Fasten your seat belt for one last wild ride of studying! This South Dakota CDL Tanker Vehicles Marathon is a monster of a practice test that contains a compilation of all 96 questions that we have available for this SD endorsement. If you make a mistake, we’ll remember that question and will display it to you again at the very end of the Marathon until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. It might take some time, but you can do this!

Make sure you're ready for the Tanker endorsement with our specialized tanker endorsement test collection, and solidify your knowledge by exploring our thorough Tanker endorsement guide.
