Free Massachusetts CDL Permit Practice Test: General Knowledge 2025

The great state of Massachusetts has a diverse economy, with biotechnology, information technology, health care, finance, defense, and manufacturing among its key economic sectors, all of which can employ truck drivers. Bus drivers can benefit from the growing tourism sector in the state. For example, fall foliage bus tours are common.

The two most important highways for transporting goods into and out of the state are Interstate 90, which runs from Boston to Seattle, Washington; and Interstate 95, which runs from the Canadian border of Maine to Miami, Florida. Other important commercial routes are U.S. Route 3, which runs from the Canadian border of New Hampshire to Cambridge; and U.S. Route 6, which connects Cape Cod to other parts of Massachusetts and then goes westward to Bishop, California.

Unfortunately, commercial driving in Massachusetts can be challenging because of notoriously heavy traffic congestion. The Boston area is one of the most heavily congested areas in the country. Also, winters in the state can be tough, with heavy snow and ice making even travel on interstates treacherous.

To become a commercial driver in Massachusetts and benefit from its economic opportunities, you’ll need a Commercial Driver’s License (CDL). And one of the first important steps toward a CDL is to pass the official knowledge test for a Commercial Learner’s Permit (CLP). You’ll need a CLP to practice commercial driving (under supervision). You’ve likely been advised to study the official Massachusetts Commercial Driver License Manual (Massachusetts CDL Handbook 2025)? You ought to read it because the official knowledge test is based on it. However, you may want more help to pass the knowledge test than you’re getting from the manual. If so, you’ve come to the right place!

This free Massachusetts CDL permit practice test, one of several we offer, is based on the official state manual, just like the official knowledge test. It’s up to date as of October, 2025. There are 50 multiple-choice questions on such topics as cargo management, emergency preparedness, and pre-trip inspections. Unlike the official knowledge test, however, this practice test comes with our automated assistant.

Take your time, not only to improve your chances of passing the test but also to learn as much as you can from the experience.
