Auto Insurance Requirements by State

A comprehensive guide to minimum auto insurance requirements in all 50 US states. Understand what coverage you legally need and what experts recommend beyond the minimum.

Understanding State Minimum Requirements

Every state except New Hampshire requires drivers to carry minimum auto insurance coverage. These minimums vary significantly from state to state. The most common requirement is liability insurance, which covers bodily injury and property damage you cause to others. Some states also require personal injury protection (PIP), uninsured/underinsured motorist coverage, or medical payments coverage.

Highest and Lowest Minimum Requirements

Alaska and Maine have among the highest minimum requirements at 50/100/25, meaning $50,000 per person bodily injury, $100,000 per accident bodily injury, and $25,000 property damage. California and Pennsylvania have among the lowest at 15/30/5. The national average for state minimums falls around 25/50/25. Higher minimums generally mean higher base insurance costs in that state.

No-Fault vs. At-Fault States

Twelve states and Washington D.C. have no-fault insurance systems: Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania, and Utah. In no-fault states, your own insurance pays for your medical expenses regardless of who caused the accident. At-fault states allow you to file a claim against the other driver's insurance. No-fault states typically require Personal Injury Protection (PIP) coverage.

Why State Minimums Are Not Enough

State minimum requirements are designed to provide basic protection, but they often fall short of covering real-world accident costs. The average car accident results in $20,000-$50,000 in medical costs, and serious accidents can easily exceed $100,000. If your liability limits are lower than the damages, you are personally responsible for the difference. Financial advisors recommend at least 100/300/100 in liability coverage.
