Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements

Be sure not to make the mistake of going to the DMV to acquire your Oklahoma Air Brakes endorsement without practicing first. Practicing will give you the confidence and knowledge you need to move through the test with ease. Then, you will be certain to receive your endorsement and further your career. Your endorsement will open up opportunities that have been closed previously. Keep in mind it all begins with your endorsement, and a practice test makes it much easier to get that endorsement.

Things to Expect with the Practice Test

Because the Oklahoma Air Brakes practice test is designed from the official Oklahoma CDL manual, the questions closely resemble the questions you will see on the authorized CDL test. The wording might be slightly different, but the meaning remains the same. The practice test has 25 questions. Once you master these questions, you will be ready to move onto the official CDL test at the DMV.

As you take the test, it is a good idea to make a note of the questions that you have problems with so you can study them after you finish the practice test. That way, you will be able to improve before you have to take the official test. Then, go back and retake the test to see if you get those answers correct. Keep doing this until you are ready to take the actual thing.

Getting Ready on Test Day

When test day finally comes, you might have some jitters. That is ok, but don’t let your nerves get the best of you. The best thing to do is to take your Air Brakes practice test one more time. Then, you will remember that you have the knowledge necessary to pass with flying colors Sometimes, a boost of confidence is all that you need to bring home your OK Air Brakes endorsement.

Good luck on your practice test, and keep in mind, you can take it as many times as you wish. Don’t rush the process. The practice test is here to help you as you move closer to obtaining your endorsement. Use it as a tool to help you achieve your goals.
