MOT Flagging Operations & Procedures 4 — Questions and Answers
Question 1: A flagger's shadow station should ideally be positioned so the flagger can see at least how far in each direction?
- 100 feet
- 250 feet
- 500 feet (Correct answer)
- 1,500 feet
Correct answer: 500 feet
Flaggers should have a minimum sight distance of 500 feet in both directions to allow adequate response time for approaching vehicles.
Question 2: Which of the following is the correct sequence for transitioning from STOP to SLOW when releasing a queue?
- Rotate paddle to SLOW before stepping aside, then gesture to proceed
- Step into the lane first, then rotate to SLOW
- Display SLOW, make eye contact, and wave traffic through with the free hand (Correct answer)
- Call the opposite flagger, rotate to SLOW, then stand aside
Correct answer: Display SLOW, make eye contact, and wave traffic through with the free hand
The proper release sequence is: display SLOW, establish eye contact, and use the free hand to wave traffic through at a safe pace.
Question 3: What should a flagger do if they experience fatigue or become unable to perform duties safely during a shift?
- Continue working until the next scheduled break
- Notify the supervisor so a relief flagger can be assigned (Correct answer)
- Hand the paddle to a nearby construction worker temporarily
- Sit down briefly in the shoulder and resume when rested
Correct answer: Notify the supervisor so a relief flagger can be assigned
A fatigued flagger must immediately notify the supervisor so a qualified relief can be assigned — unfit flagging is a serious safety hazard.
Question 4: Which sign is typically used to inform drivers that the flagger-controlled section has ended?
- END ROAD WORK (G20-2) (Correct answer)
- FLAGGER AHEAD (W20-7a)
- ROAD WORK NEXT X MILES (G20-1)
- ONE LANE ROAD AHEAD (W20-4)
Correct answer: END ROAD WORK (G20-2)
The END ROAD WORK sign (G20-2) is placed at the downstream termination area to signal the end of the temporary traffic control zone.
Question 5: When a pilot car is used, what information must the pilot car operator communicate to the waiting flagger before releasing the next queue?
- The number of vehicles that passed through
- Confirmation that the one-lane section is clear of oncoming traffic (Correct answer)
- The exact speed vehicles traveled through the zone
- The weather conditions observed in the work zone
Correct answer: Confirmation that the one-lane section is clear of oncoming traffic
The pilot car operator must confirm the one-lane section is clear before the opposite flagger releases the next queue of vehicles.
Question 6: How should a flagger handle an emergency vehicle (police, fire, ambulance) approaching the STOP station?
- Hold STOP and wait for the emergency vehicle to turn around
- Immediately release all held traffic to clear the road
- Allow the emergency vehicle to pass through while keeping other traffic stopped (Correct answer)
- Direct the emergency vehicle to use an alternate route
Correct answer: Allow the emergency vehicle to pass through while keeping other traffic stopped
Emergency vehicles must be allowed to pass through the flagging station while all other traffic remains stopped until the emergency vehicle clears the zone.
Question 7: What is the purpose of the buffer space in a temporary traffic control zone?
- To store construction materials safely
- To provide a safety margin between traffic and the work activity area (Correct answer)
- To serve as a staging area for flaggers
- To separate advance warning signs from each other
Correct answer: To provide a safety margin between traffic and the work activity area
The buffer space is an empty area that separates live traffic from the active work area, reducing the risk of vehicle intrusion into the work space.
