When making a left turn at an intersection, a motorist must yield to:

Answer: A — Cross traffic

A motorist must yield to cross traffic when making a left turn at an intersection because cross traffic has the right of way and is approaching from the opposite direction. Oncoming traffic is already stopped by a red light or stop sign and will not interfere with the left turn. Pedestrians may also have the right of way at the intersection, but they are not the priority when making a left turn. Vehicles behind do not have the right of way and must wait for the motorist to complete their left turn before proceeding. Therefore, cross traffic is the most important factor to yield to when making a left turn at an intersection.
