When inspecting a combination vehicle, what aspect is typically more extensive than that of a straight truck?

When inspecting a combination vehicle, the inspection points are typically more extensive than those for a straight truck. This is because combination vehicles consist of multiple units, such as a tractor and trailer, which introduce additional components and systems that need to be evaluated.

For instance, the inspection will need to cover not only the engine and braking systems of the truck but also the coupling devices, the condition of the trailer, the functionality of the lights, and the overall integrity of the connection between the tractor and trailer. Each part of the combination vehicle may have its own set of inspection criteria to ensure safety and compliance with regulations.

In contrast, a straight truck has a simpler design with fewer components to inspect, leading to a more straightforward inspection process. Therefore, the depth and breadth of inspection points for combination vehicles require more thorough attention to detail, as they encompass both the towing vehicle and the towed unit.
