Wisconsin knowledge-test planning
Wisconsin DMV lists 50 questions for B/C General Knowledge, 20 for Class A Combined Vehicles, 25 for Air Brakes, 20 for Passenger, 20 for Doubles and Triples, 20 for Tank Vehicles, 30 for Hazardous Materials, and 25 for School Bus. DMV lists an 80% passing grade for knowledge tests. The test set you need depends on the vehicle and endorsements you seek.
Wisconsin CLP and skills-test steps
The state says a CLP is valid for 180 days and must be held for at least 14 days before skills testing. The CDL manual describes vehicle inspection, basic vehicle control and on-road driving as the three skills-test segments. Wisconsin uses authorized third-party examiners for skills testing. Verify your exact testing plan and current eligibility with DMV before scheduling.
Endorsements and training
Wisconsin uses endorsements for passenger transport, tank vehicles, hazardous materials, doubles and triples, school buses, and farm service. First-time CDL applicants, Class B-to-A upgrades, and certain H, P and S endorsement applicants generally need Entry-Level Driver Training before testing; exceptions apply. Consult the current Wisconsin manual, DMV requirements and FMCSA Training Provider Registry for your circumstances.
