No u turn sign: what does it mean?

Discover the No u turn sign.

Meaning, definition, shape, location, color, and more.

The no U-turn sign is a regulatory sign. No U-turn signs are posted at intersections to indicate the driver is not legally allowed to make a U-turn (a turn in the road to go the opposite direction). If a driver needs to make a 180 degree turn in a place marked no U-turn, they must wait for an intersection that allows this type of turn or find an alternate way such as going around a block.

Shape: Square

They are square with a black arrow that’s crossed out in red.

Location: Posted at intersections

No U-turn signs are posted at intersections or along roads where the driver can’t legally make a 180 degree turn.
