How often should cargo be inspected during a trip?

Answer: B — Every 3 hours or 150 miles

Cargo should be inspected during a trip every 3 hours or every 150 miles to ensure that it remains secure and properly loaded. This frequent inspection is essential for maintaining safety on the road, as shifting cargo can affect vehicle handling and stability. Additionally, it helps to prevent damage to the load itself and ensures that no regulations regarding cargo transport are violated. By inspecting the cargo at these intervals, a driver can identify and address any issues, such as strap loosening or shifting loads, before they lead to larger problems. This practice is an important aspect of ensuring compliance with safety regulations and protecting both the driver and other road users. While other options may suggest less frequent inspections, they do not adequately address the need for regular checks to maintain safety and cargo security throughout the journey.
