FREE OR CDL Tanker Vehicles Marathon 2018

Need a final study-spree? This Oregon CDL Tanker Vehicles Marathon is a super-challenging study tool that contains a mixture of all 40 questions that we have available for this OR endorsement. If you give an incorrect 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. As you work your way through the Marathon, you’ll discover that unlike the other Oregon CDL practice tests there are no explanations and no hints here. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Give it your best shot!
