You must stop
A red light - steady or flashing - means STOP. A steady amber light means Caution - signal about to change. A flashing amber light means SLOW DOWN.
Amber in the traffic signal means caution. Generally, it is best to stop on an amber light.
Amber flashing light.
No, Flashing your headlight's will have no effect on a traffic signal. The reason a traffic signal changes for emergency vehicles that have the lights flashing, is, they have a special transmitter that tells the light to change. This transmitter is connected to the emergency lights so it comes on when the lights are used.
Flashing amber light means slow down, watch for potential dangers. Flashing red means stop; proceed if and when it is safe.
In the U.S.A it means you have the right of way but proceed with caution.
If there are pedestrians still crossing when the amber light is flashing, the motorist must remain stationary. If there are no pedestrians crossing, the motorist can proceed. (But, be careful of pedestrians taking a chance and attempting to cross when the amber light is flashing - it is best to use caution until the light turns green.)
It means you should slow down and be prepared to stop if necessary. "Slow down and cross the intersection carefully."
Red=stop red flashing= light is broken, use your judgement in crossing.
You must proceed with caution and be prepared to stop if necessary. If it is in a school zone, slow to 20 miles per hour.
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.
It means you should slow down and be prepared to stop if necessary. "Slow down and cross the intersection carefully."
