  1. When inspecting the coupling system on a combination vehicle, what does it mean if you can insert the fifth wheel safety latch (lock handle) while the kingpin is engaged?

    Answer: The latch is defective and the vehicle should not be driven

    If the safety latch can be inserted after coupling, the locking mechanism is defective and the trailer could separate from the tractor.

  2. During a pre-trip inspection, you find a tire with a bulge on its sidewall. What should you do?

    Answer: Take the vehicle out of service immediately

    A bulge indicates internal structural damage that could cause a blowout; the tire must be replaced before the vehicle is driven.

  3. What is the correct way to check that your trailer emergency brakes are working during a pre-trip?

    Answer: Pull out the red trailer air supply valve and tug on the tractor

    Pulling the red trailer air supply valve deploys the trailer emergency brakes; you then test by tugging the tractor to confirm the trailer does not roll.

  4. When inspecting the suspension system, which of the following defects requires taking the vehicle out of service?

    Answer: A missing leaf spring

    A missing leaf spring significantly compromises load-bearing capacity and vehicle stability, making it an out-of-service defect.

  5. When performing a pre-trip walkaround, how many complete circles around the vehicle are required?

    Answer: One complete circle

    The pre-trip inspection is performed as one systematic walkaround starting at the driver's door and moving in one direction around the entire vehicle.

  6. What should be the condition of the cargo securement when performing a pre-trip on a loaded flatbed?

    Answer: All cargo must be properly blocked, braced, tied, or chained

    The driver is responsible for ensuring all cargo is properly secured before departure regardless of trip length or who loaded the vehicle.

  7. During a pre-trip inspection, you check the windshield and find a small crack in the lower corner outside the driver's line of sight. What is the correct action?

    Answer: The vehicle may be driven but the crack must be reported on the DVIR

    A crack outside the critical driver visibility zone is a reportable defect on the DVIR but does not automatically take the vehicle out of service.
