Each year, the City receives many inquiries concerning the operation and installation of traffic signals within the City. The public's understanding of the function of traffic signals can improve driving habits by reducing speeding and associated traffic accidents. The more drivers know about the operation of traffic signals the less they will be frustrated when waiting for a signal to change.
Traffic signals are valuable devices for the control of vehicles and pedestrian traffic. As traffic volumes increase beyond the capability of lesser controls such as a four-way stop, it may be necessary to install a traffic signal. Before installing a traffic signal at an intersection, established minimum criteria must be satisfied.
Special Signal Functions
According to the California Vehicle Code, when a red lens is illuminated with rapid intermittent red flashes, a driver shall stop before entering the crosswalk on the near side of the intersection. The driver may proceed, subject to the rules applicable to making a stop at a four-way stop controlled intersection.
When a yellow lens is illuminated with rapid intermittent yellow flashes, a driver may proceed with caution through the intersection or past the signal.
When a traffic signal has gone dark, due to power failure, it is considered to function the same way as a four-way controlled intersection. A driver must stop before entering the intersection.
The City is committed to providing the safest, most efficient and advanced Traffic Signal System available. If you have any community traffic concerns, questions, or suggestions, please call the Irvine Traffic Research and Control Center (ITRAC)
