You want to obtain a Commercial Learner’s Permit (CLP), right? And so, you’re studying to pass the official CDL General Knowledge test (a necessary step toward a CLP)? We can help! We’re sure you’ve been told to read the Texas Commercial Motor Vehicle Drivers Handbook (Texas CDL Handbook 2026). And you should. It’s got all the information covered by the official knowledge test. But you may have already gotten a sinking feeling that you may not be able to absorb and memorize it all without additional help. That’s why we’re here.
This free Texas CDL permit practice test is also based on the official handbook and is up to date as of May, 2026. Practicing with it will enable you to think about what you read in the manual, reinforcing it in your mind. The test contains 20 multiple-choice practice questions. To speed up your learning, our automated assistant can provide you with a hint and an explanation of the correct answer for each question. The practice questions on this test will assess your knowledge of such topics as cargo management, commercial driving regulations, emergency preparedness, and pre-trip inspections. Keep practicing your knowledge with as many of our practice tests as you can, as often as you can, until you feel confident that you’ve mastered the material and can ace the official General Knowledge test.
Your CLP will allow you to practice commercial driving under the supervision of a licensed CDL holder. Note that you may have to pass some other official knowledge tests to be able to operate certain types of vehicles. For example, the Combination Vehicles and Air Brakes knowledge tests are a virtual necessity for driving semi-trucks. (Don’t worry; we have practice tests on those subjects, too.)
Then it will be time to start practicing driving (under supervision) for the skills test for your CDL. The skills test consists of three parts: basic vehicle maneuvers (such as backing), a pre-trip inspection of the vehicle, and a road test. You must perform the skills test in a vehicle that’s consistent with the class of CDL you’re applying for and the types of vehicles you’ll be driving in your career.
Once you get your CDL and the endorsements you need for the vehicles you’re interested in driving, you can start driving the roads of Texas to earn money as a commercial driver. You’ll soon become familiar with the major commercial routes: Interstates 10, 35, and 45; U.S. Route 83; and State Highway 130. (SH-130 can provide an alternative route between San Antonio and Austin when I-35 is heavily congested.)
What to review before the CLP knowledge test and CDL endorsement practice
Based on recent Driving-Tests.org answers for this test family.
Review mirror adjustment, blind spots, scanning intervals, and checking traffic before turns, lane changes, and backing.
Review blind spots, turns, pedestrian and cyclist space, railroad crossings, and communication with smaller vehicles.
Review axle weights, load balance, center of gravity, and how weight affects braking, steering, and rollover risk.
Review when to re-check cargo, tie-downs, seals, weight balance, and warning signs of shifting or leaking cargo.
CLP and General Knowledge requirements before skills testing and endorsements
Start with General Knowledge for your TX CLP. Add Combination Vehicles, Air Brakes, or endorsement tests only when they match the license class and endorsements you need.
Passing the written test does not give you a CDL. After your CLP is issued, federal rules require you to hold it for at least 14 days before the CDL skills test.
Pick the right medical self-certification category early. If you drive non-excepted interstate, keep your DOT medical certification current with the state licensing agency.
ELDT may be required before Class A or B skills testing, first-time Passenger or School Bus endorsements, or the HazMat knowledge test. Your training provider submits completion through FMCSA's Training Provider Registry.
Use General Knowledge as the base, then move into the CDL tests that match your license class and endorsements.
