Read the first 7 Setup and Closure flashcards as text

  1. When setting up a temporary traffic control zone on a two-lane road, what is the correct order of device placement when working in the direction of traffic?

    Answer: Place devices starting farthest from the work area and moving toward it

    Devices should be placed starting farthest from the work area (upstream) and working toward it so workers are protected by already-placed devices.

  2. During closure setup, what is the primary purpose of the advance warning area?

    Answer: To alert drivers that they are approaching a work zone and must adjust their behavior

    The advance warning area alerts drivers to the upcoming work zone so they can reduce speed and prepare to merge or stop.

  3. What determines the minimum length of the transition area (taper) where lanes are closed?

    Answer: The posted speed limit and the width of the lane being closed

    Taper length is calculated using the posted speed limit and lane width, following the formula L = W × S (or W × S²/60 for speeds under 45 mph).

  4. A flagger is assigned to set up cones for a lane closure. How far apart should cones typically be spaced in the taper section?

    Answer: Equal to the posted speed limit in feet

    In the taper, cones are typically spaced at a distance in feet equal to the posted speed limit (e.g., 45 mph = 45-foot spacing).

  5. When is it appropriate to begin the closure setup process on a high-speed highway?

    Answer: During off-peak or low-traffic hours when possible, with proper approvals

    Closures on high-speed facilities should be set up during off-peak hours when possible to reduce exposure to high-speed traffic.

  6. What action should a flagger take if a road user drives through cones being placed during setup before the closure is complete?

    Answer: Alert the supervisor and move to a safe position immediately

    The flagger must move to a safe location immediately and alert the supervisor; personal safety always takes priority.

  7. Which component of a temporary traffic control zone is located immediately upstream of the work space?

    Answer: Buffer space

    The buffer space is a protected area immediately upstream of the work space that provides an extra margin of safety between traffic and workers.
