What if a traffic signal is blacked out (loss of power)?
According to the California Vehicle Code, when a signalized intersection is blacked out due to a loss of power, all motorists must treat the intersection as an all-way stop. If the signal is operating, but you notice a malfunction such as a light bulb burned out or some other problem, please call the Engineering Division at (916) 746-1300 during normal business hours.
