What type of vehicles can Class A inspection stations inspect?

Class A inspection stations in Missouri have the authority to inspect all types of vehicles, not just limited categories. This includes motorcycles, commercial vehicles, passenger cars, and trucks. The ability to handle a wide range of vehicles is crucial for ensuring that all motor vehicles on the road meet safety and emissions standards set by the state. This comprehensive licensing allows inspection stations at this level to serve various needs across the community, ensuring that different types of vehicles can be maintained for road safety.

The other options are incorrect since they limit the scope of vehicles that can be inspected by Class A stations, which is not reflective of their actual capabilities.
