In Indiana, drivers of combination vehicles, such as semi-trucks and tractor-trailers, can benefit economically from several sectors of the state’s economy. Indiana is the eighth largest agricultural exporter in the country. Major products include corn, meat animals, poultry and eggs, and dairy. Truckers transport these products to distribution hubs or directly to grocery store chains. Nearly 17% of the state’s non-farm workforce is employed in manufacturing, notably motor vehicles, auto parts, and pharmaceuticals. These industries require truckers to deliver supplies and equipment to them as well as transport their products. Finally, several cities, such as Indianapolis, are important logistics hubs, creating economic opportunities for truckers to move goods.
As befits its role as a major logistics hub, Indiana has numerous major trucking routes connecting it to markets in the Midwest and beyond: the transcontinental routes Interstates 80 and 90 and U.S. Route 30, the east-west route Interstate 70, the major north-south route Interstate 65, and the Midwest routes Interstates 69 and 74.

There are three classes of Commercial Driver’s Licenses (CDLs): Class A, Class B, and Class C. To drive heavy combination vehicles such as semi-trucks and tractor-trailers, you’ll want to obtain a Class A CDL. This class of CDL allows you to operate large combination vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more, in which the towed vehicle weighs more than 10,000 pounds.
To obtain any class of CDL, you must pass a medical examination, a General Knowledge test on the general theory of commercial driving, and a skills test showing that you can operate commercial motor vehicles safely. But wait; there’s more!
To be allowed to operate combination vehicles, you must also pass a Combination Vehicles knowledge test on the theory of operating combination vehicles. Passing all these tests will take a lot of study and practice. These official knowledge tests are based on the official Indiana Commercial Driver’s License Manual (Indiana CDL Handbook 2026). But it’s not that easy to pass these tests just by reading this study guide a few times.
You’re probably here because you could use some more help to pass the Combination Vehicles knowledge test. Great! We can do that.
This free Indiana CDL Combination practice test is also based on the official manual, and it’s up to date as of January, 2026. To make your learning process easier, each of the 25 questions comes with a helpful hint and an explanation of the correct answer. The practice questions and answers on this test will assess your knowledge of such topics as combination braking systems, combination driving techniques, coupling and uncoupling, and pre-trip inspections.
