Massachusetts car insurance requirements and laws

Minimum car insurance requirements

Massachusetts was the first state to require auto liability insurance, and in 2025 it raised its compulsory limits for the first time since 1988. Chapter 275 of the Acts of 2024, signed in December 2024, increased the minimums for policies issued or renewed on or after July 1, 2025. The Division of Insurance's filing guidance (Notice 2025-A) lists the new limits for the four compulsory parts of the Massachusetts policy. Compare states with the state car insurance requirements lookup.

Some early press coverage said the uninsured motorist minimum stayed at 20/40; the Division of Insurance's own guidance lists 25/50, and that is the figure used here. A policy in force before July 1, 2025 keeps its old limits until it renews.

What the minimums mean in practice. If you cause a crash and the other driver has $40,000 in medical bills and lost wages, their PIP pays the first $8,000, and they can claim the rest from you. Your 25/50 coverage pays up to $25,000, leaving about $7,000 that could come from you personally. The old $5,000 property damage limit would barely cover a bumper; $30,000 is better but still short of the cost of many new SUVs. how much liability coverage do you need? and the liability limits decoder can help.

Fault system and what it means after a crash

Massachusetts is a no-fault insurance state. Each injured person's PIP pays medical bills, lost wages and replacement services up to $8,000, whoever caused the crash. You can sue the at-fault driver for pain and suffering only if your reasonable medical expenses exceed $2,000 or the injury causes death, loss of a body member, permanent and serious disfigurement, certain loss of sight or hearing, or a fracture (G.L. c. 231 §6D). See no-fault vs at-fault states and tort threshold.

Vehicle damage is handled outside no-fault, through the at-fault driver's property damage liability or your own collision coverage. When both drivers share blame, Massachusetts uses modified comparative negligence: you recover only if your negligence was not greater than that of the people you sue, and your damages are reduced by your share (G.L. c. 231 §85). Most tort suits must be filed within three years (G.L. c. 260 §2A; statutes of limitations for car accident claims).

At-fault accidents also count against you through the state's Safe Driver Insurance Plan, which adds surcharge points to your premium for at-fault crashes and traffic violations (surcharge).

Optional coverage worth considering here

• Optional bodily injury to others above the 25/50 minimum. Many drivers carry 100/300 or more.
• Higher uninsured and underinsured motorist limits. The Insurance Research Council estimates 7.9% of Massachusetts drivers were uninsured in 2023, well below the national 15.4%, but underinsured drivers with minimum limits remain common (uninsured and underinsured motorist coverage explained).
• Medical payments to extend coverage beyond PIP's $8,000 (Medical payments coverage (MedPay) explained).
• Collision and comprehensive. Nor'easters, snow, potholes and theft make physical damage coverage worth considering on any car you could not easily replace.

What drives rates in Massachusetts

The NAIC puts the state's average annual expenditure at $1,326 in 2023, slightly above the national average of $1,282 (What NAIC auto insurance data measures).

Greater Boston's dense traffic, high repair labor rates and high medical costs push claims up, and winter weather adds collision losses. Massachusetts limits which factors insurers may use, and rates are tied heavily to your driving record through the Safe Driver Insurance Plan. The higher 2025 minimums raised the price of a minimum policy, though most drivers already carried more. Rates vary sharply by town (Why your ZIP code changes your car insurance price).

Penalties for driving uninsured

Operating, or letting someone operate, a vehicle without the required policy is punishable by a fine of $500 to $5,000, up to one year in a house of correction, or both (G.L. c. 90 §34J). A person convicted is also liable to the state's residual market plan for the greater of $500 or one year's premium for the highest-rated territory and class. The Registry of Motor Vehicles can also suspend registrations and licenses. See penalties for driving without insurance.

SR-22 and high-risk drivers

Massachusetts does not rely on SR-22 filings for its own drivers the way many states do; insurers report coverage directly to the RMV. Drivers with poor records pay through Safe Driver surcharges, and anyone refused coverage can get a policy through the Massachusetts Automobile Insurance Plan (MAIP), the assigned risk plan run by Commonwealth Automobile Reinsurers (assigned risk plans: insurance of last resort, high-risk car insurance: options when insurers say no). If another state ordered you to keep an SR-22, keep it current after you move.

Insurers with a strong presence in Massachusetts

Massachusetts has its own market leaders. MAPFRE Insurance, through the Webster-based Commerce Insurance Company, has long been the largest writer, alongside locally based Arbella Insurance, Safety Insurance, Plymouth Rock Assurance, Liberty Mutual, Quincy Mutual and The Hanover. Rhode Island's Amica is also a significant writer. Some large national carriers have a limited presence here. See regional car insurers: when smaller carriers can beat the giants.
