View All PlansTo legally operate combination vehicles (such as semi-trucks and tractor-trailers), you must obtain a Class A CDL (Commercial Driver’s License). In Indiana, the Bureau of Motor Vehicles (BMV) employs a strict licensing process that every aspiring commercial driver must complete. Your first step is to obtain a CLP (Commercial Learner’s Permit) by submitting an application, paying the licensing fees, passing a medical examination and a vision test, and scoring 80% or higher on several theory exams.
The official general knowledge test will evaluate your understanding of general commercial driving theory. This subject is discussed in the official Commercial Driver License Manual (Indiana CDL Handbook 2025), which you should read multiple times during your learning phase. Because driving 18-wheelers requires extensive knowledge, you must also pass the official combination vehicles knowledge test. Your knowledge of coupling and uncoupling procedures, air brake systems in combination vehicles, and jackknife prevention will be evaluated through 20 multiple-choice questions.
To help you achieve a passing score on your first attempt, we offer a series of Indiana CDL Combination Vehicles Practice Tests. The practice test that you’re about to take includes questions similar to those you will encounter on the official combination vehicles knowledge exam. It is not timed, so you can study at your own pace. The latest updates brought by BMV rules or state law are accurately reflected in this practice test, which we regularly update (most recently for December 2025).
Our practice tests add flexibility to your learning process. They are available online 24/7, and you can access them on any compatible device. You can run a quick training session while waiting in line at the grocery store, on your daily commute, or even while traveling. Keep in mind that you will need a stable internet connection to access our practice tests.
The most determined students succeed by adopting a systematic approach. You can do the same by training with efficient tools. Our Free Indiana CDL Permit Practice Test can be a game-changer for those struggling to understand general commercial driving theory. Check it out and use it alongside the official commercial driver license manual to boost your learning potential.
