Under 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 2026). 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.
