New Hampshire Commercial Auto Insurance Requirements

RSA 264:20 sets New Hampshire's financial responsibility minimums at 25/50/25 liability for any business that voluntarily carries a policy meeting commercial auto insurance requirements:

• $25,000 for bodily injury or death of one person per accident
• $50,000 for bodily injury or death of two or more people per accident
• $25,000 for property damage per accident

New Hampshire doesn't legally require businesses to buy auto insurance, but uninsured owners who cause accidents have their license and registration suspended under RSA 264:3 until they post security covering the full damages. Most businesses in Nashua, Concord and Manchester carry at least 25/50/25 voluntarily for that reason.

New Hampshire doesn't mandate commercial auto insurance upfront. Under RSA 264, proof of financial responsibility is required only after an at-fault accident or specific traffic violations. The situations below fall outside even that post-incident obligation.

Any vehicle that operates on public roads for business purposes doesn't qualify for these exemptions, even if it also has personal or agricultural uses. Farm trucks driven on Route 16 and construction equipment towed on public highways are both subject to standard financial responsibility requirements. New Hampshire's post-accident review under RSA 264:3 looks at what the vehicle was doing at the time, not what the registration says. Confirm a vehicle's exemption status with the New Hampshire Division of Motor Vehicles before relying on any exemption.

RSA 264:21 gives New Hampshire businesses three methods for proving financial responsibility without a standard commercial auto policy.

• Surety bond: A licensed surety company files a certificate with the New Hampshire DMV meeting 25/50/25 minimums under RSA 264:20. The certificate stays active until 20 days after written cancellation notice per RSA 264:21, I, and annual costs usually run 1% to 3% of the bond amount. Unlike insurance, a surety bond doesn't provide a defense attorney or claims management. The surety pays the claim and then seeks reimbursement from the business.
• Cash or securities deposit: RSA 264:22 allows a deposit of cash or state-approved securities with the State Treasurer matching the 25/50/25 liability levels. Funds stay tied up and inaccessible for as long as the deposit serves as proof of financial responsibility, and any judgment creditor from an accident can execute against the full amount.
• Corporate self-insurance: Corporations can apply to the Director of Motor Vehicles by showing the financial ability to cover liability claims at the 25/50/25 level or above for every registered vehicle per RSA 264:21, III. No statutory net-worth threshold exists, but this option is used primarily by large fleet operators.

RSA 264:21's alternatives satisfy New Hampshire's state-level financial responsibility requirement only. They don't replace federal FMCSA insurance filings for interstate carriers, for-hire passenger operators or hazmat transporters.

Several business situations in New Hampshire create coverage needs beyond the 25/50/25 floor.

New Hampshire enforces commercial auto insurance requirements after at-fault accidents, not through routine traffic stops. The DMV reviews accident reports and requires uninsured drivers to prove financial responsibility under RSA 264 or have their license and registration suspended.

Reinstatement costs add up beyond the table amounts. The $100 license fee (RSA 263:42) and $25 registration fee come on top of the security deposit the director sets under RSA 264:4 to cover actual damages. SR-22 filing is required for a minimum of three years (RSA 264:7, II), and if the SR-22 lapses, the DMV suspends your license again and the three-year clock restarts. Federally regulated interstate carriers also answer to FMCSA enforcement, where penalties can reach $16,000 per day and include operating authority revocation.

Use these steps to confirm your vehicles meet New Hampshire's financial responsibility rules under RSA 264 and any applicable federal requirements.

New Hampshire commercial auto coverage requirements range from the state's 25/50/25 liability floor to $5 million in federal CSL, depending on vehicle use, weight class and whether routes reach into interstate commerce or Canada. Match policy liability limits and vehicle classifications to the requirement tier that applies to each vehicle in the fleet and review coverage when vehicles are added, routes change, or new cargo types are taken on.

Hitting New Hampshire's 25/50/25 is just the baseline. What you actually need comes down to your contracts, what your vehicles are worth and how much you'd be on the hook for in a lawsuit. And if you drive into other states or Canada, check their rules separately.
