To determine when and if traffic signals may be needed (warranted), traffic engineers compare existing conditions against nationally accepted minimum guidelines - often called "warrants". When these warrants are met, a traffic signal may be considered for installation.
One of the most common maintenance items is the changing of bulbs. If you observe a bulb out or what you believe is a traffic signal malfunction, please contact the city at 651-450-2500.
