FREE DC CDL Pre-Trip Inspection Marathon

DC commercial driver's license
District of Columbia Commercial Driver's License.

Got a couple of hours to spare? This District of Columbia CDL Pre-Trip Inspection Marathon is a massive study tool that contains a combination of all 46 questions that we have available for this DC endorsement. If you make a mistake, 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 District of Columbia 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”. It might take some time, but you can do this!
