Work-Zone Safety, Temporary Traffic Control, and Flagging (CTAP)


In this four-hour comprehensive workshop, attendees will learn key elements required for temporary traffic control, safety, and flagging. Working next to traffic can be dangerous and errors can cause accidents, so it is important for personnel to have a solid understanding of roles, responsibilities, and liability. Safety is incorporated into every aspect of this training. Group exercises and open discussion will keep attendees engaged and enhance learning. In recognition of the high percentage of injuries that happen to employees, refresher courses and continual education is highly recommended.
