Severe weather can interrupt local electric service and cause roadway traffic signals to go out.
Always remember to stop at intersections where the traffic signals are out. Look in all directions for other approaching vehicles, then cross through the intersection when it is safe to proceed. Treat a blacked-out traffic signal like a four-way intersection.
Come to a complete stop at a flashing red signal. Then proceed when it is safe. Slow down and be extra alert through an intersection with a flashing yellow signal.
