Final answer:
You must wait until you can proceed completely through the intersection when the other side is backed up. This prevents traffic blockages, enhances pedestrian safety, and aligns with road safety practices to reduce accidents.
Step-by-step explanation:
If traffic on the other side of an intersection is backed up and you cannot get completely through, you must: c) Wait until you can proceed completely through. This rule helps prevent blockages at intersections, which can cause gridlock and additional traffic complications. Flashing your headlights, reversing out of the intersection, or staying in the intersection until traffic clears are not correct or safe practices in this situation.
Ensuring that you can clear the intersection entirely before entering prevents disruptions in the flow of traffic and also increases pedestrian safety. This is crucial in areas with heavy foot traffic, such as near a campus, where pedestrians need to be able to cross safely without having to dodge cars that are stuck in the intersection.
Moreover, maintaining an unobstructed intersection aligns with broader road safety practices aimed at reducing accidents. High traffic densities and impatient driving can lead to frequent accidents, some with severe consequences. Obeying traffic rules by only entering an intersection when it is clear to do so on the other side is part of being a responsible driver.
