You missed your street and want to go back. At the next intersection, a white square sign shows a black U-shaped arrow under a red circle and slash. What should you do?

Correct answer: Drive on and turn around later, where it is legal and safe
Why
A red circle with a slash always shows a banned action, and the symbol inside tells you which one, such as a U-turn, a right or left turn, or trucks. Where no sign bans it, North Dakota still allows a turnaround only when it is safe and does not interfere with other traffic. You may not make a U-turn on a curve or near the top of a hill where other drivers cannot see you within 500 feet.
