When is a three-point turn necessary?

A three-point turn is primarily necessary when the road is too narrow to perform a U-turn. This maneuver allows a driver to turn their vehicle around in a confined space where a traditional U-turn would not be feasible. By making a three-point turn, the driver can successfully navigate their vehicle to face the opposite direction without needing a broader area.

In scenarios such as a traffic jam, the vehicle may be unable to maneuver safely, making a three-point turn impractical. Similarly, while the presence of no traffic on both sides of the road might suggest a safe scenario, it does not specifically warrant a three-point turn as the best choice. Vehicles blocking the lane may also impede the ability to execute a successful three-point turn, reinforcing the need for the road to be adequately clear and wide enough for effective maneuvering.
