Current Tennessee Knowledge Test Facts
Key Takeaways
- The Tennessee Driver License Knowledge Permit Test has 30 questions, a 60-minute limit, and an 80% passing score.
- Because 80% of 30 is 24, an applicant can miss no more than 6 questions.
- Tennesseans ages 15 through 17 may take the online knowledge test with a parent or legal guardian acting as proctor.
- Online applicants who fail must wait 24 hours before retesting, and Tennessee limits online knowledge testing to two attempts.
- The test is based on Tennessee Driver Services material, especially the Comprehensive Driver License Manual and current GDL rules.
Tennessee Knowledge Test Snapshot
The Tennessee Driver License Knowledge Permit Test is the written knowledge exam for a learner permit or first regular Class D license. Tennessee Driver Services lists the online version as a 30-question test with a 60-minute limit and a minimum passing score of 80%. That passing score matters in whole-question terms: 80% of 30 equals 24 correct answers, so 23 correct is still a failing score.
| Fact | Current Tennessee Rule |
|---|---|
| Test owner | Tennessee Department of Safety and Homeland Security, Driver Services Division |
| Format | 30 knowledge questions |
| Time limit | 60 minutes |
| Passing score | 80%, or 24 correct out of 30 |
| Online age window | At least 15 and no older than 17 |
| Online proctor | Parent or legal guardian using Tennessee Proctor ID |
| Online retest wait | 24 hours after a failed attempt |
| Online attempt cap | 2 online attempts |
The online option is not simply an unmonitored home quiz. Tennessee says the parent or legal guardian serving as proctor must use the Tennessee Proctor ID app, and the applicant must use a computer, laptop, or tablet rather than a cell phone. During the online test, the applicant must stay on the test screen. Notes, outside help, recording devices, and other electronic devices are not allowed.
The 30-minute authentication rule is also testable because it affects real test-day behavior. If the online test is still in progress at the 30-minute mark, the parent or legal guardian must re-authenticate through the app. If the applicant finishes, passes, or fails before 30 minutes, that mid-test authentication is not required. A long power or network interruption can turn into an automatic failure, so the applicant should test on a stable connection and charged device.
The in-person and online routes both lead back to Driver Services. Tennessee states that passing test confirmation is emailed and that applicants should print the online test receipt when possible. Tennessee also reserves the right to require a knowledge-test retake at a Driver Services Center, even after an online pass. That means the online pass is useful, but the Driver Services visit and document review are still part of the permit process.
What To Study
Use the Tennessee Comprehensive Driver License Manual as the core source. For this chapter, do not think of the test as a random national DMV quiz. Tennessee-specific details are fair game, including:
- GDL ages and permit restrictions
- Sign shapes, colors, signals, and pavement markings
- Right-of-way and lane-use rules
- Tennessee speed and school-zone facts
- Alcohol, drug, implied-consent, and under-21 BAC rules
- Test logistics such as 30 questions, 60 minutes, and 24 correct

Exam Focus
The safest way to remember the score is 30-60-24: 30 questions, 60 minutes, 24 correct. If a practice question says a candidate scored 23, do not round the percentage upward. Tennessee requires the minimum score, and 23 out of 30 is below 80%.
A Tennessee online knowledge-test applicant answers 23 of the 30 questions correctly. What is the result?
