This commercial driver study guide covers relevant Federal Motor Carrier Safety Administration (FMCSA) Entry-Level Driver Training (ELDT) concepts and Indiana commercial driver knowledge topics. Review the regulations, procedures, and safety checklists below as part of your CDL and commercial learner permit (CLP) preparation.
Class A, B, and C
Indiana applies the federal vehicle groups. Class A covers a combination at 26,001 pounds or more when the towed unit exceeds 10,000 pounds. Class B covers a single vehicle at 26,001 pounds or more and such a vehicle towing no more than 10,000 pounds. Class C applies below those thresholds when the vehicle is designed for 16 or more people including the driver or transports placarded hazardous material or a listed select agent or toxin.
Age and operating range
An Indiana applicant may obtain intrastate commercial authority at age 18. Interstate commercial operation and operation as a school-bus driver require age 21. Hazardous-material authority is also subject to the federal age and security requirements.
Base credential and record
The applicant must hold a valid, unexpired Indiana driver license and cannot have a suspended, revoked, canceled, disqualified, or otherwise invalid driving privilege. Indiana requires disclosure of every licensing state during the preceding ten years so the commercial record can be checked.
Application sequence
Complete self-certification and required medical qualification, pass the knowledge modules, obtain the CLP, complete applicable ELDT and Indiana's first-time applicant human-trafficking video, hold the CLP for 14 days, pass the three-part skills test, and finish issuance at a BMV branch before the permit expires.
Current non-domiciled pause
Indiana's live BMV transfer page states that, beginning September 29, 2025, the state ceased all non-domiciled CLP and CDL transactions, including new, amended, duplicate, transfer, renewal, and upgrade applications. This live policy controls over older eligibility language in the six-page state supplement.
Exam focus
Apply the rule to the exact Indiana vehicle, credential, date, trip, test stage, and operating facts. A later live BMV or DOR instruction controls a transaction when it directly supersedes older procedural text; the official manual remains the primary safety and test-content source.
Commercial Driver License Exam Readiness: Achieving a passing grade of 80% or higher on state DMV commercial driver knowledge exams requires mastery of federal vehicle inspection procedures, gross vehicle weight ratings (GVWR / GCWR), braking mechanics, and road safety regulations.
