Final answer:
A three-point turn is used to turn around on a narrow street. It involves multiple steps of maneuvering the vehicle in forward and reverse gears to change its direction when larger turns are not feasible.
Step-by-step explanation:
Drivers must use the three-point turn to turn around on a narrow street when it is not prohibited. The three-point turn is a method of turning a vehicle around in a limited space using forward and reverse gears. This maneuver is typically used in situations where the road is too narrow to perform a U-turn and there isn't enough space for a simpler turn.
When to Use a Three-Point Turn
The most common scenario for using a three-point turn would be on a narrow residential street where larger turns are not possible. It involves pulling over to one side of the roadway, reversing direction while turning into the opposing lane, and then moving forward to complete the change in direction. This maneuver should not be used on busy roads due to the risk of collisions with fast-moving traffic.
