Do I need insurance to get an MC number?

Insurance comes after the application, before you can haul

An MC number is assigned when you apply, but the authority stays pending until the required filings are on record. FMCSA states that it will not grant operating authority registration until the registrant has the minimum levels of financial responsibility on file. Hauling for-hire interstate freight while your authority is still pending is not allowed.

Under 49 CFR 365.109T, applicants show financial responsibility by having a Form BMC-91 or BMC-91X (or a BMC-82 surety bond) filed within 20 days of the date the application notice is published in the FMCSA Register. The same rule requires the BOC-3 process agent designation within the same 20 days.

The gap is where most applications stall. A Commercial Carrier Journal analysis of FMCSA’s Motus data, published in September 2026, found that 92.3% of 18,000 pending authority applications had no liability insurance filing on record.

The deadlines from application to active authority

The clock starts when FMCSA publishes a summary of your application in the FMCSA Register, not on the day you apply. If your insurer and process agent miss the 20-day window, FMCSA serves a decision giving you 60 more days to comply before the application is dismissed. Carriers often describe this as a 90-day deadline, which is roughly where the two periods land when counted from the application date.

How much insurance FMCSA requires

The required limit depends on what you haul and how heavy your vehicles are. FMCSA’s insurance filing chart sets these minimums for bodily injury and property damage (BIPD) liability. Federal rules do not require cargo insurance for general freight, only for household goods movers, although many brokers and shippers ask for it in their contracts.

Who files the proof, and how to avoid delays

You cannot file the proof yourself. FMCSA tells carriers not to send insurance certificates to the agency and to have their insurance company submit the filings online. FMCSA advises new applicants to contact their insurer about the filing immediately after receiving their docket number.

A few steps keep the 20-day window from becoming a problem:

• Get quotes before you apply, so you know the premium and down payment you will need. Insurers typically quote on a specific truck and named drivers.
• Use exactly the same business name and address with your insurer, process agent and secretary of state. FMCSA warns that any mismatch delays the grant of authority.
• Order your BOC-3 at the same time; it has the same deadline as the insurance filing.
• Ask your insurer to confirm when the BMC-91 or BMC-91X has been submitted, then check that it appears on your FMCSA record.
• Bind only when you are ready to run. Premiums start when the policy starts, whether or not your authority is active yet.

What it costs to activate an MC number

The government fee is the small part. FMCSA charges $300 per type of authority, which Commercial Carrier Journal notes is nonrefundable under 49 CFR 360.3T. The same analysis concluded that the premium and the down payment needed to get an agent to bind and file are what actually stop most new carriers.

For a sense of scale, Progressive Commercial reports that its 2025 national average for for-hire truck insurance ranged from $734 a month for specialty truckers to $926 a month for other transportation truckers. New authorities with no loss history often pay more than established carriers, and your price will depend on your state, equipment, cargo, radius and driving records.

When you don’t need your own MC insurance filing

Not every truck operator needs an insurance filing with FMCSA:

• Owner-operators leased onto another carrier run under that carrier’s authority and its liability filing. They usually buy their own non-trucking or bobtail liability instead.
• Carriers hauling only exempt commodities without operating authority still need the minimum coverage and an MCS-90 endorsement, but FMCSA says the form does not have to be filed with the agency.
• Intrastate-only carriers do not need FMCSA operating authority, but some states require their own insurance filing, such as a Form E.
• Brokers do not file liability insurance; they file a $75,000 surety bond or trust fund agreement (BMC-84 or BMC-85).

Keeping your authority once it is active

Insurance is not a one-time hurdle. FMCSA requires carriers to keep proof of insurance and a process agent designation on file after authority is granted, and a lapse can lead to revocation proceedings. If you switch insurers, have the new filing in place before the old policy ends.

Because premiums and appetite for new authorities vary widely between insurers, it pays to compare before you apply. A broker such as Florin can compare quotes from several insurers and coordinate the filing once you are ready to bind.
