What the CDL permit tests cover
A commercial learner’s permit requires a vision exam and the knowledge tests for your class and endorsements. Most drivers take general knowledge, plus air brakes and combination vehicles when the vehicle needs them.
Because CDL rules are largely federal, most questions carry across states. State pages add licensing details for your agency.
