What is the primary reason for using a three-point turn?

The primary reason for using a three-point turn is to make a U-turn in a narrow space. This maneuver allows a driver to turn their vehicle around to face the opposite direction when there isn’t enough room to execute a standard U-turn. The three-point turn is particularly useful in residential areas, smaller streets, or other restricted spaces where a full turn isn't feasible due to obstacles like parked cars or narrow roadways.

During a three-point turn, the driver typically moves to the right side of the road, turns the steering wheel sharply to one side to angle the vehicle, then shifts into reverse while the front of the vehicle swings out, and finally maneuvers into the opposite direction. This technique helps maintain control of the vehicle in tight spaces and is a valuable skill for bus drivers who may encounter similar situations while on the route.

Changing lanes without turning, reversing into a parking space, or temporarily parking do not specifically require this maneuver and can often be accomplished without the unique approach of a three-point turn, thus making those options less relevant to the primary use of the three-point turn.
