Official signs, shapes, and meanings — the visual core of every handbook.
Start practicingThis is the official Massachusetts handbook published by Massachusetts Registry of Motor Vehicles (MassDOT RMV). It covers the knowledge commercial drivers need — vehicle inspection, safe driving, cargo, and the endorsement material for commercial licensing. Read it in sections, note the topics that are new to you, and then check what you have learned with the DriveReady practice tests below — they are original study questions written to the same manual material, not copies of the official exam.
