Massachusetts auto insurance requirements and laws: the minimum coverage explained.

Does Massachusetts require car insurance? Yes, and here’s the minimum

Massachusetts requires compulsory motor vehicle liability insurance. You cannot legally register or operate a vehicle without it. The requirement is governed by M.G.L. c.90 §§34A-34R, and the Division of Insurance enforces it through the registry and the carriers.

Massachusetts is also a no-fault state. That means that regardless of who causes an accident, Personal Injury Protection pays covered medical and wage-loss expenses for the insured, permitted drivers, household members, passengers, and pedestrians. No-fault applies to injury payments, not to property damage or liability.

For policies written or renewing on or after July 1, 2025, the compulsory liability minimum is written in shorthand as 25/50/30: $25,000 per person and $50,000 per accident for bodily injury you cause to others, and $30,000 for damage you cause to someone else’s property. If you stop reading here, that is the core answer. But the minimum is only four required coverages, and each one has limits worth understanding before you rely on it.

The four compulsory coverages and what each one pays

A Massachusetts compulsory policy is built from four coverages. Buy nothing extra, and this is exactly what you have.

Bodily Injury to Others pays when you injure someone in an accident you cause. The compulsory limit is $25,000 per person and $50,000 if more than one person is hurt. Two gaps matter here. This coverage only applies if the accident occurs in Massachusetts, and it does not cover the injury or death of a passenger in your own car.

Personal Injury Protection (PIP) is the no-fault piece. It covers medical expenses, up to 75% of lost wages, and replacement services, up to a combined limit of $8,000. PIP pays for you and the people in your vehicle no matter who caused the crash.

Bodily Injury Caused by Uninsured Auto protects you when the at-fault driver has no insurance. The compulsory minimum is $25,000 per person and $50,000 total for everyone injured by the uninsured vehicle.

Damage to Someone Else’s Property pays when you damage another person’s property, most often their car. The compulsory minimum limit is $30,000.

Notice what is missing. There is no coverage here for damage to your own car, and the bodily injury limits are modest against a serious hospital bill. The minimum keeps you legal. It does not make you whole.

The July 1, 2025 minimum increase under Chapter 275

For decades the Massachusetts minimum was 20/40/5. Chapter 275 of the Acts of 2024 changed that. The act was approved December 23, 2024, and it rewrote the dollar figures inside the statute.

Section 1 amended §34A by striking “at least twenty thousand dollars” and inserting “not less than $25,000.” Section 2 struck “at least forty thousand dollars” and inserted “not less than $50,000.” Section 3 amended §34O, the property damage section, by striking “five thousand dollars” and inserting “$30,000.” That last change is the largest jump, from $5,000 to $30,000 in required property damage coverage.

Section 4 sets the timing. The new limits apply to motor vehicle liability policies issued or renewed on or after July 1, 2025. If your policy renews after that date, the old 20/40/5 minimums no longer exist for you. Any quote or coverage summary that still shows 20/40/5 is out of date.

Penalties for driving without insurance in Massachusetts

The law treats an uninsured vehicle seriously. Under §34J, operating an uninsured motor vehicle, or permitting someone else to operate one you own, is punishable by a fine of not less than $500 nor more than $5,000, imprisonment for not more than one year in a house of correction, or both.

Beyond the criminal penalty, a conviction or guilty plea triggers an automatic 60-day suspension of your license or right to operate, imposed by the registrar. There is a financial obligation on top of the fine. The convicted person is liable to the plan organized under §113H of chapter 175 for the greater of $500 or one year’s premium for compulsory insurance at the highest-rated territory and class. In plain terms, driving uninsured can cost you the fine, your license for two months, and a year of the most expensive compulsory premium the state recognizes.

Why the minimums are not enough, and what to add

The compulsory coverages are a floor, not a plan. Several optional coverages close the gaps built into the minimum.

Optional Bodily Injury to Others raises your limit to $40,000 for one person and $90,000 for everyone hurt, adds coverage for passengers in your car, and extends coverage to accidents that happen outside Massachusetts. If you drive anyone else around or ever leave the state, this fixes two of the biggest holes in the minimum.

Underinsured motorist coverage pays when the at-fault driver has liability limits too low to cover your injuries. Note how it settles: any amount you collect from the at-fault party is deducted from your coverage. With $50,000 per-person underinsured limits, collecting $25,000 from the at-fault driver leaves $25,000 available from your own policy. Our guide on uninsured and underinsured motorist coverage walks through how this stacks in practice.

Optional Medical Payments is available in amounts of at least $5,000 for necessary medical expenses and funeral services, sitting behind PIP.

Collision and comprehensive pay for damage to your own vehicle. They are optional under state law but usually required by a lender if you have a loan. A used private passenger auto may need an inspection before comprehensive is provided, and that inspection can be deferred up to ten calendar days.

Other Massachusetts rules that shape your policy and premium

Several rules unique to Massachusetts affect how your policy is priced and sold.

Massachusetts bars credit-based pricing. M.G.L. c.175 §4E prohibits the use of credit information in issuing or renewing an auto insurance policy. Most states let insurers use credit; Massachusetts does not. We cover the reasoning in why Massachusetts insurers cannot use your credit score.

There is no longer a required standard policy. The standard policy now serves as an advisory filing that insurers may adopt in whole or part and modify, so coverage terms can vary by carrier.

Your driving record drives your premium through the Safe Driver Insurance Plan (SDIP), which your insurer may use to adjust what you pay based on your history. The mechanics of that are in our merit rating guide.

Drivers who cannot find coverage in the voluntary market are covered through the Massachusetts Automobile Insurance Plan (MAIP), also called the Assigned Risk Pool, which assigns them to a carrier.

How to get covered and shop the Massachusetts market

Meeting 25/50/30 is the legal requirement. Building coverage that actually protects you is the real work, and it depends on how each carrier prices your record under the SDIP and how they treat the optional coverages. As an independent brokerage, we shop your risk across carriers, explain where the compulsory minimum leaves you exposed, and bind the policy that fits.
