Question 2

Which of the following best describes the 'Termination Area' of a temporary traffic control zone?

The termination area is the downstream end of the work zone where the traffic lanes return to normal configuration.

Question 3

What action should a flagger take if a signal from a two-way radio is lost mid-operation?
