Answer: C. 4
Each vehicle weighing more than 4,500 kg carried as cargo must be secured with at least four tiedowns.
Why this is the answer
The handbook separates vehicle cargo by weight. For vehicles under 4,500 kg, it calls for at least two tiedowns, front and rear. For heavy vehicles over 4,500 kg, it sets a minimum of four tiedowns, and each tiedown must have a working load limit of at least 2,268 kg. It also notes more tiedowns may be needed so their combined working load limit reaches at least 50 per cent of the cargo weight. That makes four the required base number for the heavy vehicles in the question.
Why the other answers are wrong
- A. 2 — Two tiedowns is the minimum the handbook gives for vehicles weighing less than 4,500 kg, not for vehicles over that threshold.
- B. 3 — Three tiedowns does not match the handbook's stated minimum of four for heavy vehicles over 4,500 kg.
- D. 5 — Five tiedowns is above the stated base minimum of four; extra tiedowns may be required based on the load's weight, but five is not the minimum the question asks for.
Remember it
Think of the weight line: under 4,500 kg starts at two tiedowns; over 4,500 kg starts at four.
