Massachusetts CDL Passenger Endorsement: Prohibited Practices Test 2026

Part of driving a bus well is knowing exactly what you must never do, and the Massachusetts passenger prohibited practices test spells that out for your 2026 CDL. This P endorsement drill covers the actions that endanger riders and can cost you the credential.

You will review passenger endorsement questions on fueling with people aboard, refueling in enclosed spaces, and the limits on talking or distractions while driving. The test also covers rules about towing or pushing a disabled bus with passengers on it, all things a responsible Massachusetts bus driver avoids.

Because the exam length differs from one state to another, use your Massachusetts CDL Manual to confirm the number of questions. Work through this prohibited practices quiz until the do-nots are unmistakable, and you will steer clear of the mistakes that fail applicants.
