Minimum Car Insurance Requirements by State, Explained

There is no single national car insurance law. Instead, each state decides what drivers must carry, how that must be proven and what happens if you do not comply. Because the details change and differ so widely, this guide explains the concepts rather than listing numbers that could be out of date. For exact figures, use the resources at the end.

What a state minimum is

A state minimum is the lowest amount of coverage the law allows you to carry while driving. In most states this is liability coverage, which pays for injuries and property damage you cause to others. It is a legal floor, set to make sure injured people have some source of payment. It is not designed to cover every cost of a serious accident.

How to read limits like 25/50/25

Liability limits are often written as three numbers. As an example of the format only: a policy written 25/50/25 would mean $25,000 of bodily injury coverage per person, $50,000 per accident for all injured people combined, and $25,000 of property damage coverage per accident. Those figures are just an illustration of how to read the notation, not any state's requirement.

Ways states differ

• Liability limits. The dollar amounts differ by state, and some states have changed them over time.
• Other required coverages. Some states also require uninsured motorist coverage, medical payments or personal injury protection (PIP).
• Fault systems. A number of states use a no-fault approach, where your own policy pays certain injury costs regardless of who caused the crash. Others use an at-fault system.
• Alternatives to insurance. A small number of states allow other ways to demonstrate financial responsibility, though these are uncommon and have conditions.
• Penalties. Driving without required coverage can lead to fines, license or registration suspension, reinstatement fees and higher future premiums, depending on the state.

Why the minimum may not be enough

If you cause an accident and the damages exceed your limits, you may be personally responsible for the difference. Medical bills and vehicle costs can add up quickly. Many drivers choose higher limits than the legal minimum, particularly if they own a home or have savings to protect. An agent can show how the price changes when limits increase.

What to do when you move to a new state

1. Look up the insurance and registration rules for your new state before or soon after you arrive.
2. Tell your insurer about the move. Your current policy may not meet the new state's requirements.
3. Ask for quotes in the new state, since pricing factors and rules may be different.
4. Update your registration and license within the time your new state allows.

How to find the current rules for your state

• Your state department of insurance website, which usually publishes consumer guides
• Your state motor vehicle agency, which covers proof of insurance and penalties
• A licensed agent who writes policies in your state
