WI CDL Passenger Study Tips from Top Performers

1Memorize the Wisconsin P threshold: designed to carry, or actually carrying, 16 or more passengers including the driver.

3Know the CLP limits: 180-day validity, 14-day hold before skills testing, and no passenger transport except the narrow qualified-instructor/CLP-rider exception.
4Use number anchors: 80% passing score, 15 to 50 feet at railroad crossings, at least 50 feet before certain drawbridges, and 500 pounds total/100 pounds per class for allowed passenger-bus hazmat.
5Practice scenario questions that combine standee line, baggage, emergency exits, disruptive riders, disabled buses, brake-door interlocks, and crossing exceptions.
6If your test vehicle has air brakes, include Section 5 and understand how air-brake restrictions can affect passenger-vehicle authority.
