Traffic signals provide clear indication to drivers when it is safe to stop, go or slow down. In rare cases, a traffic signal may become inoperable, or the device may flash certain colors. If you approach an intersection and see the traffic signal is not functioning normally, follow these rules:
Flashing Red: If the traffic signal is flashing red, treat it as a stop sign and come to a complete stop at the intersection. Look carefully in all directions before proceeding. Other directions may have a different type of signal indication.
Flashing Yellow: If the traffic signal is flashing yellow, proceed cautiously through the intersection. You should also slow down and observe cross streets to determine if it is safe to proceed.
Inoperable (No Lights): If the traffic signal is completely inoperable, treat it as a 4-Way STOP. Remember that other drivers may not know how to react when a traffic signal is inoperable. Always stay alert and proceed cautiously through an intersection. No matter the condition of a traffic signal, you should always observe cross streets and other drivers to make sure you can proceed safely.
If the signal is on the state highway, you can call ODOT at1 (888) 275-6368. Otherwise call the Police Non-Emergency Line at (503) 325-4411.
