About the Indiana General Knowledge Test
Topics Covered
- ✓Vehicle inspection — Indiana examiners are strict about pre-trip because you'll be driving through construction zones where equipment failures cause massive delays on I-65.
- ✓Basic control and backing — farm supply routes and tight loading docks at grain elevators in central Indiana demand precision backing skills.
- ✓Air brakes — lake effect snow and ice on I-80/94 make proper brake adjustment and anti-lock system knowledge critical for northwest Indiana winter runs.

📘 Study Tips & State Info
Start with the Indiana CDL manual — it's free online from the BMV. Don't just read it cover to cover. Focus on the sections the examiners emphasize: pre-trip inspection steps (they love the order of checking lights, tires, and brakes), air brake components and failure modes, and the proper way to handle downgrades. Indiana has a lot of two-lane highways with no shoulder, so questions about emergency parking and breakdown procedures show up more than you'd expect.
Practice with our test in a quiet environment. Set a timer for 60 minutes. When you miss a question, go back to the manual and read the exact page. That's how you lock it in. Also, pay attention to Indiana-specific numbers: the legal blood alcohol limit for CDL holders is 0.04%, and you can't refuse a chemical test. The BMV asks about these every time.
One last thing: know your vehicle inspection routine cold. Indiana examiners watch you perform it during the skills test, but the written test asks procedural questions like 'What do you check before starting the engine?' and 'What does a low air pressure warning mean?' Get those right and you're halfway there.
Indiana BMV handles all CDL testing. You'll need to schedule an appointment at a CDL testing location — not every BMV branch offers it. The main testing sites include Indianapolis (on N. Keystone Ave.), Fort Wayne, Evansville, South Bend, and Gary. Appointments fill up fast, especially in spring and summer, so book at least two weeks out. Bring your valid driver's license, Social Security card, proof of Indiana residency, and a valid Medical Examiner's Certificate (DOT physical).
The General Knowledge test fee is $35 for the CLP, plus $9 for the written test itself. If you fail, you can retake it the same day at some locations, but you'll pay the $9 again. You have three attempts within one year before the BMV requires you to wait 30 days. Cash, credit, and debit accepted — but some smaller offices are cash-only, so check ahead.
Indiana also requires you to pass a vision screening before the written test. If you wear glasses or contacts, bring them. The minimum is 20/40 with correction. No exceptions. Once you pass the General Knowledge and any endorsements, you'll get your CLP, which is valid for 180 days. You can renew it once without retaking the written test.
About the Indiana General Knowledge Test
Indiana's not flat in the way people think. Sure, it's not Colorado, but you've got lake effect snow dumping on I-80/94 in Gary, construction zones on I-65 that change every season, and rural two-lanes where you're sharing the road with combines and grain trucks. The Indiana CDL General Knowledge test covers the fundamentals every commercial driver needs — vehicle inspection, basic control, shifting, backing, and road regulations — but it's built around the conditions you'll actually face here.
The test is 50 multiple-choice questions. You need 40 correct — 80%. The Indiana Bureau of Motor Vehicles (BMV) administers it when you apply for your Commercial Learner's Permit (CLP). You'll take it on a computer at one of the state's CDL testing locations. No time limit per question, but you've got 60 minutes total. Most people finish in 45.
Here's the thing about Indiana: the examiners want to know you can handle real-world scenarios. They'll ask about proper following distance on slick roads, how to secure a load of steel coils heading through Indianapolis traffic, and what to do when a construction flagger tells you to stop on I-70. The manual's your guide, but you need to think about how each rule applies to a state that's both a major logistics hub and a farming powerhouse.
We built this practice test to match Indiana's version. Same question format, same emphasis areas, same pass score. Take it a few times until you're consistently hitting 85% or better — that way you'll walk into the BMV confident.
