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.

Which background color may be used on warning signs set up for a traffic incident such as a crash scene?

  1. Fluorescent blue
  2. Fluorescent pink
  3. Fluorescent green
  4. Fluorescent purple
Show the answer

B. Fluorescent pink

Signs in a traffic incident management area may use a fluorescent pink background with black legend, which sets them apart from planned road work. The other colors have no such use on warning signs.

How should the lights at a night flagger station or work area be aimed?

  1. Straight toward oncoming traffic, to get drivers' attention
  2. Straight up, so the light reflects down from above
  3. So they light the area without glaring into drivers' eyes
  4. Toward the flagger's face from the open-lane side
Show the answer

C. So they light the area without glaring into drivers' eyes

Floodlights must not produce disabling glare for approaching road users, flaggers or workers. Lights aimed at oncoming traffic blind drivers just as they reach the flagger.

Reference: MUTCD Part 6, flagger stations (2009 Edition Section 6E.08) and lighting devices (Section 6F.82)

What is the minimum width of a STOP/SLOW paddle?

  1. 12 inches
  2. 24 inches
  3. 30 inches
  4. 18 inches
Show the answer

D. 18 inches

The paddle must be at least 18 inches wide so drivers can read it from a distance. 24 inches is a common larger size, and is also the minimum size of a signal flag, but it is not the minimum for a paddle.

Reference: MUTCD Part 6, flagger hand-signaling devices (2009 Edition Section 6E.03)

Which of these is one of the abilities a flagger is expected to have?

  1. Recognizing dangerous traffic situations and warning workers
  2. Judging the speed of any vehicle to within 5 mph by sight alone
  3. Directing traffic at signalized intersections like a police officer
  4. Operating heavy equipment whenever traffic is light enough
Show the answer

A. Recognizing dangerous traffic situations and warning workers

A flagger must be able to spot a dangerous situation and warn the crew in time to avoid injury. Speed estimation to a set accuracy and police-style intersection control are not listed flagger abilities.
