The Wisconsin CDL Tanker test follows the AAMVA standard used by most states: 20 questions, with 16 correct answers (80%) needed to pass. A CDL learner's permit in Wisconsin costs $30 (Wisconsin Division of Motor Vehicles (DMV), Wisconsin Department of Transportation (WisDOT) fee schedule, June 2026).
Start the practice testHauling hazmat in a tanker? That’s the X endorsement
The X endorsement is the combined tank vehicle + hazardous materials endorsement (49 CFR 383.153). To earn it you pass both knowledge tests: the tanker test — knowledge-only, no skills test (49 CFR 383.93(c)) — and the hazmat test, which additionally requires a TSA security screening (49 CFR 383.71, part 1572).
Federally, a “tank vehicle” means tanks over 119 gallons individually and 1,000+ gallons combined (49 CFR 383.5) — if that’s your rig and the load is placarded, you need the X, not just the N.
