If a vehicle is going to turn, what must it do regarding vehicles going straight ahead?

Vehicles making a turn are required to yield the right of way to those proceeding straight. This rule is in place to ensure safety and minimize collisions at intersections. When a vehicle is turning, it can potentially obstruct the path of straight-moving traffic. By yielding to vehicles going straight, the turning vehicle helps maintain a smooth flow of traffic and reduces the risk of accidents.

The rationale here is based on the understanding that vehicles traveling straight have a clearer right of way, particularly at intersections where turns occur. This principle is a fundamental aspect of road manners and rules, fostering predictability and respect among drivers, which are essential components for safe driving environments.

In contrast, the other options do not correctly represent the right of way principles associated with turning vehicles. For example, yielding to vehicles in the right lane or to those behind does not prioritize the safety of the traffic patterns at intersections. Proper adherence to yielding rules is crucial for safe driving and effective traffic management.
