When do you use more than two Traffic Controllers?
Answer:
1. When two Traffic Controllers cannot see each other and two-way radios are not available
2. When controlling traffic at a T-junction or Roundabout (IN this situation it is critical to have two-way communication for all the Traffic Controllers)
3. When controlling traffic involves side streets between the Traffic Control position
4. When the traffic queues get too long that the 'end of queue' approaches a blind corner or crest or blind spot that the approaching traffic does not have enough reaction time to slow down and stop
