When making a left turn, what must the driver of vehicle 1 do first?

When making a left turn, the driver of vehicle 1 must first pull up to the intersection. This action positions the vehicle correctly in the turning lane, ensuring that the driver has a clear view of oncoming traffic and any pedestrians present in the crosswalk. It is essential for safety and proper execution of the turn.

Once at the intersection, the driver can appropriately assess traffic conditions, including the direction and distance of oncoming vehicles, which helps in deciding the best moment to turn. Consequently, the practice of pulling up to the intersection aids in minimizing confusion and ensures that the driver is making informed decisions while preparing to execute the turn.

Other factors, such as signaling and merging into traffic, come into play but only after the vehicle is properly positioned at the intersection. Waiting for other vehicles to pass may be necessary depending on the situation, but the initial requirement before any of those actions is to pull up to the intersection.
