What to Do If a Traffic Signal Is Not in Operation

A power outage may affect traffic signals throughout Chester County. Instead of a green, yellow, or red signal, there may be an unlighted traffic control signal. According to the PA Vehicle Code, Chapter 31, if a traffic signal is out of operation or not functioning properly, vehicular traffic "shall stop in the same manner as at a stop sign, and the right to proceed shall be subject to the rules applicable after making a stop at a STOP sign." In other words, a non-functioning signalized intersection becomes a 4-way stop. So, the next time you come across a traffic signal that is not in operation... stop! It could save your life. If you have questions, please contact the West Whiteland Police Department at 610-363-0200.
