Free Tennessee CDL Permit Practice Test: General Knowledge 2024 | TN
Ready to get your Tennessee CDL? This practice test is your first gear on the road to becoming a commercial driver in the Volunteer State.
We’ve put 50 questions on this test, all from the very latest Tennessee CDL manual. From basic vehicle control to hauling hazardous materials -- you name it, and you’ll see a question about it. It is not about simply memorizing facts; it’s about knowing how to conduct yourself as a sober, responsible driver on Tennessee’s diverse roads, from the mountainous, curving highways of Appalachia to the bustling city streets of Nashville.
The state of Tennessee has some unique trucking laws you’ll need to be aware of. Ever hear of the “Move Over” law regarding utility vehicles? Or the distinct rules regarding the transportation of timber? We cover these and many more state-specific details so that you are fully prepared for transport in this state.
Every single question has an explanation. Don’t skip those -- they are gold for the understanding of the ‘why’ with each rule. Further, if you get stuck, there’s a hint feature to nudge you in the right direction.
This test is perfect whether you’re a first-timer or looking to renew your CDL. It’s also great for adding endorsements to your existing license.
Keep in mind, this is just practice. The actual test when you go to the DMV will be in a specific format and specific questions. But master this, and you will be in very good shape when that day comes.
Want more? Take a look at our complete CDL test preparation package. It includes specialty tests in all endorsements, from tankers to passengers.
Good luck, soon-to-be trucker. The highways of Tennessee are waiting for you!
