Questions (2)

1. When should a driver sign a vehicle inspection report?
  1. After every trip
  2. If noted defects are repaired ✓
  3. After each fueling

Answer: B. If noted defects are repaired

A driver should sign the vehicle inspection report if noted defects are repaired or certified as not needing repair. The handbook ties your signature to defect certification, not to completing a trip or stopping for fuel. It says a written inspection report may be required each day, and the motor carrier must fix any safety-related items listed and certify that repairs were done or were not needed. You sign the report only when defects were noted and that certification exists. The passenger-bus section repeats the same idea for reviewing the previous driver's report. That is why the signing point is after noted defects are repaired or cleared.
2. A driver should test the tractor protection valve by:
  1. Pulling the yellow, diamond-shaped knob.
  2. Releasing air with the brake pedal. ✓
  3. Unlocking the trailer doors.

Answer: B. Releasing air with the brake pedal.
