TN CDL General Knowledge Exam Simulator 2024

At the Tennessee DMV, if you’re hoping to get a commercial driver’s license, you have to take a 50 question general knowledge exam. The questions are not just common sense, and you’ll want to get a copy of the official Tennessee Commercial Driver’s Manual, if you are going to have a chance to pass. You only have an hour to answer all the questions and if you miss more than 10 that is a failing grade (under 80%) and you’ll have to come back another day. In order to pass on your first trip, we suggest taking practice tests over and over again, until you know the material backward and forward. Our CDL General Knowledge practice exams are so close to the real thing that if you can pass the ones we offer, you can be confident that you will succeed at the Tennessee DMV. However, the test isn’t the only hurdle to face if you want your CDL. You also need to make sure you have documentation in order. For Tennessee, you need a Medical Examiner’s Certificate to prove that you are physically qualified to drive a commercial vehicle. These certifications last two years, unless you have a condition that the examiner believes should be monitored more closely, like high blood pressure. In addition, they require that you have proof of permanent legal residency or US citizenship. The simplest documents that fulfill this requirement are your social security card, birth certificate, or green card. In addition, they’ll want to see a valid current driver’s license. With all that and the confidence you need to pass the exam, you’ll be able to get in and out of the DMV in one trip. Start studying for the official exam with our practice test today!
