Indiana Trucking Regulations

Indiana occupies a central position in Midwest freight, with I-65, I-70, I-74, I-80/90 (Indiana Toll Road), and I-94 forming a dense Interstate network. Indianapolis serves as a major logistics hub — its position near the geographic center of the eastern U.S. makes it a preferred distribution and cross-dock location for national carriers. Northwest Indiana, anchored by the Port of Indiana-Burns Harbor and heavy steel and manufacturing industries, generates some of the highest truck volumes in the state. The Indiana Department of Revenue (IDOR), Motor Carrier Services division, administers IFTA and IRP. INDOT handles oversize/overweight permits and highway standards. The Indiana State Police Motor Carrier Inspection Division enforces weight and safety regulations, with active fixed weigh stations on major corridors. The Indiana Toll Road (I-80/90), operated by a private concessionaire, requires E-ZPass and has its own enforcement structure. Carriers should note that Indiana has no state-specific axle weight formula exceptions beyond the federal bridge formula — standard federal limits apply on all Interstates, and overweight permits must be obtained for any excess.
