Do auto insurance requirements differ by state?

Yes. Every state sets its own minimum liability limits, decides whether to use a fault or no-fault system, and determines which coverages are mandatory beyond liability. Requirements can vary significantly — Florida's minimums are much lower than Michigan's, for instance.

What is the difference between fault and no-fault states?

In fault (tort) states, the driver who caused the accident is responsible for the other party's damages. In no-fault states, each driver's own insurance pays their own medical bills regardless of fault, which is why PIP is mandatory in those states.

An SR-22 is a certificate of financial responsibility that your insurer files with your state's DMV. It's required after certain violations — DUIs, license suspensions, uninsured accidents — to prove you carry at least the minimum required insurance.

How state auto insurance laws work

Each state government sets the minimum insurance a driver must carry to legally register and operate a vehicle. Those minimums vary widely: some states require only basic liability; others mandate PIP, uninsured motorist coverage, or both.

Understanding your state's rules prevents surprises when you file a claim or renew a policy after moving.
