What must a driver do at an intersection when traffic lights are not functional?

When traffic lights are not functioning, a driver must follow normal traffic rules as if it were a stop sign. This means that the driver should come to a complete stop and yield the right of way to any vehicles or pedestrians that may have the right of way at that intersection. Traffic rules dictate that at intersections without functioning lights, it is essential for drivers to treat the situation with caution to prevent accidents.

This rule is important because it maintains order and safety on the roads, especially when traffic signals fail, which can create confusion and potential traffic hazards. By treating the intersection like a stop sign, drivers help ensure that everyone approaches the intersection with a clear expectation of stopping and yielding, thereby reducing the risk of collisions.

In contrast, proceeding without stopping could lead to accidents, as other drivers may also be approaching the intersection without understanding who has the right of way. Yielding only to vehicles on the right could create misunderstandings, especially if multiple vehicles arrive at the same time from different directions. Following the direction of a traffic officer is crucial when present, but this option only applies if an officer is directing traffic. Thus, the most appropriate and universally applicable action in the absence of functional traffic lights is to treat the intersection like a stop sign.
