What is the main goal of performing a U-turn?

Performing a U-turn is primarily intended to allow a driver to change their direction of travel to face the opposite way. This maneuver is often used when a driver realizes they need to head in the reverse direction but are unable to do so through other means, such as turning at intersections or finding a larger area to turn around. A U-turn enables the vehicle to pivot in a relatively tight space, making it a practical solution for reversing one's direction on a roadway without needing to backtrack or find a longer route.

While other options mention actions like changing lanes, parking, or navigating around obstacles, these do not encapsulate the U-turn's specific purpose. The focus of a U-turn is solely on changing the vehicle’s course to head in the opposite direction, which is essential knowledge for drivers to maneuver safely and effectively in various driving situations.
