View All PlansCommercial driving theory is a complex subject that takes several weeks to master. As an aspiring commercial driver, you must become familiar with pre-trip inspections, special driving situations (such as night driving), rules of the road, and the most recent regulations. In Tennessee, the DMV oversees the licensing process and publishes the official Tennessee Commercial Driver License Manual (Tennessee CDL Handbook 2026). This comprehensive resource is available online for anyone considering a career in this field. You should read its contents multiple times to familiarize yourself with the basic aspects of commercial driving theory.
The official general knowledge exam consists of 50 multiple-choice questions. You must score 80% or higher to pass and get a Commercial Learner’s Permit (CLP). To help you prepare and achieve a passing score on your first attempt, we give you nonstop access to our Tennessee CDL Class B Practice Test. This intuitive tool can significantly boost your learning potential, especially when you use it alongside the official commercial driver license manual. Current for January 2026, this practice test reflects the latest updates brought by DMV rules or state law. (For the most up-to-date information, refer to the official TN DMV website.)

Always prioritize comfort when you’re studying for extended periods. After only one hour of studying, your eyes can get tired and feel dry. Optimize your learning environment to avoid the uncomfortable symptoms of eye strain. Lower your screen’s brightness, keep a safe distance from the screen, and use the slider from the test settings menu to modify the font size. If you have difficulty reading the text, you can make it bigger by adjusting the slider to your preference. Stay hydrated and take regular breaks to allow your mind to reset and regain focus.
You cannot learn commercial driving theory overnight, so we highly advise against rushing your learning phase. Focus on improving your knowledge one question at a time, and give yourself as much time as needed to fully understand the material. Whether it takes weeks or months, laying a strong foundation is essential for building your dream career.
