The standard reply from law enforcement is to treat the intersection as a four way stop.
Usually there is a blinking red light, so it becomes the same as a stop sign. All rules apply .
If the traffic lights are not working, the intersection is treated like a 4-way stop. That is, as if everyone has a stop sign.
If the traffic light is not powered, you are to treat it as a all-way stop sign. I'm assuming that's what you mean by that. If the traffic light is broken, likely there will be utility workers out there working to fix it and you follow their instructions if any.
Stop light sensors are a loop of wire that is buried in the pavement and controls the traffic light. The sensors are able to detect the traffic that is waiting at the light.
the red light. it means STOP.
A signal light that is not working.
Traffic approaching the light is to stop. If the way is clear, traffic can then proceed through the intersection.
You need a traffic light because they let people need to know to stop or go.
An intersection that does not have a stop light or stop signs to control the flow of traffic
Stop signs
Stop light is another name for a traffic signal.
A flashing red traffic light is used the same way as a stop sign. You treat a flashing red traffic light the same way you do as a stop sign. If the traffic light is "blacked-out", it's to be treated as an all-way stop. What I do when I come up to a flashing red traffic light, I look at the cross-traffic signals to see if they're also flashing red, or if they're flashing yellow to see if they stop or if they don't stop.
Red - Stop Yellow - Prepare to Stop Green - Go
