Which option is NOT a best practice for loading cargo onto a commercial vehicle?

The option that is not considered a best practice for loading cargo onto a commercial vehicle is placing heavier items on the passenger side for visibility. Proper load distribution is crucial for the stability and safety of a commercial vehicle. When heavier items are placed on one side, it can lead to an uneven weight distribution, which may affect the vehicle’s handling, braking, and overall balance.

For optimal safety, cargo should be loaded evenly and should not exceed the manufacturer's weight limits for axles. This practice also helps in balancing the vehicle so that it is easier to control and reduces the risk of rollover. Securement is vital as well, but ensuring a balanced load is fundamental to maintaining the vehicle's stability.
