Wisconsin CDL Passenger Endorsement: Prohibited Practices Test 2026

Certain actions are flatly prohibited for a Wisconsin CDL passenger endorsement holder in 2026, and this practice test focuses on knowing exactly where those lines sit. Expect questions on carrying items that block the aisle or exits, transporting hazardous materials without proper authorization on a passenger vehicle, and fueling with riders aboard.

You will also see items on smoking rules, standing beyond a marked line, and towing or pushing another vehicle while carrying passengers, each a specific violation tested on the CDL passenger endorsement exam. These are memorization-heavy questions, and Wisconsin DMV expects a bus driver to know them cold, not to reason them out on the spot.

Pair this quiz with the on-the-road and loading tests in this Wisconsin passenger set, since several prohibited practices connect directly to loading and driving decisions. The Wisconsin CDL Manual lists every prohibited action explicitly; treat this practice test as your recall check against that list.
