CDL Permit Class A exam requirements & cost
Straight from the certifying body — separate from what we charge for the study portal.
A CDL permit is required before you can schedule the behind-the-wheel skills test for a Class A commercial driver's license. Federal law (49 CFR Part 383) sets minimum standards, but each state's DMV or DPS administers the actual knowledge test, sets its own fees, and determines the minimum holding period before the skills test can be scheduled (commonly 14 days). Class A applicants operating air-brake-equipped combination vehicles need General Knowledge, Air Brakes, and Combination Vehicles sections at minimum; any endorsement (Hazmat, Tanker, Doubles/Triples) requires its own additional written section.
