What the Texas knowledge test covers and how it works
Texas administers the knowledge test through the Department of Public Safety (DPS). The test has 30 multiple-choice questions drawn from the Texas Driver Handbook, and you must answer at least 21 correctly to pass. The test is offered in English and Spanish, and you take it at a DPS office or an approved third-party testing location.
The questions cover three main areas: traffic laws and regulations, road signs and their meanings, and safe driving practices. Texas does not publish the exact questions in advance, but the Driver Handbook contains all the material the test draws from. You can read the handbook free online at the DPS website or request a printed copy at any DPS office.
The test itself takes about 10 to 15 minutes. You sit at a computer terminal or paper form (depending on the location) and answer each question before moving to the next. Once you submit your answers, you receive your score when ready. If you pass, you move forward in the licensing process. If you fail, you can retake the test, but DPS requires you to wait at least one day before your next attempt.
Key Takeaways

- Bring a valid form of ID and proof of residency to the testing location; requirements vary slightly by age and citizenship status.
What documents you need to bring to the test
Before you sit for the knowledge test, DPS requires proof of identity and residency. A valid passport, military ID, or state ID card satisfies the identity requirement. For residency, bring a utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days that shows your current Texas address.
If you are under 18, you also need a completed DPS form VTR-289 (Parental Consent for Minors), signed by a parent or guardian. If you are explore for a Real ID-compliant license, bring your Social Security card or a document showing your Social Security number, plus a birth certificate or passport. Non-citizens explore for a standard (non-Real ID) license need proof of lawful presence in the United States, such as a visa or employment authorization document.
Bring originals or certified copies — photocopies alone are not accepted. If any of your documents are in a language other than English, bring a certified English translation as well. DPS offices can tell you over the phone whether your specific documents will work, so calling ahead can save a trip.
How the test questions are structured
Each question on the Texas knowledge test presents a scenario or asks about a rule, with four possible answers. The questions test whether you understand the rule itself, not just whether you memorized a fact. For example, rather than asking "What is the speed limit on a residential street?" a question might show a sign or describe a situation and ask what you should do.
Road sign questions make up a significant portion of the test. You will see images of actual Texas road signs and be asked to identify what they mean or what action they require. The Driver Handbook includes a full section on signs, organized by type: warning signs (yellow), regulatory signs (white and red), and information signs (green and blue).
Safe driving questions cover right-of-way rules, following distance, turning and lane changes, parking, and how to handle emergencies like brake failure or a skid. Texas law questions cover seat belt use, child passenger safety, distracted driving, and the consequences of violations. The test does not ask trick questions or test obscure rules — it focuses on the laws and practices that affect most drivers most often.
Where to take the test and how to schedule
You can take the knowledge test at any DPS Driver License office across Texas. DPS maintains a location finder on its website where you can enter your city or zip code and see nearby offices, their hours, and whether they are currently accepting walk-ins or require an appointment. Many offices now use an online appointment system; you can book a time slot up to 30 days in advance.
Third-party testing locations — private businesses licensed by DPS to administer the test — are also available in many areas. These include some driving schools and testing centers. Third-party locations often have more flexible hours and shorter wait times than DPS offices, but they may charge a fee in addition to the DPS test fee. The DPS website lists approved third-party locations by county.
Walk-in testing is still available at most DPS offices, but wait times vary. During peak hours (late morning and early afternoon on weekdays), you may wait 30 minutes to an hour. Early morning or late afternoon visits typically have shorter waits. If you are in a hurry, booking an appointment online is the most reliable way to control your wait time.
The cost and what happens if you fail
The DPS knowledge test fee is $10. If you take the test at a third-party location, you pay the $10 DPS fee plus whatever fee that location charges — typically $5 to $15 more. You pay the fee when you arrive for your test, whether you pass or fail.
If you do not pass on your first attempt, you can retake the test the next calendar day. There is no limit to how many times you can retake it, and you pay the fee each time. Some people pass on the first try; others take two or three attempts. Taking time to study the Driver Handbook between attempts significantly improves your chances on the next try.
A failed test does not affect your ability to get a license later — it is straightforward one step in the process. However, if you fail the test multiple times, DPS may require you to complete a driver education course before you can test again. This requirement varies by your age and the number of failures. DPS staff can tell you whether this applies to you if you fail more than once.
How to study for the test effectively
The Texas Driver Handbook is the only study material you need. It is organized by topic: traffic laws, road signs, safe driving practices, and special situations like driving in bad weather or towing a trailer. Read through the entire handbook at least once, paying close attention to sections that cover rules you are less familiar with.
After reading the handbook, focus on road signs. Print out the sign section or view it on your phone, and quiz yourself on what each sign means. Road signs make up roughly one-third of the test, so knowing them well is essential. The handbook shows each sign with its meaning and the action drivers should take.
Some people find it helpful to take practice tests online. Several websites offer free Texas practice tests with questions similar in format and difficulty to the real test. These are not official DPS materials, but they can help you get used to the question format and identify weak areas. Practice tests are most useful after you have read the handbook once — they help reinforce what you learned rather than replace reading the handbook.
Frequently Asked Questions
Can I take the knowledge test before I turn 16?
Yes. Texas allows you to take the knowledge test at 15 years old if you are enrolled in a driver education course or have completed one. You must pass both the knowledge test and the driving test, and you must hold a learner permit for at least six months before you can receive your license. Check with your local DPS office about the exact age rules for your situation.
What if I fail the test three times?
After three failures, DPS may require you to complete a driver education course before you can test again. This requirement depends on your age and the reason for your failures. Contact your local DPS office to find out whether this applies to you and which courses are approved in your area.
Is the test offered in languages other than English and Spanish?
No. Texas offers the knowledge test in English and Spanish only. If you need the test in another language, you must bring a certified interpreter to the DPS office. The interpreter must be at least 18 years old and cannot be a family member. DPS staff can provide more details about the interpreter process when you call to schedule.
How long is the knowledge test score valid?
Your passing score is valid for 12 months from the date you pass. If you do not complete the rest of the licensing process (the driving test and vision screening) within that year, you will need to retake the knowledge test. If you pass and then take the driving test within a few weeks, this is not a concern.
Can I use my phone or notes during the test?
No. The test is proctored, meaning a DPS employee or approved test administrator watches while you take it. You cannot use your phone, notes, the Driver Handbook, or any other materials during the test. You are allowed to use the restroom if needed, but you cannot leave the testing area with your test in progress.
