How should you load items on a truck to comply with regulations?

When loading items onto a truck, it is important to adhere to regulations that ensure safety and compliance with width restrictions. The correct answer states that loading must not exceed the vehicle's width. This is critical because exceeding the width can lead to several safety hazards, such as decreased control of the vehicle, increased risk of accidents, and potential violations of traffic laws.

Maintaining the vehicle's width also facilitates safer maneuvering through narrow roads, intersections, and parking areas, reducing the risk of sideswiping other vehicles or obstacles. Compliance with these regulations helps promote overall road safety and prevents the need for additional permits or legal issues that might arise from overloading.

The other options suggest scenarios that either exceed regulatory limits or are ambiguous about safe loading practices, which could compromise safety and contravene traffic regulations. Therefore, adhering to the correct guideline is essential for safe and lawful transport.
