Indiana motor carriers operate under a layered federal-and-state regulatory framework
centered on INDOT Motor Carrier Services, the Indiana Department of Insurance, and
the Workers Compensation Board. The pieces matter — and they do not always talk to
each other.
The Indiana Department of Transportation, INDOT, administers the
state highway system, manages oversize and overweight permitting, and operates
INDOT Motor Carrier Services — the agency office that handles intrastate operating
authority, IRP and IFTA registration, and the state oversize-overweight permits.
The
INDOT website
documents the permit portal, the seasonal route restrictions, and the pilot-car
requirements that scale with load size. Intrastate Indiana authority for motor
carriers running freight purely within state lines routes through INDOT Motor
Carrier Services.
The Indiana Department of Insurance, IDOI, regulates the carriers
writing commercial auto, motor truck cargo, physical damage, general liability, and
workers compensation on Indiana-domiciled motor carriers, oversees rate and form
filings, and handles consumer complaints. The
IDOI website
lists licensed and surplus-lines-eligible carriers and the procedural rules for
rate and form filings. Unlike neighboring Ohio, Indiana is a standard private-market
workers compensation state — the workers compensation line is written by private
carriers under IDOI rate-and-form regulation alongside the rest of the motor
carrier policy stack.
The Workers Compensation Board of Indiana, WCB, administers the
Indiana Workers Compensation Act, sets procedural rules for contested claims, and
adjudicates disputes between injured workers and insurance carriers. Workers
compensation rates are filed with the IDOI under NCCI loss-cost guidance for
trucking class codes. The
WCB website
documents the claim procedures, the appeals process, and the medical-fee schedules
that follow. Interstate motor carriers with Indiana-domiciled drivers need a policy
that responds under the Indiana act for those drivers and under the applicable
state act for drivers domiciled elsewhere.
The federal layer — FMCSA financial responsibility under 49 CFR § 387, the BMC-91
and BMC-91X filing forms, hours of service, driver qualification, drug and alcohol
testing, and vehicle maintenance — applies on top of the Indiana state framework.
The
Federal Motor Carrier Safety Administration
publishes the financial responsibility regulations and the BMC filing forms that
every interstate Indiana motor carrier holds. The federal-state interaction is
generally clean in Indiana, with INDOT Motor Carrier Services handling the
intrastate piece and FMCSA handling the interstate piece on parallel tracks.
