About the Massachusetts General Knowledge Test
Topics Covered
- ✓Vehicle inspection procedures — Massachusetts examiners watch you do a pre-trip on a real truck, so you need to know every light, tire, and brake component cold.
- ✓Basic vehicle control, including turning and backing — with Boston's tight streets and narrow loading docks, you can't afford to guess.
- ✓Shifting and gear selection — hauling up the grades on I-495 or down into the Berkshires demands knowing when to drop a gear.

📘 Study Tips & State Info
Massachusetts RMV examiners are sticklers for pre-trip inspection. They want you to actually touch each component and say the condition out loud. Don't just memorize a script — understand why a cracked brake hose is dangerous. On the written test, expect at least 10 questions on inspection procedures.
The manual has a section on driving in winter weather that's thicker than most states'. Read it twice. Massachusetts gets real snow, and the RMV expects you to know how to handle it. Questions about stopping distance on ice, using tire chains, and when to pull over are common. Also study the section on highway driving — the Mass Pike, I-93, and Route 128 have heavy traffic and weird merges. They'll test you on how to enter and exit highways safely.
One more thing: the RMV sometimes includes questions about railroad crossings and emergency vehicles. Massachusetts has a lot of at-grade crossings, especially west of Worcester. Know the rules for crossing with a commercial vehicle. And never, ever cut off an ambulance — that's a real fail on the road test.
The Massachusetts RMV handles all CDL testing. You'll need to make an appointment online at Mass.Gov/RMV for the written knowledge test. The fee is $40 for the learner's permit application, which includes the General Knowledge test and one endorsement test. If you fail, you can retake it the same day for an additional $20, but only if the branch has computer availability — and they often don't.
Full-service RMV branches that offer CDL testing are in Boston (Haymarket), Worcester, Springfield, Fall River, and Plymouth. There are also smaller satellite locations in Greenfield, North Adams, and Hyannis, but they have limited hours. Bring your Social Security card, proof of Massachusetts residency (two documents), and a valid Medical Examiner's Certificate (DOT physical). If you don't have the physical yet, you can get the permit but you won't get the license until you submit it.
Massachusetts has a unique requirement: you must complete a state-approved CDL training program or have at least 20 hours of behind-the-wheel experience with a certified instructor before you can take the road test. The written test is the first step, so study hard and pass it the first time.
About the Massachusetts General Knowledge Test
The Massachusetts General Knowledge test is the foundation for every commercial driver's license in the state. Whether you're hauling seafood from New Bedford, concrete from Worcester, or freight out of the Boston Logistics Park, you have to pass this before anything else. The test covers vehicle inspection, basic control, shifting, backing, and the Massachusetts-specific rules about driving in snow and heavy traffic.
MassDOT runs the RMV, and they follow the federal CDL standards closely. But they also add their own flavor — expect questions about driving on the Southeast Expressway (I-93) during rush hour, handling the rotary at the Sagamore Bridge, and what to do when a nor'easter drops a foot of snow overnight. The test is 50 multiple-choice questions, and you need 40 correct (80%) to pass. You get 60 minutes.
Every Class A, Class B, and Class C applicant takes this test. Even if you're only getting a learner's permit, this is your first hurdle. The RMV administers it at their full-service branches — the ones in Boston, Worcester, Springfield, and Fall River are the busiest. Make an appointment online or you'll wait hours.
Our practice test mirrors the real thing. Same question bank, same format, same time limit. Use it to find your weak spots before you pay the $40 fee and sit down at that RMV computer terminal. No surprises.
