Texas CDL Practice Test

The Texas CDL written exam is administered by the Texas Department of Public Safety (DPS). Before you can earn your Commercial Driver's License in Texas, you must pass the General Knowledge test plus any endorsement tests for the type of driving you plan to do.

The General Knowledge test in Texas contains 50 questions, and you need to score at least 80% to pass. All questions are drawn from the Texas Commercial Driver License Handbook, which is the definitive source for your exam.

To get your Texas CDL, follow these steps:

1. Pass the DOT physical exam and obtain your Medical Examiner's Certificate.
2. Study the Texas Commercial Driver License Handbook thoroughly.
3. Pass the General Knowledge written test at the Texas Department of Public Safety (DPS).
4. Pass any required endorsement tests (Air Brakes, Combination, Tanker, Hazmat, Passenger).
5. Obtain your Commercial Learner's Permit (CLP).
6. Complete behind-the-wheel training and practice.
7. Pass the road skills test (pre-trip inspection, basic control, and on-road driving).

The best way to prepare is to combine focused study of the official manual with realistic practice tests. Our free practice tests are built from the same question styles and topics, and every answer includes a plain-English explanation so you learn the material as you practice.
