During certain conditions, signals may revert to flashing operation. This may occur during non-peak hours, late at night, or signal malfunction. When a signal is in flashing mode, it will usually flash yellow for the major street and red for the minor street. Pedestrian signal heads are dark and APS is silent during flashing operation.
