What defines a U-turn?

Answer: B — turn made in one smooth, U-shaped motion to go in the opposite direction

A U-turn is defined as a maneuver that allows a driver to change direction and proceed in the opposite direction using one smooth, U-shaped motion. This maneuver typically takes place on a roadway and does not require multiple steps or positions to execute. The emphasis is on the fluidity and simplicity of the movement, making it distinct from other types of turns that might involve complicated maneuvers or multiple lane changes. Other options describe turns that do not accurately capture the essence of a U-turn. For instance, a turn at an intersection might only involve a 90-degree angle or be a different type of turn altogether, while a wide turn could suggest an expansive arc or change that doesn’t fit the definition of a U-turn. Additionally, a turn with multiple maneuvers to reposition implies a far more complex action that is not characteristic of a U-turn, which is meant to be straightforward and efficient. Thus, the correct answer highlights the defining feature of a U-turn as a singular, smooth motion.
