Article 19: How Much Liability Coverage Do You Actually Need?

Every state sets a legal minimum for liability insurance, but “legal” and “adequate” are two very different things. Figuring out how much liability coverage actually makes sense for you requires looking past the minimum requirement and thinking honestly about your financial exposure.

Why the State Minimum Often Isn’t Enough

State minimum liability limits were generally set with an eye toward affordability and basic legal compliance, not toward fully protecting drivers or accident victims from the real cost of a serious crash. Modern medical care and vehicle repair costs can easily exceed low liability limits after a serious accident, leaving an at-fault driver personally on the hook for whatever their insurance doesn’t cover. many states still set limits like 25/50/25 that were established decades ago, while a serious injury claim today can easily exceed $100,000

In other words, carrying only the state minimum is legal, but it may not actually protect your finances the way you’d assume “having insurance” would.

What Happens When Liability Limits Are Exceeded

If you cause an accident and the resulting bodily injury or property damage claims exceed your liability limits, your insurance company will pay up to your policy’s limit — and then stop. Anything beyond that becomes your personal financial responsibility. This can mean:

• The injured party (or their insurer) pursuing a lawsuit against you personally for the remaining balance
• Wage garnishment, liens on property, or other collection actions, depending on your state’s laws and the size of the judgment
• Years of financial strain paying off a judgment that your insurance didn’t fully cover

This is the core risk that higher liability limits are designed to protect against.

Key Factors to Consider When Choosing Your Limits

1. Your Assets

The more you have to lose — savings, home equity, investments — the more a lawsuit could realistically target if your liability limits fall short. Higher-asset individuals generally benefit from higher liability limits (and sometimes an umbrella policy on top) to protect what they’ve built.

2. Your Income

Future wages can potentially be garnished to satisfy a judgment in many states, so even if you don’t have significant assets today, higher future earning potential is worth protecting.

3. Your Driving Exposure

The more you drive — long commutes, road trips, driving for work — the more accident opportunities you’re exposed to over time, which increases the statistical odds you’ll eventually need your liability coverage to perform.

4. Who’s on Your Policy

If you have teen drivers or other higher-risk drivers on your policy, your overall risk of a serious claim goes up, which strengthens the case for higher limits.

5. Where You Live

Accident costs, medical costs, and legal environments vary by region, which can affect how far a given liability limit actually stretches. accident and repair costs can vary by 30% or more between regions depending on local labor rates, cost of living, and the legal environment

A Common Rule of Thumb (Use With Caution)

Some financial advisors suggest carrying liability limits roughly equal to your net worth, on the theory that you’re protecting exactly what a lawsuit could realistically take from you. This is a reasonable starting framework, but it has limits of its own — a catastrophic injury claim can exceed almost anyone’s net worth, so this rule shouldn’t be treated as a hard ceiling on how much coverage makes sense. it’s worth consulting a licensed insurance agent or financial advisor for personalized guidance on appropriate limits

Understanding Split Limits vs. Combined Single Limits

Liability coverage is often structured as “split limits” — separate caps for per-person bodily injury, per-accident bodily injury, and property damage (e.g., $100,000/$300,000/$100,000). Some insurers also offer a combined single limit (CSL), which provides one lump-sum cap that applies across both bodily injury and property damage combined, offering more flexibility in how the payout is allocated. Which structure is available, and which makes more sense, depends on your insurer and personal preference. combined single limit (CSL) policies are less common than split limits, but a number of major insurers offer them, particularly on higher-limit or umbrella-eligible policies — ask your agent whether it’s available on your policy

The Case for Pairing Higher Liability Limits With an Umbrella Policy

For drivers with significant assets or high-risk exposure, an umbrella policy can provide an additional layer of liability protection above and beyond your auto policy’s limits, often at a relatively modest cost given how much extra protection it adds. Umbrella policies typically require you to carry a minimum level of underlying liability coverage on your auto policy first, so raising your auto liability limits is often a prerequisite step before adding one. most umbrella policies require underlying auto liability limits of at least $250,000/$500,000 (sometimes $300,000/$300,000), and a $1 million umbrella policy typically costs around $150 to $300 per year

A Practical Framework for Deciding

1. Start with your state’s minimum as the legal floor, not the target.
2. Add up your assets and consider your future income to estimate what a lawsuit could realistically pursue.
3. Consider your specific risk factors — commute length, teen drivers, driving history.
4. Compare the cost difference between minimum limits and significantly higher limits — liability coverage increases are often more affordable per additional dollar of protection than people expect, since higher limits mainly matter in the less-frequent, larger-claim scenarios.
5. Talk to a licensed agent about whether an umbrella policy makes sense alongside higher auto liability limits.

The Bottom Line

The state-mandated liability minimum is a legal requirement, not a financial safety recommendation. How much liability coverage you actually need depends on your assets, income, driving exposure, and risk tolerance — and for many drivers, that number is meaningfully higher than the legal floor. Reviewing your limits periodically, especially after major life changes like buying a home or a significant increase in income, is a smart habit for keeping your coverage aligned with what you actually have to protect.
