What should drivers do if the traffic lights at an intersection are not functioning?

When traffic lights at an intersection are not functioning, the appropriate action for drivers is to treat the intersection as an all-way stop. This means that all vehicles must stop before proceeding. This is essential for maintaining safety and order at an intersection where traffic signals are not operational.

Traffic lights are designed to facilitate the flow of traffic and provide clear instructions on when to stop and go. When they stop working, it removes that guidance, leading to potential confusion about the right of way. By having all vehicles come to a complete stop, drivers can observe the traffic in all directions and safely proceed according to the standard rules that govern stop signs—yielding to other vehicles and pedestrians who may have the right of way.

Additionally, options that advocate for speeding up, yielding without stopping, or proceeding without stopping if it's clear do not prioritize safety. These alternatives could lead to accidents, as drivers may misjudge the actions of other vehicles, thereby increasing the risk of collision. Therefore, stopping at an intersection where traffic lights are out is the best approach to ensure safety for all road users.
