Indiana CDL Endorsements and Restrictions

Indiana uses H for hazardous materials, N for tank vehicles, P for passenger vehicles, S for school buses, T for doubles or triples, and X for combined tank and hazardous-material authority. An endorsement adds specialized authority but does not replace the required Class A, B, or C credential.

A CLP authorizes supervised practice only. Passenger and school-bus learners may carry only the persons allowed by the learner rules, and tank training is conducted without prohibited cargo. Hazardous-material endorsement authority is not placed on a CLP.

Indiana may record E for no manual-transmission CMV, L for no air-brake CMV, Z for no full-air-brake CMV, O for no tractor-trailer, M or N for passenger-vehicle group limits, and P or X for learner-stage passenger or tank limits. The vehicle used for testing determines which equipment and group skills were demonstrated.

Indiana restriction T means the driver may not transport hazardous material. It is different from endorsement T, which authorizes doubles or triples after the required knowledge test. The same letter must be interpreted from its credential field and context.

K means intrastate only, V identifies a medical variance, Q limits a holder to an intrastate medical waiver, and R identifies a restricted agricultural CDL used with seasonal validation. Every endorsement and restriction must be read together before a trip.

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.
