CDL General Knowledge TestTransporting Cargo SafelyMedium
A driver is transporting a large, heavy machine that is bolted directly to the truck's frame. What type of securement is primarily being utilized?
- ABlocking and bracing
- BDirect securement
- CIndirect securement
- DChocking
Show answer & explanationAnswer & explanation
Correct answer: B. Direct securement
Direct securement involves tying down an article of cargo in a way that the securement device is attached directly to the cargo and prevents movement in a specific direction. Bolting cargo directly to the frame is a form of direct securement, as it physically restricts movement.
Why the other options are wrong
- A. Blocking and bracing use materials to fill spaces and prevent movement, not direct attachment.
- C. Indirect securement uses friction or other means to hold cargo, not direct attachment.
- D. Chocking is a specific type of blocking, usually for wheels or rounded objects.
