Is it permitted to transport a freight container while few of its twist locks are not secured?

1. Correct answer: Absolutely not.
2. Yes, but only when transporting short containers.
3. Yes, but only with the approval of a police officer.
4. Yes, when transporting a 40 feet container.

WhyIf not all the twist locks are secured, the container may not be carried. Neither its size nor a police permit changes that.
