Massachusetts CDL Manual 2026

How to use the Massachusetts CDL Manual

The RMV draws its 25-question knowledge test from the Massachusetts CDL Manual, and you need 72% to pass, which is 18 correct answers. Read the 192 pages once for coverage, then answer practice questions to find the rules that did not stick. Practice tells you what you do not know yet; the CDL Manual is where the rule is actually stated, in the words the state chose.

It is also the only source that settles an argument. When a practice answer and your instinct disagree, the Massachusetts CDL Manual decides it, and every explanation we write points back into it.
