About this test

10 min to complete
Available in EN and ES

Updated for July 2024, this Texas General Knowledge practice test contains another 142 questions based on the official CDL (Commercial Driver’s License) manual. You can use this test to prepare for the General Knowledge portion of the TX CDL exam. These questions are multiple-choice, with three possible answers for each question. Only one of those answers is correct. If you’re not sure about the correct answer, you can use the hint provided for each question. Each hint points you to the correct answer without giving away the correct answer itself. This should allow you to make an informed decision about the correct answer, even if you don’t actually know it. There is no time limit for completing this practice test. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers.

Enhance your preparation with our comprehensive General Knowledge test collection, tailored to cover all key topics of the CDL exam. For a complete understanding of the expenses involved, check out our guide on CDL license cost, and for a step-by-step guide to getting your CDL, visit our CDL license guide.
