The Texas written test covers road signs, traffic laws, and safe driving practices
The Texas written test, officially called the Knowledge Test, is a multiple-choice exam you take at your local Texas Department of Public Safety (DPS) office. You answer questions about what road signs mean, when you must yield, speed limits, parking rules, and how to handle emergencies on the road. The test has 30 questions, and you need to answer at least 21 correctly to pass — that's a 70 percent score.
The test is given on a computer at the DPS office. You sit at a terminal, read each question, and select your answer from four choices. The whole thing usually takes 20 to 30 minutes. If you pass, you move on to the driving test. If you don't pass, you can retake it the same day or come back another day, depending on the office's policy.

What topics appear on the test
The test draws from the Texas Driver Handbook, a free booklet published by DPS. About half the questions ask you to identify road signs — what a red octagon means, what a yellow diamond warns you about, what a green arrow tells you to do. The other half cover driving rules: when you must yield to another vehicle, what to do at a four-way stop, how fast you can drive in a school zone, what lane you should use on a highway, and how to handle skids or brake failure.
You'll also see questions about alcohol and driving, distracted driving, sharing the road with trucks and motorcycles, and what to do if a police officer pulls you over. A few questions test whether you know the rules for new drivers — Texas has different restrictions for 16-year-olds than for adults, so if you're under 18, expect questions about those limits.
How to study for the test
The Texas Driver Handbook is the official source for everything on the test. You can read it as a PDF from the Texas DPS website, or pick up a printed copy at any DPS office for free. Read through it once, then go back and focus on the sections that feel least familiar — most people know what a stop sign means, but fewer know the exact rules for a four-way stop or how to merge safely on a highway.
Many people study by taking practice tests online. Several websites offer free Texas practice exams that mimic the real test format — 30 questions, multiple choice, same topics. Taking a practice test twice tells you whether you're ready: if you score above 24 or 25 on a practice test, you'll likely pass the real one. If you're scoring below 21, go back to the handbook and review the sections where you missed questions.
Study for a few days rather than cramming the night before. Your brain retains information better when you spread learning across multiple sessions. Spend 20 or 30 minutes a day for a week, rather than three hours the day before your test.
What to bring to the DPS office
Bring your current ID or passport, proof of your Social Security number (a Social Security card, W-2, or tax return), and proof of your Texas residency (a utility bill, lease, or bank statement with your name and address). If you're under 18, bring a parent or guardian and their ID as well. Bring the documents in their original form — photocopies usually don't count.
Arrive early. DPS offices can have long waits, especially on weekends and after school hours. Many offices let you check in online before you arrive, which can cut your wait time. Check your local DPS office's website to see if that option is available.
What happens during the test
A DPS employee will check your documents, take your photo, and walk you to a computer terminal. They'll explain how to use the system — usually you use a mouse to click on your answer, then click "Next" to move to the question. You can't go back to previous questions, so read each one carefully before you answer.
The test is in English. If you need the test in Spanish, tell the DPS employee before you sit down — Texas offers the Knowledge Test in Spanish as well. You can't use a phone, notes, or any other materials during the test. The office is usually quiet, but there may be other people testing at nearby terminals.
When you finish, the computer shows your score when ready. If you passed, the employee will tell you what to do next — usually scheduling your driving test. If you didn't pass, ask which topics gave you trouble so you know what to study before you retake it.
If you don't pass on your first try
Failing the test is common, and it doesn't affect your ability to retake it. Most DPS offices let you retake the test the same day, though a few have policies limiting you to one attempt per visit. Call your local DPS office ahead of time to ask about their retake policy.
Between attempts, spend 30 minutes to an hour reviewing the handbook sections that tripped you up. Don't just retake a practice test — actually read the material. Many people miss the same questions twice because they memorized the wrong answer the first time. Understanding why an answer is correct matters more than memorizing it.
Frequently Asked Questions
Can I take the test in Spanish?
Yes. Texas offers the Knowledge Test in Spanish at all DPS offices. Tell the employee when you check in that you want to test in Spanish, and they'll set you up at a terminal with the Spanish version. You answer the same 30 questions and need the same score to pass.
What if I fail the test twice?
You can retake it as many times as you need. There's no limit on the number of attempts, though each attempt may have a fee. After a second or third failure, consider spending more time with the handbook or taking multiple practice tests before you go back to the office.
How long is the test score good for?
Your passing score is good for 12 months from the date you pass. During that year, you can schedule and take your driving test. If you don't take the driving test within 12 months, you'll need to retake the Knowledge Test before you can schedule a driving appointment.
Do I need to memorize exact speed limits?
No. The test asks about speed limit rules — like "what's the speed limit in a school zone" — not specific numbers for specific roads. The handbook tells you the rules, and the test questions follow that same format. You won't be asked "what's the speed limit on Farm Road 423?"
What if I'm nervous during the test?
Take a breath before you start. You've studied the material, and the questions are straightforward. If a question confuses you, skip it mentally and come back to it — wait, you can't go back. Read each question twice before you click your answer. If you're really anxious, arrive 15 minutes early and sit in the waiting area to calm down before the test begins.
