When you see a DO NOT ENTER sign, what should you do?

• A. Proceed past the sign
• B. Don't proceed past the line
• C. Turn around and enter
• D. Ignore the sign

Answer: (B)

A Do Not Enter sign tells you not to go beyond that point. It marks a road where entering would put you going the wrong way or into a restricted area. The best action is to stop and not proceed past the line, then turn around at the next safe opportunity to take a different route. This keeps you out of traffic in the wrong direction and reduces collision risk. The other options would send you into a prohibited area, in the wrong direction, or ignore the sign, which are unsafe and illegal.
