Traffic Control Signals
Section 3112 a(3iii)c of the Pennsylvania Vehicle Code states if the traffic lights at an intersection are not functioning properly for some reason, all traffic on all roadways must treat it as an all-way stop intersection. An example of this would be when there is a power loss in an area where traffic control signals are present. All traffic must treat the intersection to be an all-way stop until the traffic control signals are functional again or a law enforcement officer is present to direct you through the intersection.
