Written Knowledge (Permit) Test for A B & C CDLs
To earn your CDL learner’s permit in Louisiana, you must pass a written knowledge test that covers:
- State and federal trucking regulations
- Safe vehicle operation practices
- Vehicle components and air brakes
- Road signs and traffic laws
- Endorsements such as HazMat, passenger, tankers, and doubles/triples
This is the foundational CDL test in Louisiana before you can move on to behind-the-wheel skills evaluation.
