How Many Questions Are on the Tennessee Permit Test? (2026 Guide)
Thirty multiple-choice questions is what the Tennessee Class D knowledge test hands you, and the other number I tell every student to remember is 24, because that's how many you've gotta get right inside the 60 minutes they give you. That's an 80% score. The exam is run by the Tennessee Department of Safety & Homeland Security, Driver Services, not a DMV. Your score appears right after you click submit.
Quick Answer: 30 Questions, 24 to Pass
Tennessee's Class D knowledge exam, the one for your learner permit, has exactly 30 multiple-choice questions. You must answer 24 of them correctly. That's the 80% threshold. Miss 7 questions and you fail that attempt. The Tennessee permit test passing score is 24 out of 30.
TN permit test questions come in English and Spanish. You take it at a Driver Services Center after a vision screening. The scoring is immediate. No waiting around for a mailed result.
The agency is the Tennessee Department of Safety & Homeland Security, Driver Services. People call it the DSD. Tennessee has no DMV. The Tennessee DMV permit test is actually a Driver Services exam.
The Four Sections on the Tennessee Knowledge Exam
The 30 questions pull from four content areas. Road signs and signals.
After the signs you've got the rules of the road, then a chunk on drugs and alcohol, and the last bit is safe-driving practices like how much room to leave when it's pouring on I-40.
Each section matters, but signs get heavy weight.
The questions come straight from the current Tennessee Comprehensive Driver License Manual. Not from random websites. I'd learn the shape and the color of every sign and not just what's printed on it, because plenty of my students can read a sign fine and still blank when it's a little picture on a screen. A yellow diamond means warning. Red with eight sides, well, I'm guessing you've already got that one down as a stop.
The question mix shifts between tests. One day you might see more right-of-way questions. Another day more alcohol-related ones. Study the whole manual.
I've had kids walk in knowing every sign and then get rattled by a run of questions about what alcohol does to your reaction time. It goes the other way too, like the grown adult who's been driving in Ohio for years and figures the signs will take care of themselves. You can't really predict which version of the test you're getting, so I wouldn't skip a chapter because it looks boring.
Passing Score Math: How Many You Can Miss
Here's the arithmetic. Take 80% of 30 and you land on 24, which I make people say out loud in my car until it sticks. That means you may miss no more than 6 questions. Miss number 7 and you're done.
There's no separate pass/fail split by section. It's one combined 30-question score. So yeah, in theory somebody could blank on the alcohol questions and still walk out with a permit as long as the rest of their answers hold up, but I wouldn't bet my Saturday on that.
Folks who've actually studied tend to wrap up somewhere around 20 to 30 minutes, and my guess is nerves eat most of that, so you'll have plenty of the hour left sitting there. But time pressure makes you misread. Two answers look right.
I want to see 27 or better on your practice runs, over and over, before you head down to the center, since one bad morning can easily knock three points off you.
I like to think of those six misses as a budget. Every question you guess on is spending out of it, so read each one all the way to the end, every answer choice included, before you tap anything. Your score shows up right after you submit, which means you won't be sitting at home all week wondering how it went.
Where and How You Take the Test
You take the test in person at any Tennessee Driver Services Center. You'll find them in Nashville and Memphis, and there are more out in Knoxville, Chattanooga and Clarksville if one of those is closer to your house. You'll do a vision screening first. Then the written test.
If you wear glasses or contacts, bring them, because the vision screening comes before anything else and that'd be a dumb way to lose a morning.
If you're 15, 16 or 17 there's an online version of the knowledge test you can use, as long as a parent or legal guardian is sitting right there with you. You use the Tennessee Proctor ID App. There's a QR re-authentication at the 30-minute mark. That's a specific detail.
This online option is only for the written knowledge test. Never the road skills test. When it's time for the road skills test you'll still be in a real car with an actual examiner next to you, and no app is getting you out of that.
That QR check at the 30-minute mark is the part that catches families off guard, so whoever's supervising needs to stick around and not wander off to start dinner.
I'd pull up tn.gov/safety the night before and look at your center's hours, plus whether you qualify for the online test at all. Hours change.
How to Pass the Tennessee Permit Test the First Time
Grab the current Tennessee Comprehensive Driver License Manual first, the actual one from the state and not somebody's summary of it. Not skimming. Reading. Then drill 30-question practice tests. Match the real format and timing.
Drivio's free Tennessee practice test at /tennessee helps you rehearse the exact question count and 80% threshold. That matters. Most practice tests online are shorter or longer than the real thing. You want 30 questions.
When you run a practice test, treat it like the real thing, so set a 60-minute timer and leave the manual closed. If the book's open next to you you're only reading with extra steps, and that score's gonna lie to you.
Whenever you miss one, flip back to that page in the manual and figure out why, and I'd spend the most time on signs and right-of-way since that's where my students lose the easy points.
I'd rather see you do twenty minutes after dinner every night than some four-hour marathon on a Sunday afternoon, and once you're clearing 90% pretty reliably, that's when I'd go ahead and head to a center.

Common Questions About Tennessee Permit Test Length and Scoring
How long does the test actually take? I'd plan on being done in under half an hour, though nobody's going to rush you if you want to use all 60 minutes.

How many practice tests should you take first? I'd say five at the very least, and you want 27 or up on those, though my nervous students usually keep going past that and feel a lot better for it.
Is the test only in English? Nope, you can take it in English or Spanish, so pick whichever one you actually read fastest in.
Do you find out right away if you passed? You do, the score comes up the moment you finish, and you'll know before you've left the Driver Services Center.
Please don't just memorize which letter was right on a practice test, go find the rule sitting behind each question instead. Then the test becomes straightforward.
