Controlled Intersection
When you see flashing red lights at a 4-way stop Light instead of normal traffic signals you should approach the intersection as if it was a 4-way stop sign, alternating N/S and E/W lanes proceeding through the intersection, one car at a time. Typically this type of situation happens when the traffic signal system is malfunctioning.
you stop - look in all directions - and proceed if clear of opposing traffic.
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).
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.
You must stop
This differs depending on the intersection. Some intersections are forever flashing red. Some intersections only turn green when there is a trigger such as a pressure-pad or a crossing signal.
stop... A police officer assuming control of that intersection will have precedence over a traffic signal. If their signals are contrary to the traffic signal, you'll follow their signal.
The traffic signal is on a timer. It helps regulate traffic through an intersection.
about $150,000 for a 4-legged intersection about $250,000-$300,000 for a highway/cross-street intersection
In the U.S.A it means you have the right of way but proceed with caution.
