TX CDL General Knowledge Exam Simulator 2025
To become a commercial driver in Texas, you must be at least 18 to drive within the state and at least 21 to drive across state lines. You must provide your Social Security number and show proof of U.S. citizenship when you submit your application. Additionally, you must hold a valid Texas driver’s license, pay the license fee, and pass a physical examination. Commercial driving involves great responsibility, and that’s why the Department of Public Safety (DMV) is so strict with the licensing process.
All applicants are required to pass a 50-question CDL General Knowledge exam before they can obtain a Commercial Learner’s Permit (CLP). You will also need to pass additional written knowledge tests and perhaps skills tests to obtain endorsements for specific types of cargo or vehicles, such as hazardous materials, tank vehicles, or passenger vehicles.
The official Texas commercial motor vehicle driver’s handbook (Texas CDL Handbook 2025) discusses the various aspects of commercial driving. Please read its contents at least once to familiarize yourself with this subject. This knowledge shapes your future career, so you should take as long as you need to master it. To boost your learning potential, you can use the most efficient tools online. Give our other CDL permit practice tests a try, as they enable active learning and make studying easier. When you’re ready, use this Texas CDL General Knowledge Exam Simulator to see how well you’d perform before heading to the DMV office to take the official exam.
We have designed this tool to closely reflect the official testing experience. There are no hints, no feedback, and no assistance of any kind. Once you begin a session, you’re on your own. For your convenience, we have omitted any timer from this simulator. There’s no countdown to pressure you, so please avoid rushing. Read every question twice and only select an answer when you’re confident in your choice. If you start today and integrate our tools into your study routine, you’ll be ready to ace the official exam within a few weeks.
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Triple-checked for accuracy

Content Creation and Verification Process
- Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information. - Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation. - Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy. - Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors. - User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly. - Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.
