Delaware trucking sits inside a four-agency regulatory framework that fleet owners operating across
the I-95 spine and the Delmarva agricultural corridor need to understand before binding the program.
Interstate authority runs through FMCSA at the federal level; state motor carrier registration runs
through the Delaware Department of Transportation; insurance carriers and policy forms are regulated
by the Delaware Department of Insurance; workers compensation is administered by the Delaware
Industrial Accident Board as a competitive-market system (not a state monopoly fund).
Federal authority — FMCSA, USDOT, and PHMSA
Interstate Delaware motor carriers register with the
Federal Motor Carrier Safety Administration
for a USDOT number and motor-carrier authority, file BMC-91 or BMC-91X public-liability proof of
insurance through their carrier, and carry the MCS-90 endorsement on the auto liability policy.
Hazmat operations layer PHMSA placarding, training, and routing requirements on top of FMCSA
authority — and the Wilmington industrial corridor plus the Seaford chemical-industry legacy zone
are the two Delaware clusters where that layer matters most.
Delaware Department of Transportation (DelDOT)
DelDOT
administers motor carrier registration, IRP and IFTA processing, UCR coordination, and oversize and
overweight permits across the state highway and interstate network — I-95, I-295, I-495, US-13,
US-113, US-301, US-1, and the surface arterial network feeding the Port of Wilmington. Heavy-haul
operators running permitted loads work directly with DelDOT on routing approvals; the compact
geography of the state means many heavy-haul moves are effectively multistate operations from the
first mile.
Delaware Department of Insurance (DDOI)
DDOI
regulates the property and casualty carriers that write Delaware trucking auto liability, motor
truck cargo, physical damage, trailer interchange, and pollution liability programs. Carrier
admission, rate filings, policy form approval, and consumer complaint resolution all run through
DDOI. Filings carried by the insurance carrier on behalf of the motor carrier (BMC-91, BMC-91X)
sit at the federal level, but the carrier’s authority to write the policy in Delaware runs through
DDOI.
Delaware Industrial Accident Board (IAB)
The Delaware Industrial Accident Board administers the state workers compensation system as a
competitive market. Delaware is not a state-monopoly workers compensation state — coverage is
placed through private insurance carriers, including specialty motor-carrier markets that
understand interstate trucking payrolls. Owner-operators leased under 1099 arrangements raise
classification questions that affect both workers compensation eligibility and audit exposure, and
the IAB oversees the dispute-resolution process when a classification question reaches a contested
claim.
