In the United States, when traffic lights are not working or are flashing, specific procedures known as "flashing signal rules" are followed to manage traffic flow safely. Here's a general guideline for how to proceed when traffic lights are not functioning properly:
Treat it as a Stop Sign: When the traffic lights are completely dark or not working at all, treat the intersection as if it has a stop sign in all directions. This means that all drivers approaching the intersection must come to a complete stop before proceeding further.
Right-of-Way: After coming to a complete stop, drivers should yield the right-of-way according to the normal rules at a stop sign-controlled intersection. The first vehicle to arrive and come to a complete stop should be the first to proceed, followed by the others in the order of arrival.
Caution and Safety: Exercise caution and be watchful for other drivers, pedestrians, and cyclists. Always be prepared to yield or stop if necessary, even if it is your turn to proceed. Use your turn signals to indicate your intentions, and follow the appropriate traffic rules and regulations.
Flashing Signals: If the traffic lights are flashing instead of being completely dark, they are typically operating in "flashing mode." In the U.S., flashing yellow lights indicate caution, and drivers should proceed through the intersection with care, yielding to any vehicles or pedestrians with the right-of-way. Flashing red lights, on the other hand, are treated as stop signs, and drivers must come to a complete stop before proceeding.
It's worth noting that specific traffic laws and guidelines may vary from state to state, so it's always a good idea to familiarize yourself with the local traffic laws and regulations in the area where you are driving. Additionally, if you encounter a malfunctioning or non-functioning traffic light, it's advisable to report it to the local traffic authorities or law enforcement to ensure prompt attention and repairs.
