Minimum Coverage Requirements in Massachusetts
Most Massachusetts auto insurance carriers will non-renew your policy after a DUI conviction or serious violation — they typically wait until your policy term ends rather than canceling immediately, giving you 30–90 days to find replacement coverage. The Massachusetts Registry of Motor Vehicles (RMV) requires you to maintain SR-22 filing for 3–5 years after license reinstatement, depending on the violation. You must carry at least the state minimum liability limits (20/40/5) continuously during this period, and your insurer must file proof of coverage electronically with the RMV.
How Much Does Car Insurance Cost in Massachusetts?
Auto insurance premiums in Massachusetts increase 50–200% after a DUI or serious violation, depending on offense severity, prior driving history, and whether you have additional violations. A first-offense DUI typically increases rates by 70–120%, while repeat offenses or violations involving injury can double or triple premiums. Massachusetts uses the SDIP surcharge system, which assigns points to violations and keeps surcharges active for 6 years from the violation date.
What Affects Your Rate
- Violation type and severity (first-offense DUI vs. repeat offense vs. refusal)
- SDIP surcharge points assigned to the violation (typically 5 points for DUI, active for 6 years)
- Prior driving history and whether you have additional violations within the surcharge period
- Whether you maintained continuous coverage or had a lapse before or after the violation
- Carrier availability — Massachusetts has fewer non-standard carriers than many states, limiting competitive pricing
- Geographic location within Massachusetts — urban areas like Boston have higher base rates than rural counties
