A U-turn is a driving maneuver that allows a vehicle to turn around and head in the opposite direction. This is typically done by making a 180-degree turn in the road, often at intersections or designated U-turn areas. U-turns can be useful for drivers who need to change their route quickly and efficiently. In many places, U-turns are regulated by traffic laws. Drivers must ensure that the maneuver is safe and legal, as some intersections may prohibit U-turns. Additionally, traffic signs may indicate whether U-turns are allowed, and drivers should always check for oncoming traffic and pedestrians before executing the turn.
