The Texas driver's license written knowledge test contains 30 questions. To pass, you need to answer at least 21 correctly — that's a 70% passing score. Those two numbers are the starting point for understanding what you're actually walking into when you sit down at a Texas DPS testing station.
But the question count alone doesn't tell the full story. The structure of the test, what it covers, how many attempts you get, and whether you're even taking the standard 30-question version all depend on factors specific to your license type and situation.

The test is administered at Texas Department of Public Safety (DPS) driver's license offices. It is computer-based at most locations. Questions are drawn from the Texas Driver Handbook, which covers traffic laws, road signs, right-of-way rules, safe driving practices, and related topics.
The 30 questions are drawn from several subject areas, not one narrow topic. Expect questions on:
The Texas Driver Handbook is the primary study source. The test is designed to reflect real situations drivers encounter, not trick questions or obscure statute references.
Not exactly. The 30-question format applies to standard Class C passenger vehicle licenses — the type most people are seeking. However, other license classes and endorsements involve separate or additional testing:
The 30-question number is firmly tied to the standard Class C license. Anyone applying for something outside that category should verify the specific test format that applies to their license class.
Texas allows retakes if you don't reach the 21-question threshold, but there are limits and waiting periods involved. Failing once doesn't mean you walk in the next morning and try again.
The exact number of retakes allowed and the waiting period between attempts can vary based on your age, how many times you've already tested, and other factors. Generally, applicants who fail are required to wait a set number of days before retesting, and repeated failures may trigger additional requirements before another attempt is permitted.
📋 Knowing the rules around retakes matters if you're on a time-sensitive timeline — such as needing a license before a job start date or an out-of-state move.
For applicants under 18, the knowledge test is one step in Texas's Graduated Driver Licensing (GDL) program. Teens applying for a learner's permit (called a learner license in Texas) must:
After holding the learner license for a minimum period and completing required supervised driving hours, teens return for a driving skills test before advancing to a provisional license and eventually a full license.
The written test is the same 30-question format regardless of age — but what happens before and after it depends heavily on whether you're under 18 and where you fall in the GDL process.
If you're moving to Texas with a valid out-of-state license, you may not have to take the knowledge test at all. Texas generally waives the written and skills tests for applicants with a valid license from another U.S. state — but this depends on your specific situation, whether your prior license is current, and what class of license you're transferring.
🔄 Out-of-state CDL holders face additional federal verification steps and may have different requirements than standard Class C applicants.
Thirty questions. Twenty-one to pass. Those numbers aren't moving. What changes is whether you're taking that specific test, how prepared you need to be for it, how many attempts you'll have, and what comes before and after it in your particular licensing path.
Your age, license class, driving history, and whether you're coming in as a first-time applicant or transferring from another state all shape the experience around that 30-question test — even if the test itself stays the same.
