Are you looking for a tool that can help you pass your theory exams? Our practice tests have been designed to significantly boost your learning potential and make you a better commercial driver. You can access them on any compatible device that is connected to the internet. The practice test that you’re about to take is the fourth in our Oklahoma CDL Combination Vehicles Practice Tests series. Consisting of multiple-choice questions, this intuitive tool accurately reflects the latest updates brought by DPS rules or state law. We frequently update it (most recently for January 2026), so you will always practice with the latest version.
The Commercial Driver’s License Manual (Oklahoma CDL Handbook 2026) is an official resource published by the DPS. Section 6 teaches you everything you need to know to safely operate combination vehicles. You will learn how to prevent skids and jackknives, coupling and uncoupling procedures, and pre-trip inspections specific to combination vehicles. We recommend reading this section multiple times during your learning phase.

It is perfectly normal to make mistakes, especially during your first few attempts. Your personal Challenge Bank™ automatically stores questions you get wrong so that you can practice with them later. Please visit this section at the end of your study sessions to review your mistakes and learn from them. The bookmark icon allows premium users to add any question to their Challenge Bank.
Many of our practice tests are untimed, including this one. Rushing will only cause you to make more mistakes, so you should finish each practice session at your own pace. This practice test is available in multiple languages. You can select yours from the test settings menu located in the top-right corner of the page.
A Class A CDL opens up plenty of career opportunities. If you plan to drive combination vehicles, you must understand the responsibilities that come with this job. Use this practice test for several weeks and after you’ve aced it, you can continue your training with our Free Oklahoma CDL Permit Practice Test.
