Why does inspecting a combination vehicle take longer than inspecting a straight truck?

Pick an answer

1. Inspection time is identical regardless of vehicle configuration

3. It only takes longer because of the extra tires, with nothing else to check
4. There are more components to check, including the coupling, trailer landing gear, and separate trailer air and electrical systems
