Regulatory, Lane & Parking SignsStandalone practice
You are about to turn onto a ramp. A red circular sign with a white horizontal bar and the words DO NOT ENTER faces you at the start of the ramp. What does the sign mean for you?

Correct answer: You may not drive onto that ramp from your direction
Why
DO NOT ENTER signs are often at freeway exit ramps and at the ends of one-way streets, where traffic comes toward you. If you pass one by mistake and then see a red WRONG WAY sign, you are going against traffic on that street, freeway or ramp. Watch for these red signs each time you turn onto a ramp or an unfamiliar street.
