View All PlansUnder Massachusetts law, standard commercial vehicles must be no more than 102 inches wide without a special oversize permit. The colonial-era infrastructure includes many historic roads, bridges, and tunnels that may restrict the passage of oversized combination vehicles. As a commercial driver, you must carefully plan your route at the beginning of your shift.
Combination vehicles are the backbone of the nation’s freight network, but they can be difficult for beginners to operate. That’s why in your learning phase, you will study commercial driving theory and its various aspects. After passing your theory exams and earning your CLP (Commercial Learner’s Permit), you can get behind the wheel of an 18-wheeler and gain real-life driving experience.
The Registry of Motor Vehicles (RMV) publishes the official Commercial Driver’s License Manual (Massachusetts CDL Handbook 2025). We recommend reading its contents multiple times during your learning phase so that you won’t miss any important details. To ensure you get a passing score on your theory exams, you can use our practice tests to evaluate your knowledge before exam day. Our Free Massachusetts CDL Permit Practice Test will teach you general commercial driving theory. Check it out and incorporate it into your study routine.
This Massachusetts CDL Combination Vehicles Practice Test consists of several multiple-choice questions similar to those you will encounter in the official combination vehicles knowledge exam. Designed to boost your learning potential, this intuitive tool can be accessed anytime, anywhere in the world.
To reflect the latest updates brought by RMV rules or state law, we keep this practice test up to date (most recently updated for December 2025). You will always practice with the latest version, but we recommend visiting the official RMV website for the most up-to-date information.
The most experienced truck drivers were once beginners. With consistency and perseverance, you can also join their ranks. Start your training today and improve your knowledge one question at a time. Within a few weeks, you’ll be ready to ace your theory exams on your first attempt.
