Pennsylvania State Police and PennDOT are reminding drivers in Pennsylvania about the importance of using caution when driving through work zones. The two organizations held a press event yesterday to discuss Operation Yellow Jacket, a joint effort designed to maintain highway safety for all motorists and road crews. As part of the program, troopers monitor traffic inside PennDOT-designated work zones and if a violation is observed, they communicate to another trooper in a marked patrol unit to initiate a traffic stop. State law requires drivers to slow down, turn on their headlights, and obey all posted speed limits and traffic patterns when driving through work zones.
