The Texas knowledge test covers road rules, signs, and safe driving

The Texas knowledge test is a written exam you take at a Department of Public Safety (DPS) office to show you understand traffic laws and road safety. You answer questions about what road signs mean, how to handle different driving situations, and the rules of the road in Texas. The test has 30 multiple-choice questions, and you need to answer at least 21 correctly to pass.

This test is required whether you are getting your first license, renewing after it has expired for more than two years, or moving to Texas from another state. If you fail, you can retake it the same day or come back another time — there is no waiting period between attempts in Texas.

Key Takeaways

  • The Texas knowledge test has 30 multiple-choice questions, and you must answer at least 21 correctly to pass.
  • You can take the test in English or Spanish at any DPS office, and the test covers road signs, traffic laws, and safe driving practices specific to Texas.
  • You have up to three hours to complete the test, though most people finish in 30 to 45 minutes.
  • If you fail, you can retake the test the same day or return another time without a waiting period.
  • The Texas Driver Handbook is the official study material and covers everything the test will ask about.

What the Texas knowledge test covers

The test focuses on three main areas: road signs and their meanings, traffic laws and rules of the road, and safe driving practices. You will see questions about speed limits, right-of-way rules, parking, lane changes, and how to respond to traffic signals and signs. The test also includes questions about what to do in bad weather, how to handle an accident, and the rules for sharing the road with pedestrians and cyclists.

Texas-specific rules appear on the test, such as the state's laws about headlights, seat belts, and child safety seats. You may also see questions about distracted driving, following distance, and how to drive safely around emergency vehicles. The test does not ask about your personal driving history or require you to know local city ordinances — it sticks to state traffic laws and general road safety.

How to study using the Texas Driver Handbook

The Texas Driver Handbook is the official study guide published by DPS and is available free on the DPS website as a PDF read. You can also request a printed copy at any DPS office. The handbook contains all the information covered on the knowledge test, organized by topic, so you can study the areas you find hardest first.

Most people study the handbook by reading it straight through, then going back to review sections they found confusing. Others focus on the road signs section first, since sign recognition is a large part of the test. You can also find practice tests online through the DPS website or third-party study sites — these let you see the types of questions and the format before test day.

Taking the test at a DPS office

You schedule your test appointment online through the DPS website or by calling your local DPS office. When you arrive, bring your learner permit (if you have one), proof of identity, and proof of residency. The DPS staff will check your documents, then take you to a computer terminal where you will take the test.

You have up to three hours to finish, though most people complete it in 30 to 45 minutes. The test is on a computer, and you move through the questions one at a time. You can review your answers before you submit, and the system tells you when ready whether you passed or failed. If you pass, you move on to the road test scheduling process. If you fail, you can schedule another attempt right away.

Test language options and accessibility

You can take the knowledge test in English or Spanish. If you need the test read aloud or require other accommodations due to a disability, tell the DPS staff when you schedule your appointment. Texas offers accommodations such as extended time, large-print materials, or a reader, though you must request these in advance.

If English is not your first language but you did not request Spanish, you can ask the test administrator for clarification on a word you do not understand. They cannot explain what a question is asking, but they can define a single word if you ask.

What happens if you fail the test

If you do not pass, you receive a score report showing which topics gave you trouble. You can retake the test the same day if you want, or you can study more and come back later. There is no waiting period between attempts in Texas, and you can take the test as many times as you need to pass.

Most people who fail pass on their second or third attempt. The score report is helpful because it tells you which areas to focus on — for example, if you missed several questions about road signs, you know to spend more time on that section of the handbook before your next attempt.

Moving forward after you pass

Once you pass the knowledge test, you are cleared to schedule your road test (also called the driving test). The road test is where a DPS examiner watches you drive and evaluates your actual driving skills. You cannot take the road test until you have passed the knowledge test, and you must have held your learner permit for a certain amount of time depending on your age.

Between passing the knowledge test and taking the road test, keep studying the handbook and practicing your driving. The road test covers many of the same safety concepts as the knowledge test, but now you have to show you can actually do them — parallel park, merge safely, follow traffic signals, and handle different road conditions.

Frequently Asked Questions

Can I use my phone or notes during the test?

No. You cannot bring study materials, phones, or any outside materials into the testing area. The test is proctored, meaning a DPS staff member watches to make sure you are not cheating. You can only use the computer terminal provided.

What if I do not pass all 30 questions — do I still get partial credit?

You need 21 out of 30 correct to pass. If you get 20 or fewer correct, you fail the entire test and must retake it. There is no partial credit — it is pass or fail based on that 21-question threshold.

How long is the knowledge test score good for?

Your passing score is good for one year from the date you pass. If you do not take and pass your road test within that year, you will need to retake the knowledge test before you can schedule the road test.

Is the test the same every time I take it?

No. The test is randomly generated from a question bank, so each attempt will have different questions. This is why studying the handbook is important — you need to understand the concepts, not memorize specific questions.

What if I need to take the test in a language other than English or Spanish?

Texas only offers the knowledge test in English and Spanish. If you need the test in another language, contact your local DPS office to discuss your options, though accommodations are limited.
