The Tanker Vehicles (N) endorsement authorizes you to operate vehicles that transport liquid or gaseous cargo in individual containers each holding more than 119 gallons and with a total combined capacity of at least 1,000 gallons. You can add this endorsement to your Class A or Class B CDL (Commercial Driver’s License) by passing a specialized knowledge exam.
Your knowledge of liquid surge, special driving situations, and the safe operation of tanker vehicles will be evaluated on the official tanker vehicles knowledge exam. Consisting of 20 multiple-choice questions, this exam is based on Section 8 (Tank Vehicles) of the official Commercial Driver’s Manual (Wisconsin CDL Handbook 2025). You must answer all questions and score 80% or higher to pass, leaving little room for error.
This Wisconsin CDL Tanker Vehicles Practice Test is designed to help you achieve a passing score on your first attempt. Like many of our practice tests, this one has no time limit. You can complete it at your own pace without rushing. If you make a mistake, we will immediately point it out. The detailed explanation will help you turn mistakes into learning opportunities and strengthen your understanding of tanker-specific concepts. For future reference, you should note this feedback in a notebook or notebook app.
