Passing the official general knowledge exam is the first step toward becoming a licensed commercial driver in Oklahoma. This exam has 50 multiple-choice questions based on the official Oklahoma Commercial Driver’s License Manual (Oklahoma CDL Handbook 2025). You must score at least 80% to pass. To improve your chances of succeeding on your first attempt, you should dedicate the upcoming weeks to studying commercial driving theory.

Most students prefer training with practice tests over traditional learning methods. These tools enable active learning, making it easier to retain information and improve knowledge. Our Oklahoma CDL Class B Practice Test has been designed to significantly boost your learning potential. It consists of 50 multiple-choice questions on pre-trip inspections, safe driving practices, emergencies, and cargo management. Unlike the official general knowledge exam, this practice test is not timed. Please finish each training session at your own pace and avoid rushing.

Great study guides.
Studied for a couple of hours the first night. The next morning studied again and then went to the dmv the same day and passed both test. Missing one question on school bus and two on passenger vehicle. Got my permit and fixing to start class so that I can two more endorsements to my cdl.

Hazmat Endorsement.
I used Driving Tests to get my HME (hazmat endorsement) on my CDL because I needed the ELDT with the newer recent laws implemented. I had accidentally purchased the base plan instead of the HME plan (about difference). It only took a quick email to be refunded the difference and switched to the HME course. It's simple to use and very helpful. You can continuously repeat the tests until the information is as familiar to you as the back of your hand! I'd recommend this service if you need to complete the ELDT for any endorsements, or if you're anxious about passing the DMV tests the first time. Once you reach 80% passing chance they will upload your certificate of completion for ELDT to the TPR (training provider registry) and from there the DMV can verify you completed whatever ELDT you need.
