Tennessee CDL Practice Test

Free practice questions for the Tennessee commercial driver license written exams — general knowledge, air brakes, combination vehicles, and every endorsement.

Tennessee's learner's permit test is a crucial milestone for new drivers seeking to develop their driving skills under supervision. The Tennessee Department of Safety and Homeland Security administers the knowledge test that all prospective drivers must pass before obtaining a learner's permit. Whether you choose to test in person at a Driver Services Center or online through the Tennessee Proctor ID App if you're between 15 and 17 years old, understanding the test requirements and format will help you prepare effectively. Tennessee offers accessible testing options including the ability for teen drivers to take the exam online at home with parental supervision, making the process more convenient for young drivers throughout the state.

About this section of the Tennessee test

Tennessee's Commercial Driver License (CDL) tests include separate knowledge exams for different classes and endorsements (such as tanker, hazmat, and passenger vehicle endorsements). The CDL knowledge test must be taken in English only, as federal regulations require commercial drivers to read and speak English sufficiently. Each test section is scored separately, so you only need to retake sections you didn't pass.
