Driving a tanker requires you to possess additional knowledge on top of your CDL. To pass the tanker vehicles endorsement exam, you will need to answer questions on tanker inspection, tanker safety, and Illinois traffic laws. Think you need some extra study help? Try our Free Illinois CDL Double/Triple Tanker Vehicles Practice Test! The 20-question multiple-choice test asks the same types of questions found on the DMV exam! The only difference is that we help you study by giving you the correct answers to questions you get incorrect! We used the official Illinois CDL Handbook to guide all our content and explanations. If you can pass our practice test with a score of 80% or higher than you will have proved your knowledge of tankers.

If you are going to spend money on registering for the DMV endorsement exam, then you should be sure that you will pass on the first attempt. Retakes are not free! Try out your knowledge with our Free Illinois CDL Tanker Vehicles Practice Test!
