Study Your State's Commercial Drivers License Manual

Studying your state's CDL manual is a great way to prepare for the exam. All test questions are taken directly from topics covered in the manual. Despite popular belief, test questions are not formatted or designed to trick you. Visit your local Department of Motor Vehicle (DMV) office to obtain a CDL manual. Or, save time by downloading your free copy here.

How CDL Practice Tests Can Help

There is no question that one of the best ways that you can prepare for the CDL exams is by choosing a website that specializes in delivering accurate and up-to-date practice tests. While the CDL manual offers all of the information you need to pass the tests, many people have a difficult time learning by reading a 100+ page manual. CDL practice tests help you get an idea of what to expect on the real test, as well as test your knowledge so far. They can also greatly enhance your ability to learn the material that you need to know and increase your chances of passing the CDL exams. Take as many as needed. After passing several in a row, you'll know you're ready.

CDL Test Tips

  1. Read each question carefully. The CDL tests usually aren't timed, so relax and take your time.
  2. Answer the easy questions first.. Then go back and spend time on the harder questions. You may not be able to do this with computer-based testing. Some computer-based testing allows you to skip a question, but the skipped question will likely be inserted later in the test.
  3. If your not sure of an answer, narrow down your choices by eliminating answer choices that you know are incorrect.
  4. Look out for answer options that have the words "all," "every," "always," or "never" in them. These choices are often incorrect. It's difficult for something to always or never be true!
  5. Don't change your answer unless you are absolutely sure. Your first instinct is usually best.
  6. Double-check to make sure you're marking the right question with the right answer.
  7. Don't leave any questions blank - they'll be marked wrong on the knowledge tests for the CDL. If you can't figure out an answer to a question, take a guess.
