FREE SD CDL Pre-Trip Inspection Marathon 2018

Ready for a challenge? This South Dakota CDL Pre-Trip Inspection Marathon is a monster of a practice test that contains a mix of all 46 questions that we have available for this SD endorsement. If you give an incorrect answer, we’ll remember that question and will display it to you again at the end of the exam 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 notice that unlike the other South Dakota 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!
