WI CDL General Knowledge Exam Simulator 2025

When looking to earn money driving a commercial vehicle in Wisconsin, you’ll need to follow some specific steps to get your Commercial Driver’s License. First you’ll need to take care of the documentation. The Wisconsin DMV requires that you provide a Medical Examiner’s Certificate that proves you are physically qualified to drive a commercial vehicle. Also known as a DOT Card, the certificate can’t be picked up from just any medical professional, you have to get it from a licensed medical examiner that is listed by the Federal Motor Carrier Safety Administration (FMCSA) National Registry. Then, you also need to bring a current valid driver’s license and proof of US citizenship or permanent legal residency. For this last document, a green card, social security card, or birth certificate will work well. Only once you have all that together will they even let you get to the test. The general knowledge test is a 50 question multiple choice exam. While you may think that the hour they give you is plenty of time for a test like that, it can be tricky and if you get over 10 wrong then you fail the exam. Failure means you have to come back to the DMV another day as you can’t take the test more than once in one day. That’s a serious hassle and one you can avoid by studying for the test first. To do this properly, get your hands on an official Wisconsin Commercial Driver’s License Manual. While all the facts you need are arranged in there, it’s difficult to really get your mind around the test without checking out some practice exams. That’s where we come in. Our CDL General Knowledge practice tests show you how the information will be applied in question form with text that is very similar, if not identical, to the real thing. After you can ace a few of our Commercial Driver’s License practice tests you can go to the DMV with the confidence that you will pass on your first outing.
