Car insurance is not the same product everywhere. Each state sets its own minimum coverage limits, decides whether it uses a fault-based or no-fault system, and applies its own rules for what happens when a claim gets disputed. Those differences can change your premium, your coverage needs, and even what you can recover after an accident.
This guide brings together everything on FinSureRes about state-specific car insurance, so you can find your state, understand its rules, and get a quote that actually fits.
Quick Comparison: Fault Systems and Minimum Requirements
| State | System | Minimum Liability | PIP Required? | Unique Rule |
|---|---|---|---|---|
| Massachusetts | No-fault | 20/40/5 | Yes ($8,000) | Bans credit-based pricing |
| Ohio | At-fault | 25/50/25 | No | 51% comparative negligence bar |
| Michigan | No-fault | 250/500/10 (default) | Yes (tiered) | PIP choice + Mini-Tort rule |
| Texas | At-fault | 30/60/25 | Optional | High uninsured-driver rate |
| Indiana | At-fault | 25/50/25 | No | Mandatory UM/UIM by default |
| Maryland | At-fault | 30/60/15 | Yes ($2,500) | Pure contributory negligence |
This table is a starting point, not a substitute for reading the full guide for your state. The details below explain why these differences matter more than they might look at first glance.
No-Fault vs. At-Fault: Why It Matters
In a no-fault state, your own insurance pays your medical bills after an accident, no matter who caused it. Massachusetts and Michigan both use this system, though they structure their PIP requirements very differently. Michigan's system is significantly more complex, with six PIP tiers to choose from, while Massachusetts keeps its PIP requirement fixed at a flat amount.
In an at-fault state, the driver who caused the accident is financially responsible for the damages, and the injured party generally files a claim against that driver's insurance. Ohio, Texas, Indiana, and Maryland all use this model, but they do not treat shared fault the same way.
Why Fault Rules Are the Detail Most Drivers Miss
Two states can both be "at-fault" and still handle a disputed claim completely differently.
● Ohio and Indiana both use a modified comparative negligence rule with a 51 percent bar. You can still recover damages if you are less than 51 percent at fault, just reduced by your share of the blame.
● Maryland uses pure contributory negligence, one of the strictest fault standards left in the country. Being found even 1 percent at fault can bar you from recovering anything at all. This single difference changes how much weight your own PIP, UM/UIM, and collision coverage should carry in a Maryland policy compared to an Ohio or Indiana one.
● Texas technically requires PIP and UM/UIM to be offered by every insurer, but uniquely allows you to reject both in writing, which most other states in this guide do not permit outright.
How to Use This Guide
Find your state below and open the full guide for detailed minimum requirements, average costs, city-by-city rate patterns, and money-saving tips specific to that state.
If you're relocating, read both your old state's guide and your new state's guide, since coverage that met one state's minimum may not automatically satisfy another's.
If you split time between two states, such as a Texas driver who frequently drives in Ohio, understand that your home-state policy still needs to meet whichever state's requirements apply to where the vehicle is registered.
