- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 MI commercial driver's license manual
- Triple-checked for accuracy
- Updated for June 2025
Ready for a challenge? This Michigan CDL Tanker Vehicles Marathon is a new practice test that contains a compilation of all 96 questions that we have available for this MI endorsement. If you select a wrong answer, 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”. Give it your best shot!
