Indiana CDL permit test: what to expect
The written exam most people call the Indiana CDL permit test is the general knowledge test, and passing it is what gets you a commercial learner's permit rather than the license itself. You need 80% to pass, a federal standard that is the same in every state. The number of questions is set by Indiana, and our practice tests use the common 50-question format.
Once you hold the permit you have to keep it for at least 14 days before you are allowed to attempt the skills test, so it is worth sitting the written exam as early as you can. Practice below until you are clearing Indiana's standard comfortably rather than scraping it.

5 Indiana CDL Practice Questions and Answers
Here are 5 sample Indiana general knowledge questions with the right answer and a quick explanation for each. Read through them, then take the quiz above to see how you do without looking.
1. Why is it advised to avoid driving right next to other vehicles in multi-lane traffic whenever possible?
- A. It blocks the wind, causing your engine to overheat.
- B. They may suddenly swerve into your lane to avoid a hazard in their own lane. (correct answer)
- C. It is illegal to drive alongside a passenger car for more than one mile.
- D. It causes their tires to lose traction.
Why: Driving alongside other vehicles reduces your escape routes. If the other driver swerves to avoid a hazard or changes lanes without seeing you, an accident can occur. It is best to stagger your position.
2. When entering a highway from an on-ramp, you must:
- A. Stop completely at the end of the ramp before merging.
- B. Rely on highway traffic to yield to you.
- C. Accelerate to match the speed of traffic and find a safe gap. (correct answer)
- D. Merge directly into the center lane.
Why: When entering a highway, use the acceleration lane to bring your vehicle up to the speed of traffic and identify a large enough gap to merge safely. Do not stop on the ramp unless absolutely necessary.
3. Why should you turn off your radio and roll down your window when backing?
- A. To conserve battery power.
- B. To hear warnings from your helper or other people. (correct answer)
- C. To comply with federal emissions laws.
- D. To help cool the cab without using AC.
Why: Rolling down the window and turning off the radio eliminates distractions and allows you to hear spoken commands or warning shouts from your helper or pedestrians.
4. During your pre-trip inspection, what should you verify regarding the cargo securement?
- A. That all tie-downs are loosely fastened to allow for load shifting.
- B. That the cargo is pushed entirely against the right side of the trailer.
- C. That the cargo is properly blocked, braced, tied down, and that there are an adequate number of securement devices. (correct answer)
- D. Cargo securement is only the responsibility of the warehouse staff, not the driver.
Why: The driver is ultimately responsible for ensuring the load is adequately secured, blocked, and braced using a sufficient number of undamaged tie-downs before driving.
5. What is true about the braking effect of engine retarders?
- A. They apply braking force to all wheels evenly.
- B. They apply braking force only to the drive wheels. (correct answer)
- C. They apply braking force primarily to the steering axles.
- D. They only apply braking force to the trailer axles.
Why: Retarders (engine, exhaust, hydraulic, or electric) only apply their braking force to the tractor's drive wheels.
