- You must be between 16 and 17 years of age to apply for a provisional driver license.
- You must be 18 years old or older to receive a class C driver license.
If you are under 25, you need to enroll in a driver education course and you can take the DMV written test at the driving school. After passing the exam, you have to visit a Texas driver license office to obtain a learner license. Alternatively, you can choose to take the permit test at any driver license office.
You'll need to bring these documents to a driver license office:
- A completed application signed by your parent/legal guardian, either at the driver license office or in front of a public notary.
- Proof of U.S. citizenship or lawful presence.
- Two proofs of your Texas residency.

- Proof of your Social Security number.
- Texas Vehicle Registration and proof of insurance of your vehicle (if available).
- Texas Driver Education Certificate and proof of passing the DMV written test (if applicable).
- Verification of school enrollment, or a high school diploma or equivalent (for minors).
The DMV written test in Texas is available in English or Spanish and you need to understand road signs written in English. If needed, you can bring a translator, but they can only assist you in communicating with the specialist before and after the exam.
To prepare for the DMV written test, read the Texas Driver's Handbook and take our free practice tests to verify your knowledge. Topics covered on the exam include road signs, parallel parking, turning, passing a vehicle, yielding the right of way, etc. Once your scores are good, you are ready for the real test.
The Texas DMV written test consists of 30 multiple-choice questions and is based on the information provided in the manual. Remember, you have 1 hour to complete the exam. Taking numerous practice tests and thoroughly studying the handbook will increase your chances of success.
You must answer at least 21 questions correctly, and you can miss up to 9 questions to pass the test. The minimum score required to succeed in the exam is 70%. Take your time during the test to make sure you understand the questions well.
For new drivers in Texas, specific restrictions apply.
If you have a learner license:
- You must drive only under the supervision of a licensed adult aged 21 or older seated in the front passenger seat.
If you have a provisional driver license:
- You are not permitted to drive with more than one passenger under 21 who is not a family member.
- Driving a motor vehicle between midnight and 5:00 a.m. is prohibited, except for work, school-related activities, or medical emergencies.
Additionally, all drivers under 18 years old are prohibited from using any wireless communication device, except in emergencies. Furthermore, drivers under 21 are prohibited from operating a vehicle after consuming any amount of alcohol (Zero Tolerance law).
Your learner license will remain valid until your 18th birthday. Use this period to fulfill all the necessary requirements before applying for a provisional driver license. If you are under 18 years old, you can renew it in person at a Texas driver license office.
After the first failure, your application will be held for 90 days. After 90 days or after three failed exams, you will have to submit a new application and pay another fee.
