Temporary traffic control and flaggers in and around Work zones are used to move traffic in an approved direction and are typically identified by signs, cones, barrels, and barriers. 

Unfortunately, transportation incidents and workers struck by vehicles or mobile equipment account for the highest number of fatal work injuries, according to the Bureau of Labor Statistics.

The control of all road users through an effective temporary traffic control (TTC) zone is an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents.

Everyone involved in construction work zones should have a basic knowledge of temporary traffic control and flagging.
