Maryland’s strategic location along the mid-Atlantic corridor makes it one of the nation’s most critical freight transportation hubs. Interstate 95 connects New York to Washington, D.C., while Interstate 70 links the Midwest to the East Coast. These routes carry heavy commercial traffic through the Old Line State. Moreover, the port of Baltimore ranks among America’s busiest ports, further supporting the state’s major industries.
If you are considering a career in commercial driving, you shouldn’t delay taking the first step. There’s an increasing demand for Class A CDL holders who are able to operate combination vehicles. To legally drive semi-trucks and tractor-trailers, you must complete the licensing process. The Motor Vehicle Administration (MVA) requires all applicants to pass the official combination vehicles knowledge test (plus additional requirements), which covers topics such as coupling and uncoupling procedures, jackknife prevention, and commercial driving regulations. A minimum score of 80% is required to pass, leaving little room for error.
