PennDOT is implementing a new type of traffic signal to provide a safer, more efficient left turn for motorists. The flashing yellow arrow indication is a new type of display that will replace the circular green indication for left turns at signalized intersections.
The signal is more intuitive to motorists and, according to national data, can reduce left-turn crashes by as much as 20 percent!
