FREE SD CDL Double/Triple Trailers Marathon 2018

Need one final boost? This South Dakota CDL Double/Triple Trailers Marathon is a new practice test that contains a compilation of all 48 questions that we have available for this SD 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. 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”. Delivers some serious studying power! Do your best to complete this mega test!
