Why must the spare tire and its carrier on a trailer be inspected?
- A.A loose spare can fall onto the roadway, and a missing or damaged carrier is itself a defect
- B.The spare adds braking power when mounted under the trailer
- C.Inspectors only check spares on the tractor
- D.A spare tire never works loose if it was tight last week
Correct answer
A. A loose spare can fall onto the roadway, and a missing or damaged carrier is itself a defect
Why
Anything that can drop from a moving trailer becomes a hazard for everyone behind it. The carrier, winch or chain, and the spare's security are legitimate inspection items.
