What Drives Auto Insurance Costs by State?
1. State Insurance Laws
No-Fault vs. Tort States
| System | States | Impact |
|---|---|---|
| No-Fault | FL, MI, NJ, NY, PA, HI, KS, KY, MA, MN, ND, UT | Higher premiums due to PIP requirements |
| Tort (At-Fault) | All others | Generally lower premiums |
Michigan’s unlimited Personal Injury Protection (PIP) historically made it the most expensive state. Recent reforms now allow drivers to choose lower PIP limits.
2. Minimum Coverage Requirements
| State | Liability Minimum | Impact on Base Rates |
|---|---|---|
| California | 15/30/5 | Low minimums = cheaper basic policies |
| Alaska | 50/100/25 | High minimums = higher base rates |
| Texas | 30/60/25 | Moderate requirements |
| Florida | 10/20/10 (PIP) | Low liability, but PIP adds cost |
3. Population Density and Traffic
Urban areas mean more accidents, theft, and vandalism:
| Metro Area | Premium Impact |
|---|---|
| New York City | +45% vs. rural NY |
| Los Angeles | +35% vs. rural CA |
| Miami | +40% vs. rural FL |
| Detroit | +50% vs. rural MI |
| Chicago | +30% vs. rural IL |
4. Weather and Natural Disasters
| Risk Factor | Affected States | Annual Claim Impact |
|---|---|---|
| Hurricanes | FL, LA, TX, NC, SC | +$200-500/year |
| Hail | CO, TX, OK, NE, KS | +$150-300/year |
| Winter storms | Northern states | +$50-150/year |
| Wildfires | CA, OR, WA | +$100-200/year |
5. Uninsured Driver Rates
States with high uninsured motorist rates have higher premiums for insured drivers:
| State | Uninsured Rate | Premium Impact |
|---|---|---|
| Mississippi | 29% | +$200/year |
| Michigan | 26% | +$180/year |
| Tennessee | 24% | +$160/year |
| New Mexico | 22% | +$150/year |
| Florida | 21% | +$140/year |
| National Average | 13% | Baseline |
