Massachusetts CDL General Knowledge: Driver Fitness Test 2026

Your logbook is as important as your license, and this Massachusetts CDL driver fitness and hours of service test covers the federal duty limits and health rules every trucker lives by in 2026. You will answer questions on daily and weekly driving caps, mandatory rest breaks, medical certification, and recognizing when fatigue makes you unfit to continue.

These items track the driver-fitness and hours-of-service guidance in the Massachusetts commercial driver license manual, which mirrors FMCSA regulation. Expect prompts on the 11-hour and 14-hour rules, the 30-minute break requirement, and why falsifying a record of duty status can end a driving career fast.

This fitness and hours drill is only one part of the broader Massachusetts CDL general knowledge exam, which asks 50 questions and sets the passing line at 80 percent, or 40 correct. Rehearse it until the limits are second nature, then keep cycling through your remaining practice sets before you test.
