What is the meaning of a "No U-Turn" sign?

U-Turns are permitted
U-Turns are prohibited
You may only turn right
You may only turn left

The correct answer is: U-Turns are prohibited

A "No U-Turn" sign means that making a U-turn is prohibited and not allowed at that particular location. This sign is placed to alert drivers that they cannot make a complete turn in the opposite direction and must find an alternate route. U-turns can be dangerous and disruptive to traffic flow, hence the reason for this restriction. Option A is incorrect because it implies that U-turns are allowed, which is contradictory to the sign's meaning. Option C is incorrect because it limits the turn to only one direction, while both right and left turns would be prohibited. Option D is also incorrect for the same reason, only it limits the turn to the opposite direction. It is important to follow these road signs to ensure the safety of yourself and other drivers on the road.
