What must a driver on the right-hand side of the road do to prepare for a left turn?

To prepare for a left turn while driving on the right-hand side of the road, it is crucial for the driver to follow a sequence of steps that enhances safety and proper execution of the maneuver. The selected approach involves first watching traffic from behind to ensure that no vehicle is approaching closely, which could pose a hazard during the turn. After assessing the surrounding conditions, signaling is necessary to communicate the driver's intention to turn left, allowing other road users to anticipate the movement. Finally, moving next to the center line provides a clear path for the turn and positions the vehicle correctly to make the left turn safely.

This method is essential as it takes into account various elements of road safety, such as awareness of traffic and adhering to signaling protocols. Driving practice emphasizes the importance of being vigilant and prepared, which is why this answer aligns with standard road user behavior and the principles taught in defensive driving courses.
