About the Indiana General Knowledge Test
The General Knowledge test is required for every CDL applicant in Indiana, no matter the class or endorsement. It pulls from the Indiana CDL handbook and covers vehicle control, managing speed and space, hazard awareness, and safe-driving fundamentals.

Indiana CDL Requirements & Fees
Indiana follows the federal CDL framework: a minimum age of 18 for intrastate driving and 21 for interstate, a commercial learner's permit you must hold at least 14 days before the skills test, and the 80% passing standard. License fees and retake rules are set by Indiana and change from time to time, so check the official source below for current amounts before you go in.
