Traffic Control

Almost every job at one time or another needs traffic control. This often involves the use of a flagman and signs. In short duration situations flagmen are preferable to signs since they can react to any changes in site situations. Signs are however, a suitable solution to an extended traffic control problem.

It should be remembered that the intent of traffic control procedures is to prevent a tie-up in the operation of the construction project and to allow the general public to move as efficiently as possible around the construction site. It is important that all flagmen remember that they represent the company and will come into contact with many people while flagging. Therefore be courteous at all times.

Is the flagman trained and certified?


  • Pre-plan the entire traffic control operation.
  • Have the flagman knowledgeable of all construction – operations to occur.
  • Clearly mark all changes or detours.
  • Enforce all changes and detours.

Flagging Operations

  • Be sure the traffic can see you.
  • Wear an Orange safety vest.
  • Use a flag.
  • Wear suitable shoes.
  • Be dressed neatly (to reflect a good public image).
  • Wear a hard hat.
  • Never turn your back on the traffic.
  • Always be courteous but firm.


Remember: The flagman has a responsibility to protect the general public as well as those at work on the construction site. Pay attention to what is going on around you.
