About the Maryland Combination Vehicles Test
Topics Covered
- ✓Coupling and uncoupling procedures — Maryland examiners want the full sequence, especially when you're working in tight spots like the Port of Baltimore loading docks.
- ✓Jackknife causes and prevention — on I-95 in stop-and-go traffic, a jackknife can happen fast. You need to know what triggers it and how to stop it.
- ✓Off-tracking and trailer swing — the Bay Bridge's 4.3-mile span has narrow lanes, and a long trailer cuts corners differently. Learn to compensate.

📘 Study Tips & State Info
The MVA test is 20 questions, 80% to pass. Most people miss points on the coupling sequence. The examiners want the exact order — from checking the fifth wheel to connecting the air lines and securing the glad hands. Don't skip a step. Memorize the sequence like a checklist.
Another area that trips up Maryland drivers is off-tracking. When the manual says 'longer trailers cut corners more sharply,' picture the Bay Bridge or the Inner Harbor tunnels. That's where you'll feel it. Also, know how to prevent a rollover on a curve — the MVA loves asking about speed and load distribution.
Finally, practice with our timed tests. The real test gives you 25 minutes. If you can finish our practice in 20 with 90%, you're ready. Don't cram the night before. Study the manual, take the practice tests, and think about how each rule applies to the roads you'll actually drive in Maryland.
The Maryland Motor Vehicle Administration (MVA) handles all CDL testing. You'll take the Combination Vehicles test at any MVA office that offers CDL services — Glen Burnie, Bel Air, Frederick, Waldorf, and others. You must make an appointment for CDL written tests. Walk-ins are not guaranteed a slot.
Bring your valid driver's license, proof of U.S. citizenship or lawful presence, and a current Medical Examiner's Certificate (DOT physical). The test fee for the endorsement is $30 (subject to change — check the MVA website). You must pass the General Knowledge test before you can take any endorsement test.
Maryland also requires a skills test for the actual CDL. The Combination Vehicles written test is just the first step. Pass this, and you'll move on to the pre-trip inspection, basic controls, and road test. The road test includes real Maryland roads, so expect traffic, hills, and maybe the Bay Bridge if your examiner takes you that way.
About the Maryland Combination Vehicles Test
The Maryland Combination Vehicles endorsement is required for every Class A CDL applicant in the state. If you plan to drive tractor-trailers, doubles, or any rig that hooks a trailer to a tractor, you need this test. Maryland roads aren't easy — you've got the tight ramps of the Capital Beltway, the steep grades on I-70 west of Hagerstown, and the constant traffic on I-95 between Baltimore and D.C. Your trailer handling skills have to be sharp from day one.
This test covers coupling and uncoupling, trailer stability, jackknife prevention, and the unique physics of articulated vehicles. Maryland follows the federal CDL standards, so the content matches what you'll see anywhere. But the MVA expects you to apply that knowledge to real Maryland conditions — like the crosswinds on the Bay Bridge or the tight turns at the Port of Baltimore.
The written test is 20 multiple-choice questions. You need 16 correct to pass — that's 80%. The MVA gives you about 25 minutes. Our practice test mirrors that time limit so you know what to expect. Don't walk in cold. Study the Maryland CDL manual and run through these questions until the answers feel automatic.
