What should you do when a traffic light is not functioning at an intersection?

When a traffic light is not functioning at an intersection, the appropriate response is to come to a complete stop, then proceed when it is safe. This is essential because a non-functioning traffic light effectively acts as a four-way stop. All drivers approaching the intersection must stop and assess the situation, ensuring it is safe to proceed before continuing through the intersection.

This response prioritizes safety by allowing drivers to check for other vehicles and pedestrians, reducing the risk of collisions. By requiring a complete stop, it ensures that everyone is on the same page and maintains orderly traffic flow, even in the absence of signals. Adhering to this practice also helps instill a standardized method for handling such situations, which is vital for all road users.

In contrast, merely proceeding with caution without stopping does not provide the necessary safety checks that a full stop requires. Yielding only to oncoming traffic could create confusion among other drivers who may also have the right of way. Following the vehicle in front without stopping could lead to accidents if the driver in front misjudges the intersection's safety.
