What should a driver do if they encounter a slow-moving vehicle on a highway?

Answer: B — Be patient and pass only when safe and legal

When a driver encounters a slow-moving vehicle on a highway, the most appropriate action is to be patient and pass only when it is safe and legal to do so. This approach helps maintain safety on the road by ensuring that maneuvers are executed thoughtfully and in accordance with traffic laws. Attempting to speed up to pass quickly can create dangerous situations, especially if it involves aggressive driving behavior or risking a collision. Honking as a way to notify other drivers is also not a constructive action; it can lead to confusion or provoke unnecessary reactions. Changing lanes frequently can cause disruption to the flow of traffic and increase the likelihood of an accident. Therefore, exercising patience and waiting for a clear and safe opportunity to pass is the most responsible choice, as it prioritizes safety for all road users.
