What must you do if a traffic signal is out?

When a traffic signal is out, it is important to ensure the safety of all road users. Treating the intersection as a four-way stop is the correct approach because it establishes a clear set of rules for how drivers should interact when there's no signal directing traffic. At a four-way stop, each vehicle must come to a complete stop and yield to any vehicles or pedestrians that arrived before them. If two vehicles arrive simultaneously, the driver on the right has the right of way. This procedure helps to prevent confusion and potential accidents at an intersection where the usual rules of the traffic signal no longer apply.

Understanding this is crucial for maintaining safety on the roads; ignoring the signal or proceeding without stopping can lead to collisions, while waiting for a police officer may not always be practical or necessary, depending on the situation.
