To 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.
