Massachusetts is a no-fault state. Drivers must carry at least 25/50/30 + $8,000 PIP in coverage, and the average full-coverage premium is $3,894 a year, 33% above the national average of $2,922. This guide covers what Massachusetts requires, what drivers pay, the rules on fault, uninsured drivers, penalties, teen drivers and phone use, and how to pay less.
| Minimum coverage | 25/50/30 + $8,000 PIP |
| Fault system | No-fault |
| Average full coverage | $3,894 a year ($324 a month), 33% above the national average of $2,922 |
| Uninsured drivers | 7.9% (2023), the 45th highest rate of 51 |
| Filing after serious violations | Proof of financial responsibility, if ordered |
Massachusetts requires $25,000 bodily injury liability per person, $50,000 per accident, $30,000 property damage liability, personal injury protection up to $8,000, and bodily injury caused by an uninsured auto of at least $25,000 per person and $50,000 per accident (Massachusetts Division of Insurance, "Basics of Auto Insurance" and 2025 mandatory coverage limits notice).
| Personal injury protection (PIP) | Up to $8,000 per person for medical expenses, up to 75% of lost wages, and replacement services, whoever caused the crash. |
The minimums are a legal floor, not a recommendation. Property damage limits in particular don't go far when a new car can cost more than the limit to replace, and anything above your limits is your personal responsibility. See how limits and deductibles work and every type of coverage explained.
The average full-coverage premium in Massachusetts is $3,894 a year, 33% above the national average of $2,922. That makes Massachusetts the 2nd most expensive of 49 (48 states plus D.C.; Alaska and Hawaii aren't in the data) (Experian, "Car Insurance Average Costs by State," published September 9, 2026; full coverage, 12 months to August 2026).
Within Massachusetts, prices still vary a lot by ZIP code, driving record and car, and 7.9% of drivers on Massachusetts roads were uninsured in 2023, so the coverage you choose matters as much as the premium.
Your own price depends on your ZIP code, age, driving record, car and coverage. Try our car insurance calculator with Massachusetts preselected for a personal estimate, and see what determines your car insurance cost.
Massachusetts uses modified comparative fault with a 51% bar: your damages are reduced by your share of the blame, and you recover nothing if you are more than 50% at fault. (Matthiesen, Wickert & Lehrer, "Contributory Negligence/Comparative Fault Laws in All 50 States," updated June 10, 2026)
An estimated 7.9% of Massachusetts drivers were uninsured in 2023, the 45th highest rate among the 50 states and D.C. (Insurance Research Council, uninsured motorist estimates for 2023, via Insurance Information Institute "Facts + Statistics: Uninsured motorists"). Uninsured and underinsured motorist coverage protects you when one of them hits you. See coverage types.
Every vehicle registered in Massachusetts must carry the compulsory coverages above for as long as it is registered. (Massachusetts Division of Insurance)
A conviction for operating an uninsured motor vehicle brings a 60-day license suspension, and you become liable for the greater of $500 or one year's premium for compulsory insurance. (Massachusetts General Laws ch. 90 §34J; Mass.gov, "Massachusetts law about auto insurance")
A conviction for driving uninsured also follows you into your next policy. In CarInsurance.com's rate analysis, it raised the average full-coverage premium in Massachusetts from $1,726 to $2,717 a year, an increase of 57% (CarInsurance.com, "Penalty for driving without insurance in every state," updated March 24, 2026; rate analysis).
Beyond the penalties, driving uninsured leaves you personally liable for any damage you cause. See what happens if you drive without car insurance.
If the Massachusetts Registry of Motor Vehicles requires proof of future financial responsibility after a serious violation, your insurer files it, and it must stay in force for the required period.
Massachusetts doesn't allow insurers to use gender or credit-based insurance scores to set car insurance rates, so your driving record, mileage, car and ZIP code carry more weight. (AgentSync (2026); Experian (2026))
Massachusetts uses graduated driver licensing (Insurance Institute for Highway Safety, "Graduated licensing laws" table):
Adding a teen is usually the biggest single increase in a family's premium. Keeping them on the family policy, a good-student discount and a safe, modest car help most.
A distracted-driving ticket can count against your record and your premium. (Insurance Institute for Highway Safety, "Electronic device laws" table)
