Maine Fault System — FAQ
Is Maine a no-fault state?
+
Maine is an at-fault (tort) auto insurance state. In an at-fault (tort) state, the driver who causes a crash — through their liability insurance — is responsible for the other party's injuries and damage, and you retain the full right to sue the at-fault driver. Among the highest minimum BI liability limits in the nation (tied with Alaska at 50/100).
Does Maine require PIP or uninsured-motorist coverage?
+
Maine does not mandate PIP in its minimum auto policy, though many insurers offer it (and MedPay) as an add-on. Uninsured/underinsured motorist bodily-injury coverage of $50,000/$100,000 is part of the state minimum.
Why does it matter whether Maine is no-fault or at-fault?
+
It changes who pays and whether you can sue. In a no-fault state your own PIP pays your medical costs first and lawsuits are limited to serious injuries; in an at-fault state the at-fault driver's liability insurance pays and you keep the full right to sue. This affects which coverages you should carry. This is general information, not legal advice — confirm specifics with the Maine Department of Insurance or a licensed attorney.
