When traffic lights are out or not working, no one automatically has priority ; drivers must generally treat the junction as an uncontrolled or all-way stop and use standard right-of-way rules, giving way to whoever clearly arrived first and then to the vehicle on the right if they arrive at the same time. Local laws can vary slightly by country or state, but the core idea is to slow down, be prepared to stop, and proceed cautiously while yielding rather than assuming priority.

Basic rule: nobody “owns” the junction

  • Many driving-theory resources state that when signals fail, nobody has automatic priority , and drivers must negotiate the junction using normal right-of-way rules.
  • This means you cannot rely on your usual green light; you must look, assess who is already at or in the junction, and yield where necessary.

How to act at a dead traffic light

  • Most guidance says to treat a completely dark signal like an all-way stop: come to a full stop, check all approaches, and only proceed when it is clearly safe.
  • Priority usually goes to:
    • The vehicle that arrived and stopped first.
* If vehicles arrive at the same time, the one on the right normally has right of way.

* Drivers turning left must still yield to oncoming traffic going straight, and everyone must yield to pedestrians.

Special signal situations

  • If the signal is flashing red in all directions, it should be treated like a four-way stop with the same “first come, then vehicle on the right” priority rules.
  • If one direction is flashing yellow and another has flashing red, the red side must stop and yield, while the yellow side proceeds with caution but does not automatically have full priority over everyone else.

Practical safety tips

  • Slow down early, scan for road users who are already in or clearly committed to the junction, and let them clear it first.
  • Make eye contact where possible, use clear signalling, and do not insist on your “rights” if another driver appears confused or aggressive; safety takes precedence over theoretical priority.

Mini scenario story

Imagine the power goes out at a busy crossroads during the evening rush.

  • One car from the north reaches the line and stops first; a moment later, two cars reach from east and west at the same time. The north car goes first, having clearly arrived and stopped before the others.
  • Next, the car to the right (say, from the east) goes, while the car on its left waits, following the “yield to the right” rule, and pedestrians cross only once each driver has visibly yielded.

Bottom line: in almost all places, when traffic lights are out, no one has built-in priority —treat it like an all-way stop, let the first arrival go, yield to the right if you arrive together, and always prioritise pedestrians and clear safety over “being in the right”.
