What does a "No U-turn" sign mean?

  1. You can make a U-turn at any time

  2. You may make a U-turn from a one-way street to another one-way street

  3. You may make a U-turn under certain conditions

  4. You may not make a U-turn

The correct answer is: You may not make a U-turn

A "No U-turn" sign means that you are not allowed to make a U-turn at that particular location. This is usually indicated on roads where it is dangerous to make a sudden turn, such as on a busy road or on a sharp bend. options A, B, and C are incorrect because they suggest that U-turns are allowed in certain situations, whereas the "No U-turn" sign specifically prohibits them. Option B is incorrect because it only specifies U-turns from one one-way street to another, but a "No U-turn" sign applies to all roads. It is important to follow signs and not make U-turns where they are prohibited for the safety of yourself and others on the road.
