Minimum Coverage Requirements in Massachusetts
Massachusetts requires minimum liability coverage of 20/40/5 ($20,000 bodily injury per person, $40,000 per accident, $5,000 property damage). The state operates under a unique Safe Driver Insurance Plan (SDIP) that assigns points for violations and at-fault accidents, which directly increase insurance premiums through mandatory surcharges. Unlike most states, Massachusetts does not use SR-22 certificates—instead, the Registry of Motor Vehicles (RMV) tracks insurance compliance electronically and assigns surcharges that carriers must apply for up to 6 years after a violation.
How Much Does Car Insurance Cost in Massachusetts?
Massachusetts high-risk insurance rates are driven primarily by the Safe Driver Insurance Plan (SDIP), which assigns points for violations and at-fault accidents. Each SDIP point triggers a surcharge percentage applied to your base premium—minor violations (speeding, lane violations) typically add 2–3 points and increase premiums 20–40%, while major violations (DUI, at-fault injury accidents) add 4–5 points and can raise rates 60–90% or more. Surcharges remain in effect for 6 years from the violation date, and points are cumulative. Massachusetts uses a managed competition system where carriers must file rates with the Division of Insurance, which limits rate variation but means high-risk drivers pay elevated premiums across nearly all carriers.
What Affects Your Rate
- SDIP points and surcharge percentage: each point adds a fixed surcharge that compounds across all coverages
- Type of violation: DUI and leaving the scene carry 5-point assignments and 6-year surcharge periods
- Number of surchargeable events within 6 years: points are cumulative, and 7+ events trigger license suspension
- Territory rating: Boston, Worcester, and Springfield typically carry higher base rates before surcharges are applied
- Carrier willingness: some carriers exit or limit new business for drivers with 4+ points, forcing placement into residual market or specialty carriers
- Time since violation: surcharges remain at full percentage for 6 years but may reduce after 3 years with some carriers
