CDL General Knowledge TestTransporting Cargo SafelyHard
A driver is inspecting a sealed trailer containing general freight. Which of the following is an acceptable method for determining if the cargo is properly secured without breaking the seal?
- ARequesting the shipper to break the seal for inspection.
- BObserving the trailer's suspension and overall stance.
- CShaking the trailer vigorously to listen for shifting.
- DOpening the trailer doors partially to peek inside.
Show answer & explanationAnswer & explanation
Correct answer: B. Observing the trailer's suspension and overall stance.
Observing the trailer's suspension and overall stance can give clues about cargo distribution and potential shifting. For example, if one side is significantly lower, or the trailer appears to be leaning, it could indicate an improperly balanced or shifted load. This is a non-invasive method for a sealed trailer.
Why the other options are wrong
- A. While possible, requesting the shipper to break the seal is usually a last resort and often not an 'acceptable method' for routine driver inspection without specific reasons.
- C. Shaking the trailer is impractical, potentially damaging, and unsafe, and does not guarantee detection of all shifting.
- D. Opening sealed trailer doors is generally prohibited for drivers without authorization, as it breaks the seal.
Inspecting Sealed Cargo
Methods to assess cargo securement and balance in a sealed trailer without opening it.
- Visual cues are primary for sealed trailers.
- Look for uneven suspension or leaning.
- Listen for unusual sounds during movement.
Memory trick: Look, listen, feel — don't break the seal.
