Which vehicles are inspected at a Class M Station?

The selection of vehicles inspected at a Class M Station includes motorcycles, three-wheeled motor vehicle configurations, and trailers that are less than 20 feet in length and do not have air brakes. This is because Class M Stations are specifically designated for the inspection of vehicles that fall under lighter classifications and those that do not require the more stringent regulations applied to larger vehicles.

Motorcycles and three-wheeled motor vehicles are unique categories that necessitate specialized inspection criteria related to their design and safety standards. Trailers under 20 feet without air brakes are also included since they are considered lighter, more maneuverable vehicles that do not pose the same level of risk as larger vehicles with more complex brake systems.

In contrast, heavy trucks and trailers with air brakes require inspections that focus on different safety aspects due to their size and braking systems. RVs and converted buses, while larger and more complex, fall outside the Class M classification, as do standard passenger cars and multipurpose passenger vehicles, which are typically inspected in different classes that address their specific safety components and requirements.
