How State Minimum Requirements Are Structured
Auto insurance minimums are established by each state's legislature and enforced through vehicle registration and traffic laws. Nearly all states require at least bodily injury liability and property damage liability coverage, though a handful operate under no-fault frameworks that also mandate personal injury protection (PIP).
Liability limits are expressed in one of two formats:
- Split limits (most common): Separate caps for per-person bodily injury, total per-accident bodily injury, and property damage — e.g., 25/50/25.
- Combined single limit (CSL): One total dollar amount that applies to all claims from a single accident, without per-person sub-limits.
For a plain-language breakdown of what each coverage type actually does, see our guide to auto insurance coverage types.
New Hampshire and Virginia Are Exceptions
Most states require drivers to carry auto insurance, but New Hampshire has historically allowed drivers to forgo insurance if they can demonstrate sufficient financial responsibility by other means. Virginia has moved toward mandatory insurance requirements in recent years. Both states are outliers — in every other state, carrying at least minimum liability coverage is legally required to register and drive a vehicle.
What State Minimums Cover — and What They Don't
The single most important thing to understand about state minimum coverage is what it excludes. Liability insurance pays for harm you cause to others — their medical bills, lost wages, and vehicle or property repairs. It does not cover:
- Damage to your own vehicle from a collision
- Your own medical expenses after an accident you caused
- Damage from weather, theft, or non-collision events
- Accidents involving uninsured or underinsured drivers (unless you add that coverage separately)
Many drivers assume that carrying insurance means they are covered in any accident. In practice, minimum liability coverage is entirely outward-facing. Understanding where your policy actually stops is essential before an incident occurs.

Average cost of an injury auto claim
Industry data from the Insurance Information Institute indicates that the average bodily injury liability claim regularly exceeds many states' per-person minimum limits.
Why the Minimum Is Often Not Enough
State minimum limits were in many cases set years or decades ago and have not kept pace with the actual cost of medical care or vehicle repair. A single hospitalization from a moderate car accident can easily exceed $50,000 — a figure that surpasses the combined bodily injury limit many states require.
When accident costs exceed your liability limits, the injured party can pursue you personally for the remainder. That could mean your savings, wages, or other assets are at risk.
Consider Limits Relative to Your Assets
A general rule of thumb among insurance professionals is that liability limits should be high enough to protect your financial assets — savings, home equity, future wages — in a worst-case scenario. If your net worth meaningfully exceeds your state's minimum limits, carrying higher limits is worth evaluating. Speak with a licensed agent to assess what level of coverage makes sense for your situation.
Drivers who are financing or leasing a vehicle face a related constraint: lenders typically require both collision and comprehensive coverage — regardless of what state law mandates. This means minimum-only coverage is not an option for most people with auto loans. To think through the trade-offs between liability-only and fuller coverage, see our comparison of liability vs. full coverage.
No-Fault States and Additional Mandatory Coverages
Roughly a dozen states operate under no-fault insurance systems. In these states, each driver's own insurance pays for their medical bills and some lost wages after an accident, regardless of who caused it. This typically requires carrying personal injury protection (PIP) as part of your state-mandated minimum.
Several other states — whether no-fault or traditional — also require uninsured motorist (UM) or underinsured motorist (UIM) coverage as part of their minimums. These coverages protect you when the driver who caused an accident has no insurance or not enough to cover your losses. Given that a significant share of drivers on U.S. roads carry little or no insurance, this protection matters. Our article on uninsured and underinsured motorist coverage explains how these protections work in practice.
Because requirements vary so much by state, checking your own state's Department of Insurance or Motor Vehicles website is the most reliable way to confirm exactly what coverages are legally mandated where you live. Coverage amounts, required add-ons, and penalty structures all differ.

Frequently Asked Questions
You are legally compliant, but your coverage may fall short in a serious accident. If costs exceed your limits, you could be personally responsible for the difference. State minimums do not cover your own vehicle or your own medical expenses.
Yes, significantly. Property damage liability minimums, for example, range from $5,000 in some states to $25,000 or more in others. Some states also mandate additional coverages like PIP or uninsured motorist protection that others do not require.
No. Liability coverage — which is what state minimums require — only pays for damage or injuries you cause to other people and their property. Damage to your own vehicle requires collision or comprehensive coverage, which are not part of state minimum requirements.
Generally yes, but your policy may automatically adjust to meet the minimum requirements of the state you are driving in if those are higher. It is worth confirming this with your insurer, especially for extended travel.
It means the policy pays up to $25,000 for one injured person, up to $50,000 total for all injured people in a single accident, and up to $25,000 for property damage per accident. Any costs beyond those amounts are your responsibility.
