Hired and non-owned auto liability insurance for Massachusetts businesses.

What HNOA coverage is and who needs it in Massachusetts

Hired and non-owned auto liability covers two related but distinct exposures. “Non-owned” is the employee who drives a personal vehicle for client meetings, errands, or deliveries; “hired” is any vehicle your business rents, leases, or borrows to conduct business. If either happens at your company, you likely need HNOA, because a Businessowners Policy does not provide any coverage for vehicles at all. A BOP handles your building, your contents, and your general liability exposure; it stops at the curb. The standard vehicle for commercial coverage is the Business Auto Coverage Form, and although it refers only to “autos,” that term is defined broadly to include cars, trucks, trailers, vans, and other vehicles designed for use on public roads. If your business owns no vehicles but your staff drives their own cars on the clock, or you occasionally rent a van for a job, HNOA is the endorsement or policy that closes the resulting gap. A personal auto policy is unlikely to provide coverage if a vehicle is used primarily in business, and it provides no coverage at all for a vehicle actually owned by the business; those need a separate business auto policy.

The gap between an employee’s personal auto policy and your business’s exposure

Here is the mechanism that makes HNOA necessary rather than optional paperwork. When an employee drives a personal car for work and causes an accident, the injured party’s first target is the employee’s own personal auto policy. For a fender-bender, that’s often the end of it. But for a very serious accident, or one with several injured people, the employee’s personal limits frequently aren’t enough to cover the damages, and injured parties then look to collect the remainder from the business itself, since the driving was done on the company’s behalf. At that point the business is a named defendant, and without HNOA in place, there is no commercial policy standing behind the owner. It’s tempting to assume a personal umbrella policy would step in, but it typically excludes claims arising from business use of a vehicle entirely, so it should not be relied on as a backstop for this exposure. Nonprofits get a narrower version of this rule: someone driving a personal auto on nonprofit business generally has coverage under their own personal auto liability policy, but any vehicle the nonprofit owns outright still needs its own business auto policy regardless. For most for-profit Massachusetts employers, the safer assumption is that the gap exists and needs to be closed with a dedicated policy, not inferred from someone else’s personal lines. A refresher on how commercial auto insurance in Massachusetts is structured helps frame where HNOA sits inside that broader policy.

How Massachusetts rates the ‘N’: Non-Ownership Liability under CAR Rule 27

Massachusetts handles Non-Ownership Liability through Rule 27 of the CAR Massachusetts Commercial Automobile Insurance Manual. When this coverage is added, the Business Auto Coverage Form extends protection to the named insured for the use of covered non-owned autos in connection with the business. Rule 27 also allows the coverage to extend further, to cover the individual liability of employees while they’re using their own cars in the employer’s business, with the added premium set in the manual’s Rate Section. That additional premium is a straightforward percentage add-on: the extra cost to extend Non-Ownership Liability to employees is the base premium multiplied by .25. Two structural quirks matter if your business fits either category. Partnerships get a specific rule: when Non-Ownership Liability is in force, the Business Auto Coverage Form extends to cover automobiles owned by individual partners that are used in the business. Social Service Agencies get their own carve-out, letting Non-Ownership Coverage extend either to individual agency employees or to blanket coverage for volunteers who use their own cars in the agency’s programs, priced with separate minimums: $40 Bodily Injury and $10 Property Damage per organization at basic limits, plus $1 per volunteer per coverage, with the option to extend blanket individual liability to volunteers for an added $.50 per volunteer per coverage, subject to an $11 Bodily Injury / $2 Property Damage minimum.

How Massachusetts rates the ‘H’: Hired Automobiles under CAR Rule 28

The hired-auto side of HNOA lives in Rule 28, which covers vehicles that are hired, loaned, leased, or furnished to the insured. Treatment differs depending on whether the insured is providing the primary insurance on that vehicle and whether the lease term runs six months or more, so a short-term rental van and a long-term leased delivery vehicle are not rated the same way. For businesses that regularly rent or lease vehicles as part of operations, premium can be developed on a Cost of Hire Basis under Class Code 66110: the insured estimates its total cost of hiring automobiles in each state where it operates and pays a rate per $100 of that cost of hire. One coverage nuance to flag before you assume everything is bundled: Hired Auto Physical Damage coverage is not cedable, meaning it cannot be placed into CAR’s residual market or reinsurance mechanism, so if a carrier won’t write it voluntarily, the residual market isn’t a fallback for that piece. Organizations that rely on volunteers driving their own vehicles for hired-style arrangements should also know about the Volunteer Hired Autos Endorsement, CA 04 39, which treats volunteers’ vehicles as hired autos for coverage purposes. If rental reimbursement matters to your operation, Rule 33 sets a floor: that coverage is not written for less than 30 days.

Compulsory minimums changed July 1, 2025, and why that raises your HNOA stakes

Massachusetts law under MGL c. 90, §§34A–34R governs compulsory auto liability insurance, and those minimums increased for policies written or renewing on or after July 1, 2025, under Chapter 275 of the Acts of 2024. The current compulsory Bodily Injury to Others minimum is 25/50: at least $25,000 per person and $50,000 if more than one person is hurt. Bodily Injury Caused by an Uninsured Auto carries the same 25/50 minimum, up from the prior 20/40 basic limits shown in CAR’s earlier manuals, which are now superseded. Property Damage liability still requires a minimum limit of $30,000, and Personal Injury Protection remains at $8,000 per person. These numbers matter for HNOA because they are statutory floors, not caps on what your business can be sued for. An employee causing a serious accident while driving for work can still expose the business to damages well above these minimums, which is precisely the layer HNOA and any excess coverage on top of it are built to absorb. When a vehicle is not owned by the person or organization obtaining the insurance, which describes most non-owned and hired situations, CAR’s manual requires a specific Massachusetts mandatory endorsement to be attached to the policy, so a generic out-of-state form doesn’t handle it correctly.

Picking a limit and layering excess coverage over HNOA

Once the compulsory floor is met, the real question is what limit actually protects the business. Unlike personal auto policies with split bodily injury and property damage limits, the Business Auto Coverage Form commonly uses a Combined Single Limit, and the most common commercial auto CSLs for a small business are $500,000 and $1,000,000. Many insurers recommend the $1,000,000 limit, with $500,000 as the practical minimum, because moving up doesn’t add much to the premium relative to the additional protection it buys. If your business carries or plans to carry an umbrella policy, confirm the auto liability policy, including its HNOA piece, is actually listed as an underlying policy on that umbrella; without that listing, the umbrella provides no extension to owned, hired, and non-owned autos even though it’s designed to. Excess and umbrella carriers generally require underlying coverage at certain minimum limits and from insurers meeting financial-strength requirements, so confirm your HNOA limits satisfy whatever your excess carrier requires before assuming the tower is complete. For businesses layering multiple lines, reviewing how umbrella coverage actually attaches is a useful companion to this review.

What to do before your next renewal

HNOA is easy to overlook because it doesn’t attach to a vehicle your business owns; it attaches to activity. Start by inventorying who drives personal vehicles for work and how often, and whether the business rents, leases, or borrows any vehicles during the year. Confirm your current commercial auto policy actually has the Non-Ownership Liability and Hired Automobile pieces in place, not just owned-auto coverage, and check that any umbrella policy correctly lists the auto liability policy as underlying coverage. If your operation involves volunteers driving personal cars, make sure the policy reflects that structure specifically rather than treating volunteers like employees.
