Cargo that can shift should have at least how many tie-downs?

Cargo that has the potential to shift during transit requires a minimum of two tie-downs to ensure its stability and safety. Utilizing two tie-downs creates a more secure restraint system that reduces the likelihood of movement, which is crucial for preventing accidents or load shifts that could endanger the driver, other road users, and the cargo itself.

The rationale behind having at least two tie-downs is that they help to distribute the force more evenly across the load. This can prevent one side from being overloaded or, conversely, under-supported, which can lead to instability. Each tie-down contributes to holding the cargo in position, and having two allows for crosswise or diagonal configurations, which provide better overall restraint.

The other options suggest fewer tie-downs, which would not adequately secure cargo that is capable of shifting during transport. A single tie-down may not provide enough force to keep the load secure, especially in the event of sudden stops, turns, or changes in speed. Using three or four tie-downs may offer extra security, but the requirement mandates a minimum of two to meet safety standards and regulations.
