: You may not enter; the road is one-way against you or closed to vehicles
Why
You often see this sign at freeway exit ramps and one-way streets, where entering would put you head-on with traffic. Red on a sign means stop, yield, do not enter, or wrong way. If you pass this sign by mistake, a WRONG WAY sign may be the next warning.
