District of Columbia CDL General Knowledge Test 10 2025

Updated for January 2025, this District of Columbia General Knowledge practice test contains another 50 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 DC 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.
