The BOC-3: Trucking’s Legal-Service Filing

Quick Answer

Form BOC-3 designates process agents — people or companies who can accept legal papers (service of process) on your behalf — in each state where you operate. Every motor carrier, broker, and freight forwarder must have one on file before FMCSA grants operating authority (49 CFR 366.109T). Carriers cannot self-file: only a process agent files the BOC-3 for a carrier (brokers and forwarders without trucks may self-file), and most use a blanket company covering all states and DC. An invalid process-agent filing is grounds for suspension of operating authority.

The BOC-3 is the least glamorous prerequisite in the authority process and the one most applicants discover last: your $300 is paid, your insurance is filed, and FMCSA still will not issue authority — because nobody can legally serve you court papers yet. That is all the BOC-3 is: a designation, per state, of someone who can receive lawsuits on your behalf.

What it is and who must file

Federal rule 49 CFR 366.109T requires every motor carrier, broker, and freight forwarder to file a designation of process agents before receiving operating authority. An agent must be designated for each state in or through which you operate, and each designated agent must reside in the state for which they are designated — which is why virtually everyone uses a blanket company that designates agents in all states and DC in one electronic filing.

Who is allowed to file it

The rule that surprises applicants: only a process agent can file the BOC-3 on a carrier’s behalf. The single exception is brokers and freight forwarders that operate no commercial vehicles — they may file their own. FMCSA maintains the official list of process-agent companies, and since the Motus rollout, blanket companies manage their agent information through Motus accounts.

FMCSA charges nothing for the filing itself — the process-agent companies charge their own service fees. What you are buying is their agent network and the ongoing validity of the designation.

Not one-and-done

The designation must stay valid for the life of your authority: FMCSA’s registration notice on the subject makes an invalid process-agent filing grounds for suspension of operating authority. If your blanket company exits the business or your filing lapses, the problem surfaces at the worst moment — when someone tries to serve papers, or when FMCSA audits registrations.

Frequently asked questions

What is a BOC-3 in trucking?⌄
The FMCSA filing that designates process agents — parties who can accept legal service (court papers) for your company — in each state where you operate. It is a legal-service requirement, not a safety or insurance filing, and authority cannot be granted without it.
Can I file my own BOC-3?⌄
Only if you are a broker or freight forwarder with no commercial vehicles. Motor carriers must have a process agent file it on their behalf — in practice, a blanket company that designates agents in every state and DC electronically.
When do I file the BOC-3 in the authority process?⌄
After applying for authority and before it can be granted — FMCSA requires the designation on file first, alongside your insurer’s BMC-91/91X filing. Line up a blanket process-agent company as soon as you submit the application.
What happens if my BOC-3 becomes invalid?⌄
FMCSA can suspend your operating authority — the designation must remain accurate for as long as the authority is active. Treat a change of process-agent company like an insurance change: update the filing immediately.
