IMPORTANT: First watch the video for this test (top of this page), then take the following practice test. You should do well on just your first attempt. Repeat watching the video and taking this test until you get 100%. Next, move on to Tank Vehicles Test #2 and repeat this same routine. Then, take the Tank Vehicles DMV Simulated Exam, which has the same number of questions and the same time limit as your official state exam, and is different each time you take the exam.

This CDL Tank Vehicles test will prepare you to pass EVERY state’s DMV Tanker exam. A tanker endorsement is required if your vehicle needs a Class A or B CDL and you want to haul a liquid or liquid gas in a permanently mounted cargo tank rated at 119 gallons or more or a portable tank rated at 1,000 gallons or more. On the official DMV written exam, you must get at least 80% to pass.
