Which turnabout requires that you stop your car across traffic lanes?

The three-point turnabout is a maneuver typically used on narrow streets where you need to turn your vehicle around to head in the opposite direction. This method involves stopping your car across traffic lanes as part of the process.

During a three-point turnabout, you start by moving to the right side of the road and then steering left to create an initial turn into oncoming traffic. You then shift into reverse, backing across the street, before steering again to complete the turn in the desired direction. This maneuver can temporarily block lanes of traffic, requiring you to stop across the lanes during the execution of the turn, which can create a potential hazard if not done carefully.

The U-turn is typically performed in a single motion and does not usually require stopping in traffic lanes. The two-point turnabout is more of a simple maneuver involving backing into a driveway or a location, also without the need to stop in the lanes. A roundabout is a circular intersection designed to keep traffic flowing smoothly and does not involve stopping to perform a turnabout. Understanding the mechanics and legalities of these maneuvers is crucial for safe driving and complying with traffic laws.
