Massachusetts uses the SDIP system, not traditional points. Surchargeable incidents stay on your insurance record for 6 years, affecting rates for the first 3 years after conviction.
Massachusetts Uses SDIP Surcharges, Not Traditional Points
Massachusetts does not assign points to violations the way most states do. Instead, the state uses the Safe Driver Insurance Plan (SDIP), which assigns surcharges directly to your insurance premium based on at-fault accidents and moving violations. Each surchargeable incident adds a percentage increase to your base rate — typically 15% to 30% per incident — and that surcharge stays active for 6 years from the incident date.
The SDIP tracks incidents on a 6-year rolling window, but your premium surcharge only applies for the first 3 years after conviction or accident. After 3 years, the incident remains on your SDIP record but no longer affects your rate. After 6 years, it drops off entirely.
This creates a common planning error: drivers assume their rate will drop immediately after 3 years, but carriers don't automatically re-rate policies. You need to request a rate review at renewal after the 3-year mark, or the surcharge may persist on your billing until the next full underwriting cycle.
How the 6-Year SDIP Window Works
Every surchargeable incident — speeding tickets over 10 mph above the limit, at-fault accidents with damage over $1,000, reckless driving citations — is recorded on your SDIP record for 6 years. The clock starts on the date of the incident, not the conviction date or the date you file a claim.
During the first 3 years, the incident triggers a surcharge on your premium. A single speeding ticket adds 2 SDIP points, which translates to roughly a 15% to 20% rate increase. An at-fault accident with injury adds 4 SDIP points, often doubling your premium. After 3 years, the surcharge drops to zero, but the incident still appears on your SDIP record for the next 3 years.
Carriers use the full 6-year record when underwriting new policies. If you switch carriers 4 years after a ticket, the new carrier will see the incident on your SDIP record even though it's no longer surchargeable at your current carrier. Most carriers apply their own lookback rules — typically 3 to 5 years — but they can decline coverage or apply non-standard pricing based on the full 6-year history.
When Your Premium Actually Drops After a Violation
Your premium surcharge expires 3 years after the incident date, but your carrier doesn't automatically lower your rate on that anniversary. Most carriers re-rate policies at renewal, which happens once per policy term — typically every 6 or 12 months. If your 3-year anniversary falls mid-term, the surcharge stays on your billing until the next renewal date.
Request a rate review 30 to 60 days before your renewal date if you're approaching the 3-year mark. Carriers won't volunteer this information, and many drivers pay the surcharge for an extra 6 to 12 months simply because they didn't ask.
Switching carriers after the 3-year mark can accelerate savings. A new carrier will see the incident on your 6-year SDIP record but will price it as a clean-record policy if their underwriting lookback is 3 years or less. Carriers like Plymouth Rock and Safety Insurance write aggressively in Massachusetts and often offer lower rates to drivers exiting the surcharge window.
Multiple Violations and the SDIP Step System
Massachusetts assigns SDIP steps based on your total surchargeable incidents over the rolling 6-year window. Each step increases your premium by a fixed percentage above your base rate. A driver with zero incidents pays base rate (Step 0). One speeding ticket moves you to Step 2, adding roughly 15% to 20%. Two tickets move you to Step 4, adding 40% to 50%. Three or more incidents can push you to Step 9 or higher, where surcharges exceed 100% of base rate.
Steps reset as incidents age out of the 3-year surcharge window, but the reset happens one incident at a time. If you had two tickets in year one and a third ticket in year two, your step drops after 3 years (when the first two tickets exit the surcharge window), then drops again after 4 years (when the third ticket exits). Your premium doesn't return to Step 0 until all incidents are outside the 3-year window.
Carriers apply steps differently. Some use the state's published SDIP table exactly; others apply proprietary surcharge schedules that exceed the state minimums. Commerce Insurance and Arbella Mutual apply higher surcharges than Safety Insurance for the same step, so shopping after each step drop is the highest-leverage action available.
What Counts as a Surchargeable Incident in Massachusetts
Massachusetts considers any moving violation with a fine over $50 or any at-fault accident with damage over $1,000 as a surchargeable incident. Speeding tickets of 10 mph or less over the limit are not surchargeable. Parking tickets, equipment violations, and registration violations do not trigger surcharges.
At-fault accidents are surchargeable regardless of whether you received a citation. If you rear-end another vehicle and the damage exceeds $1,000, the accident adds 3 SDIP points even if no police report was filed. Minor fender benders under $1,000 are not surchargeable, but carriers may still consider them during underwriting if the claim appears on your CLUE report.
Defensive driving courses do not remove SDIP surcharges in Massachusetts. The state does not offer point reduction for course completion the way Florida or California does. The only path to lower rates is waiting out the 3-year surcharge window or shopping carriers with more favorable step pricing.
How Carriers Price SDIP Steps Differently
Massachusetts mandates minimum SDIP surcharges, but carriers can apply higher percentages. A Step 4 driver (two surchargeable incidents) might see a 40% surcharge at Safety Insurance and a 65% surcharge at Commerce Insurance for the same policy. This variation creates a 20% to 30% rate difference between carriers for drivers with active surcharges.
Preferred carriers like Arbella and Plymouth Rock decline drivers at Step 6 or higher, routing them to standard or non-standard markets. MAPFRE and Commerce Insurance write standard policies up to Step 9 but apply higher base rates. Non-standard carriers like Dairyland and Bristol West write policies at any step but price them 50% to 100% above standard market rates.
Shopping after each step drop is critical. A driver moving from Step 6 to Step 4 may qualify for preferred pricing again, cutting their premium by 30% to 40% overnight. Carriers don't notify you when you drop a step — you need to request quotes at renewal after each 3-year anniversary.
SDIP and License Suspension in Massachusetts
Massachusetts does not suspend licenses based on SDIP steps alone. The state suspends licenses for specific violations — driving to endanger, reckless driving, leaving the scene of an accident — or for accumulating 3 surchargeable speeding violations within 12 months. A driver can reach Step 9 without facing suspension as long as no individual violation crosses the reckless or habitual offender threshold.
Suspensions for 3 speeding tickets in 12 months last 30 days. After reinstatement, you must file proof of insurance with the RMV, but Massachusetts does not require SR-22 filing for points-based suspensions. The suspension adds a major incident to your SDIP record, which carriers treat as a 5-point surcharge on top of the underlying tickets.
Hardship licenses are not available for SDIP-related suspensions in Massachusetts. If you're suspended for habitual speeding, you lose driving privileges entirely for the suspension period. The only path to early reinstatement is appealing the suspension through the RMV's Board of Appeal, which succeeds only when procedural errors occurred during the original citation process.
