Massachusetts CDL Practice Test
The content of the CDL knowledge test is federally standardized. FMCSA sets the testing standards in 49 CFR Part 383, and every state's CDL manual — Massachusetts's included — is based on the same national model. That's exactly why the practice questions on this page prepare drivers in Massachusetts the same way they prepare drivers everywhere else: you're studying the same general knowledge, air brakes, combination-vehicle, and endorsement material the Massachusetts test is required to cover.
What is specific to Massachusetts is the logistics around the test — the fees, how you schedule and where you go to test, the name of the licensing agency, and the official manual itself. Treat Massachusetts's official CDL manual as the final authority on those details, and use this page to drill the knowledge that the test is built on.

The process
Getting your CDL in Massachusetts
The steps below follow the federal minimums that apply in Massachusetts. Confirm Massachusetts's exact fees, forms, and scheduling in the official manual before test day.
Start with a commercial learner's permit (CLP). You pass the knowledge test(s) to get a CLP, then federal rules require you to hold it for at least 14 days before you can take the skills test in Massachusetts. Some states make you wait longer, so confirm locally.
Passing score is typically 80%. Most states, including Massachusetts, require 80% correct on each knowledge test. Skip the air-brakes portion and your CDL carries an air-brake restriction.
Endorsements are separate tests. Add the ones your job needs:
Hazardous materials. Knowledge test plus a TSA security threat assessment (a fingerprint-based background check).
Tank vehicles. Knowledge test on liquid surge, baffles, and hauling liquids or gases in bulk.
Passenger. Knowledge test plus a skills test in a representative passenger vehicle.
School bus. Requires the passenger endorsement, plus its own knowledge and skills tests.
Doubles / triples. Knowledge test covering the extra hazards of pulling double or triple trailers.

Massachusetts CDL practice test FAQ
Is this the official Massachusetts CDL test?
No. StudyItAll is a free study aid based on the federally standardized FMCSA knowledge topics that every state's CDL test is built on.

How many questions are on the Massachusetts CDL test, and what's the passing score?
Test length varies by the class and endorsements you're after, but the pass bar is consistent: most states, Massachusetts included, require 80% correct on each CDL knowledge test, so our practice and exam modes use the same 80% threshold. Confirm the exact question counts in Massachusetts's official CDL manual.
