  1. When a tree crew is working adjacent to a two-lane road with no shoulder, what is the MINIMUM recommended buffer distance between the work zone and active traffic lanes per ANSI Z133?

    Answer: 10 feet

    ANSI Z133 recommends a minimum 10-foot buffer between the work zone and the nearest active traffic lane when no shoulder exists.

  2. A ground worker notices a limb is about to fall in an unexpected direction. The FIRST action should be to:

    Answer: Shout a warning to all personnel and move to the pre-designated escape route

    Immediate audible warning and movement to the pre-planned escape route is the priority to protect all workers from the unexpected hazard.

  3. Which type of traffic control device is used to guide drivers through a temporary work zone by physically separating travel lanes from the work area?

    Answer: Channelizing devices (cones, drums, barriers)

    Channelizing devices such as cones, drums, and barriers physically separate and guide traffic through or around a temporary work zone.

  4. Under the MUTCD, the minimum distance for an advance warning sign on a road with a 45 mph speed limit in a typical urban environment is approximately:

    Answer: 350 feet

    The MUTCD prescribes approximately 350 feet advance warning sign spacing for a 45 mph urban roadway to give drivers adequate reaction time.

  5. A crew is chipping brush alongside a residential street. Which PPE item is MOST critical to prevent hearing damage from the chipper?

    Answer: Hearing protection (ear plugs or muffs)

    Wood chippers produce noise levels commonly exceeding 100 dB, making hearing protection essential to prevent noise-induced hearing loss.

  6. When positioning a wood chipper on a jobsite, it should be oriented so that the discharge chute:

    Answer: Faces away from workers, the public, and any structures

    The discharge chute must be aimed away from workers, bystanders, and structures to prevent injury from ejected material.

  7. When a flagger in a tree work zone signals 'STOP,' drivers who have already entered the taper area should:

    Answer: Stop immediately and remain stopped until the flagger signals to proceed

    Once a flagger displays STOP, all vehicles must halt and wait for the flagger's signal before proceeding, even if already in the taper.
