What is the required amount of securement in pounds for 12,000 pounds of cargo to prevent backward movement?

To determine the required amount of securement for cargo, particularly regarding backward movement, it's important to understand the principles of cargo securement as outlined in regulations such as those from the Federal Motor Carrier Safety Administration (FMCSA). The general guideline for calculating the securement needs for cargo states that you need to have a securement strength that is a percentage of the cargo's weight.

For preventing backward movement during transport, the requirement is typically calculated based on one-half of the cargo's weight. In this scenario, with 12,000 pounds of cargo, the calculation would be as follows:

12,000 pounds (weight of the cargo) multiplied by 0.50 gives you 6,000 pounds. This means that to effectively secure the cargo against backward movement, you would need at least 6,000 pounds of securement.

This demonstrates that for cargo weighing 12,000 pounds, the amount of securement required to prevent it from moving backward during transport is indeed 6,000 pounds. Thus, this reasoning confirms the validity of the correct answer.
