Traffic Control Drivers operate vehicles to set up and maintain traffic control devices, requiring a valid driver’s license and often a CDL. Flagger personnel manually direct traffic using flags or signs, focusing on safety and manual signaling. Both roles are essential in work zones but differ mainly in vehicle operation versus manual traffic directing.
