A person shall not, and shall not permit anybody, to transport a freight container on his vehicle, unless:

1. The vehicle has an engine of at least 150 horse-powers.
2. The vehicle’s all up weight is at least 14,000 kg.
3. The vehicle has two spare tires.
4. Correct answer: It is indicated in the vehicle’s registration document that the vehicle is permitted to transport freight containers.

WhyA container may be carried only if the vehicle's registration document says it is permitted to carry containers. Engine power and spare tires have nothing to do with it.
