How should you approach traffic signals that are not working?

When approaching traffic signals that are not working, treating the intersection as a four-way stop is the appropriate response. This means that all vehicles must come to a complete stop before proceeding through the intersection, just as they would at a stop sign. This practice promotes safety by ensuring that all drivers understand they must yield to any vehicles already in the intersection or those that arrive first.

This response is essential, as it helps to regulate traffic flow in instances where signals are non-functional and reduces the risk of accidents. By stopping and then proceeding with caution, drivers are able to make corrections based on the actions of other road users, thereby maintaining a predictable flow of movement that aids in overall traffic safety. It's important to remember that failing to treat a non-working traffic signal appropriately can lead to confusion and hazardous situations for drivers and pedestrians alike.
