A securement system is defined as a method that uses which of the following?

A securement system is defined as a method that encompasses a variety of techniques and tools used to ensure cargo stability during transport. The term "securement system" can include blocking and bracing equipment, which are traditional methods to immobilize cargo by physically preventing movement. It also includes vehicle structure or securing devices, such as straps, chains, or tie-downs, which secure cargo directly to the vehicle.

The inclusion of "any of the above" as an option acknowledges that a securement system can integrate different methods and devices to achieve compliance with safety standards and regulations. This flexibility is essential because the optimal method for securing cargo can vary based on the type of cargo, its weight, and the vehicle being used.

In this context, the option stating that a securement system can be made up of different components showcases the comprehensive nature of securement practices that ensure cargo does not shift or come loose during transport, maintaining safety for both the cargo and other road users.
