What is the classification for trailer vehicles in Maryland?

In Maryland, trailer vehicles fall under the classification of Class G. This classification specifically pertains to trailers and certain types of vehicles designed to be towed by motor vehicles. Understanding this classification is crucial for proper registration and compliance with state laws, as it ensures that the correct requirements are met for size, weight, and safety.

The other classifications pertain to different vehicle types: Class E typically relates to standard passenger vehicles, while Class J often refers to farm vehicles. Class A can relate to larger combinations of vehicles, such as those used for commercial purposes, which are not the focus for standard trailer classifications. Thus, Class G is the appropriate designation for trailers in Maryland, making it the correct answer to the question.
