CDL Exam Requirements

Eligibility (typical)

• Valid auto license, proof of identity and residency as your state requires
• CDL medical certificate (DOT physical) on file with the state for most classes
• Pass the knowledge test(s) for the class and endorsements you want
• Hold a CLP for the waiting period (often 14 days) before the skills test
• 21 for interstate commerce; many states allow 18 for intrastate only
• H endorsement also requires a TSA security threat assessment

Always confirm current rules with your state. Federal standards are the floor; California, Texas, Florida and Georgia each book the exam at their own DMV / DPS / DHSMV / DDS.

Format

• Closed-book, multiple choice, one test at a time
• 80% on each test. Fail Air Brakes and you can still receive a CDL with an air-brake restriction
• Fail General Knowledge and you do not get the permit
• Fees, languages, and whether you can retest the same day are state decisions

After you pass the written tests

The state prints a CLP. You practice with a qualified CDL holder in the passenger seat, then schedule the skills test in a representative vehicle. Details: CDL permit.

Official starting point: FMCSA CDL.
