The phrase "does a u-turn" is a common expression used to describe turning around and heading in the opposite direction. However, there are several other synonym phrases that can be used to convey the same meaning. These include "makes a 180," "turns around," "backtracks," "reverses course," and "flips a U-ie." All of these phrases communicate the idea of turning a vehicle or one's direction entirely around to head in the opposite way. Although each phrase may have its own distinct connotation, they all share the central notion of changing the direction of one's movement.
