Final answer:
Treat a broken traffic light as if it were flashing red; stop completely before proceeding and follow right-of-way rules for safety.
Step-by-step explanation:
If you approach an intersection with traffic lights which are broken, you should treat it as if all lights are flashing red. This means you must come to a complete stop before entering the intersection, and proceed when it is safe to do so, treating it like a stop sign. The priority can be established by the order in which vehicles arrived at the intersection, or by yielding to the vehicle on your right if you both arrive at the same time.
It is important to note that treating a broken traffic signal as if it were flashing red ensures maximum safety for all road users. This approach slows down vehicles and allows for a controlled flow of traffic, thereby reducing the risks of accidents. Pedestrian safety is also enhanced, as vehicles are required to stop, providing pedestrians with the opportunity to cross safely.
