Intermodal Carrier Insurance
Intermodal carriers operate inside a paperwork-heavy network of terminals, equipment providers, brokers, and warehouse customers. The insurance conversation often starts with who has custody of the container or chassis.
Plain-English summary
Intermodal businesses should discuss auto liability, cargo, trailer interchange or non-owned trailer, general liability, terminal certificates, and equipment agreements.
Operational distinction
This is a business model page. The vehicle may be a day cab, sleeper, or small fleet, but the defining feature is container/chassis movement around intermodal facilities.
Documents to collect
- Terminal access requirements
- Equipment interchange agreements
- Chassis provider instructions
- Broker or steamship line certificate wording
Why certificates take extra review
A terminal or equipment provider may ask for wording that is not the same as a normal broker COI. The carrier should send the exact requirement to the agent before assuming the policy can support it.

Questions carriers ask
Is intermodal carrier insurance just truck liability?
No. Equipment custody, terminals, cargo, and certificates often need separate review.
Does trailer interchange coverage apply automatically to every container movement?
Not automatically. Trailer interchange depends on whether a written interchange agreement exists and whether the chassis or container qualifies under the policy terms.
