How Many Questions Are on the Tennessee Permit Test?
Tennessee's written knowledge test has 30 multiple-choice questions across four sections — road signs and signals, road rules, drugs and alcohol, and safe driving practices — and you need at least 24 correct (80%) within a 60-minute time limit.
The official test format
The explicit 60-minute time limit is worth knowing ahead of time — most states don't publish a specific time cap the way Tennessee does.
Applicants aged 15-17 can take the test at home, supervised by a parent or guardian through the Tennessee Proctor ID App; applicants 18 and older test in person at a Driver Services Center.
Because TDOSHS procedures and formats can change, always confirm the current requirements on the official Tennessee Department of Safety and Homeland Security website before your appointment.
How the questions are distributed by topic
The official test draws from the full Comprehensive Driver License Manual rather than any single area, which is why broad coverage matters more than memorizing a short list of facts.
Our free Tennessee permit practice tests cover 34 topic areas, including a dedicated set of sign-recognition questions, so you can see exactly which areas need more review.
How our practice tests are structured
Rather than mirroring the exact 30-question format, dmvwrittenexam.com splits its 146 original Tennessee permit questions into multiple 25-question practice tests, giving you far more repetitions than the official test alone would.
Each question includes an explanation and a source reference, so you learn why an answer is correct instead of just memorizing a letter.
