Wisconsin CDL Fees

Note: Additional fees may apply for endorsements and retesting. Always verify current fees on the Wisconsin DMV website before applying.

Knowledge Test Requirements

All CDL applicants must pass written knowledge tests to obtain a Commercial Learner's Permit (CLP) before taking the skills test. Required tests depend on your desired CDL class and endorsements:

Required Tests

The Wisconsin CDL Driver's Manual covers:

• Vehicle inspection procedures and safety
• Basic vehicle control and safe driving techniques
• Cargo handling and securement
• Air brake systems operation and inspection
• Passenger and school bus safety procedures
• Hazardous materials regulations and emergency response
• Federal and state traffic laws for commercial vehicles

Skills Test Requirements

After passing knowledge tests and completing required training, you must pass a three-part skills test:

Pre-Trip Inspection

Demonstrate your ability to inspect your vehicle for safety defects. You'll need to identify and explain various vehicle components and safety systems.
