FREE SD CDL Combination Vehicles Marathon 2018
Need one final boost? This South Dakota CDL Combination Vehicles Marathon is a monster of a study tool that contains a combination of all 79 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. As you work your way through the Marathon, you’ll see 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!
