Free Online Tank Vehicles CDL Practice Test questions and answers to help you pass your state’s DMV Tanker Exam. There are 3 testing modes to help you prepare.


Want to haul tankers? A tank vehicles endorsement is required for certain vehicles that transport liquids or gases. Our Tank Vehicles practice tests will prepare you to get this CDL endorsement. The liquid or gas does not have to be a hazardous material. A tanker endorsement is only 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.

Test Instructions

  1. Download your state CDL manual and open up it up in another tab of your browser. Read it over, but you don’t need to try to memorize it!
  2. On this page, begin the first of our CDL practice tests in Classic Mode. See how well you do, but try not to stress out about any mistakes at this point.
  3. Next, switch to Practice Mode for intense preparation, complete with instant correct answers after every question and a CDL reference. 
  4. When you think you’re ready, take the exam! Each Exam Mode practice test is timed and you get your grade and results only after you’ve finished each test. This is very similar to the official state CDL written exams!
