How would we attach a freight container to the vehicle’s loading surface?
- With steel cables – if a screw anchor (twist lock) is absent.
- With the walls of the loading surface.
- Correct answer: With a screw anchor (twist lock) only.
- With two independent chains, each connected to the loading surface.
Why this is the answer
The correct answer in the official bank: With a screw anchor (twist lock) only.
A freight container must be secured to the loading surface only with twist locks, which lock into the container's corner fittings and hold it firmly. Steel cables, chains or the walls of the loading surface are not an acceptable substitute, even when twist locks are missing, so a container should not be carried on a vehicle without them.
