What is an acceptable method for securing cargo in a commercial vehicle?

Using appropriate tie-downs or cargo nets is a fundamental method for securing cargo in a commercial vehicle. This practice ensures that the load remains stable during transit, preventing it from shifting or falling. Tie-downs are designed specifically to handle the forces that occur during acceleration, braking, and turns, thus providing safety for both the driver and other road users. Cargo nets can also help to contain and restrain the load, particularly when it's irregularly shaped or consists of multiple items.

In contrast, stacking items loosely in the vehicle would increase the risk of movement and potential load shift, which can lead to accidents. Relying solely on the weight of the cargo may not adequately secure the load, especially if the vehicle encounters sudden stops or turns, which could cause the cargo to shift and become hazardous. Using ropes without knots fails to provide a secure hold, as they may unravel or slip during transit, compromising safety. Each of these alternatives lacks the reliability and effectiveness of proper tie-downs or cargo nets.
