Free ASVAB Auto Information Practice Test
Practice the ASVAB (Armed Services Vocational Aptitude Battery) Auto Information section with 10 free questions, each with a clear explanation and a Scout tip. No sign-up needed. Auto Information doesn't count toward your AFQT, but it's used in line scores that decide which military jobs you qualify for.
What Auto Information Covers
Auto Information (AI) tests how cars work:
- The engine: the four-stroke cycle, fuel, and ignition.
- Drivetrain and transmission.
- Brakes, steering, and suspension.
- Cooling, charging, and electrical systems.
On the computer version it's a separate subtest; on the paper version it's combined with Shop Information.
