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.
You should not be driving if unable to distinguish yellow from red. If uncertain- treat as red.
means nothing Wrong! It means caution. Something requires extra attention. At an intersection, a flashing circular yellow means to take extra caution, and watch for traffic on the cross road (which has a flashing red light). A flashing red light is the same as a stop sign. A flashing yellow arrow means you ma turn in the direction of the arrow, but you must yield to conflicting traffic. If the flashing yellow light is not at an intersection, it either calls attention to a road hazard on an accompanying sign, or indicates that a special regulation indicated on the sign is in effect (School speed limit 20 when flashing).
In the U.S.A it means you have the right of way but proceed with caution.
A flashing yellow light in aviation terms is a runway guard light.
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.
A flashing yellow light means you should drive with caution when approaching and moving through the intersection.
The red flashing traffic light means that you are to come to a stop, yield to other traffic and then you can procede when the way is clear.
It depends on the situation, the type of light and where it is situated.
It means you should slow down and be prepared to stop if necessary. "Slow down and cross the intersection carefully."
