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

Practice makes perfect when it comes to taking the Oklahoma CDL Combination Vehicles test. Don’t walk in blind and take the real test without going over the practice questions first. When you take your test at the DMV, your answers will be recorded and part of your permanent record. Give yourself the opportunity to succeed by taking the practice test first. That way, you will have the information you need to breeze through the real test with ease. Then, you will get your CDL Combination Vehicles endorsement without any issues.

Taking Your Practice Test

The practice test is developed to closely resemble the official CDL Combination Vehicles test. Each question is taken from the official Oklahoma CDL manual and closely resembles the questions on the actual test. This gives you the experience necessary to master the questions before you take the actual test. You can’t get this type of information by simply reviewing for the test.

Because the practice test closely resembles the actual test, it is essential that you pay close attention to each of the 20 questions. You might have some trouble from time to time, and that is OK. That is the point of a practice test. Simply note down the number of the troublesome question and then study that subject some more. Then, retake the test. The great thing about a practice test is you can take it as often as you would like before you go to the DMV to take the real thing.

Taking the Official Test

When you’re finally ready to take the official test, you will need to go to the DMV. Remember everything you learned from your OK Combination Vehicles practice test, and don’t be afraid to take the test one more time if necessary. Then, go into the DMV with confidence, knowing that you’re going to do well on the test.

Best of luck with your practice test! Remember that as long as you use the practice test as a guide, you have the information necessary to earn your endorsement. You are well on your way to reaching your goals!
