Free CDL Practice Tests
UniPrep2Go’s CDL path groups free timed readiness checks for commercial driver general knowledge plus endorsements such as air brakes, combination vehicles, doubles/triples, tankers, hazmat, passenger, and school bus themes. Each mock scores by topic so you can see whether vehicle systems, cargo securement, or endorsement rules are the weak link before a state DMV sitting.

Which CDL practice tests belong here?
Start with general knowledge if you are new to Class A/B prep, then add endorsement mocks that match your license goal. Air brakes and combination vehicle checks matter for most tractor-trailer paths; hazmat, passenger, and school bus are endorsement-specific. UniPrep2Go mocks are independent diagnostics — confirm your state’s handbook edition and knowledge-test vendor rules before exam day.
How to use these free CDL practice tests
Sit one timed session under quiet conditions, read the topic report, and drill missed domains daily with the linked Anki deck when available. Pair every study block with your official CDL manual — flashcards do not replace the state handbook or skills-test practice.
