What this covers

Sample questions

What sign is displayed on a pilot car used to lead traffic through a one-lane section?

  1. ROAD WORK AHEAD
  2. PILOT CAR FOLLOW ME
  3. ONE LANE ROAD AHEAD
  4. DO NOT PASS
Show the answer

B. PILOT CAR FOLLOW ME

The pilot vehicle carries a PILOT CAR FOLLOW ME sign on its rear so the queue knows to follow it. The other signs are roadside signs, not the sign mounted on the pilot car.

A pilot car is used on a one-lane section. What does the flagger at each end do?

  1. Releases traffic every few minutes to catch up with the pilot car
  2. Holds traffic until the pilot car arrives and turns to lead the queue
  3. Rides in the pilot car and signals to drivers from the passenger seat
  4. Leaves the station while the pilot car is somewhere in the section
Show the answer

B. Holds traffic until the pilot car arrives and turns to lead the queue

With pilot car control, a flagger at each end holds vehicles until the pilot car has brought through the opposing queue and is ready to lead the next one. Releasing vehicles without the pilot car defeats the method.

How does the flag transfer method tell the flagger at the far end that the one-lane section is clear?

  1. The driver of the first vehicle sounds the horn at the far end
  2. The flaggers at each end switch stations after each queue
  3. The flagger counts vehicles and radios the total ahead
  4. The driver of the last vehicle carries a flag across
Show the answer

D. The driver of the last vehicle carries a flag across

In the flag transfer method the last vehicle in the group carries a red flag (or other token) to the flagger at the other end, who then knows that group is through. It is suited to short sections, usually no more than about a mile.
