Massachusetts SR-22 After an OUI — Do You Need One?

JD Updated August 2026 · Verified against Massachusetts RMV guidance
Massachusetts does not require SR-22 insurance. Massachusetts runs a compulsory-insurance system — every driver is required to carry insurance, and compliance is verified through the RMV and vehicle registration process. There is no SR-22 certificate filing required after an OUI. What you do need is to maintain your existing compliant insurance policy and, if Melanie’s Law applies to you, enroll in the RMV Ignition Interlock Device Program.

If you found this page searching for “Massachusetts SR-22 after OUI,” you don’t need one within Massachusetts. However, if you need to reinstate a license in another state that requires SR-22 (for example, if you previously held a license in a state that does use SR-22), that state’s rules would apply — confirm with that state’s DMV.

What you actually need after a Massachusetts OUI

Massachusetts’s compulsory-insurance law (M.G.L. c.90 §34A) requires every driver to carry minimum liability coverage. An OUI conviction doesn’t change what type of insurance filing you need — you maintain your standard policy. What it does affect:

  • Your premium: An OUI conviction is a major rating factor. Expect a significant increase at renewal, even without an SR-22.
  • Your carrier: Some standard insurers won’t renew after an OUI. You may need to shop for a carrier willing to write a post-OUI policy at renewal.
  • Your IID enrollment (if applicable): Second and subsequent offenders and .15%+ first-offense hardship-license seekers must enroll in the RMV IID program — see below.
Your OUI will still raise your premium. Even without an SR-22, a conviction is a major rating factor at every insurer. Comparing quotes from carriers that specialize in post-OUI coverage can meaningfully lower what you pay at renewal. Compare quotes →

Do you need the ignition interlock?

If you’re a second or subsequent OUI offender, or a first offender with a .15%+ breath test seeking a hardship license, Melanie’s Law requires enrollment in the RMV IID program. The minimum term is 2 years (730 compliant days) post-reinstatement. Qualifying drivers can get the device at no cost through the RMV Indigency Program.
