liability car insurance coverage: 7 Powerful Must-Know Facts 2025
Understanding Your Financial Protection on the Road
Liability car insurance coverage is the foundational protection that pays for damages you cause to others in an auto accident. Here’s what you need to know:
| Liability Coverage Type | What It Covers | What It Doesn’t Cover |
|---|---|---|
| Bodily Injury Liability | Medical bills, lost wages, pain and suffering, and legal defense costs for injuries you cause to others | Your own injuries |
| Property Damage Liability | Repair costs for other vehicles, structures (fences, buildings), and property you damage | Damage to your own vehicle |
Liability car insurance is legally required in almost every state, though minimum requirements vary. It serves as your financial safety net when you’re at fault in an accident, protecting your savings and assets from being seized to pay for damages that exceed your coverage limits.
Key points about liability coverage:
- It’s expressed as three numbers (like 100/300/50), representing thousands of dollars in coverage limits
- The first number is bodily injury per person
- The second is bodily injury per accident
- The third is property damage per accident
The average cost of liability-only car insurance in 2025 is about $736 per year or $61 per month for a 35-year-old driver with good credit and a clean driving record.
While liability insurance protects others from your mistakes, it does not cover damage to your own vehicle or your personal injuries — for that, you’d need collision and comprehensive coverage.

Understanding Liability Car Insurance Coverage
Liability car insurance coverage is the foundation of your auto policy – it’s the part that steps in when you’re responsible for an accident. Think of it as your financial safety net when things go wrong on the road.
When you’re cruising through Massachusetts or taking that scenic drive along the New Hampshire coastline, your liability coverage is quietly protecting your financial future. It’s not just something you’re required to have by law – it’s what stands between you and potentially losing your savings, home, or other assets after a serious accident.
“Many drivers focus on the price tag without understanding what they’re actually buying,” says Chris Donovan, a veteran agent at Stanton Insurance Agency. “Liability coverage doesn’t just pay for damages—it also provides legal representation if someone takes you to court after an accident.”
Liability Car Insurance Coverage Basics
At its heart, liability car insurance coverage protects others from the financial impact of your mistakes behind the wheel. It’s called “third-party” coverage because it pays for people outside your policy – not you or your insurance company.
When you accidentally rear-end someone at a stoplight or slide through an intersection in winter weather, your liability coverage kicks in to help the other party recover. It covers their losses when you’re legally responsible (or “liable”) for the accident.
The Insurance Information Institute recommends carrying liability limits of at least $100,000/$300,000/$50,000 – significantly higher than most state minimums. This isn’t just cautious advice; it reflects the real costs of accidents in today’s world of expensive medical care and vehicle repair costs.
Bodily Injury vs. Property Damage
Your liability car insurance coverage comes in two distinct flavors, each serving a critical purpose:
Bodily Injury Liability covers people who are hurt when you cause an accident. This isn’t just about immediate medical bills – it can include ongoing care, lost wages while someone recovers, and even compensation for pain and suffering. If the worst happens and someone passes away, it can cover funeral expenses. It also pays for your legal defense if you’re sued.
A real example: Tom was distracted by his GPS and ran a stop sign, hitting a cyclist. His bodily injury coverage paid for the cyclist’s emergency room visit, surgery, physical therapy, and the wages lost during six weeks of recovery.
Property Damage Liability handles the things you damage in an accident. This most commonly means other vehicles, but it extends to anything your car might hit – mailboxes, fences, storefronts, or even expensive roadside equipment like traffic signals.
Consider this scenario: Maria lost control on an icy road and slid into a parked car, pushing it through a neighbor’s wooden fence. Her property damage liability covered repairs to both the car and fence, plus a rental car for the owner while their vehicle was in the shop.
While liability car insurance coverage protects others, it doesn’t cover your own car or injuries. That’s why many drivers choose to add comprehensive, collision, and medical payments coverage for complete protection.
What Liability Insurance Covers—and What It Doesn’t
Let’s clear up a common confusion about liability car insurance coverage – while it’s absolutely essential protection, it doesn’t cover everything. Understanding these boundaries helps you make smarter decisions about your overall insurance needs.
Covered Expenses & Scenarios
When you’re at fault in an accident, your liability car insurance coverage steps in like a financial guardian angel – but only for the other people involved.
For the people you’ve injured, your bodily injury liability pays for their immediate emergency care, including that expensive ambulance ride and ER visit. It continues covering their hospital stays, surgeries, and ongoing treatment as they recover. If they can’t work during recovery, your coverage helps replace their lost wages. In serious cases, it even compensates for their pain and suffering.
Here’s a real-world example we encountered last year: A client was momentarily distracted by her GPS and ran a stop sign, hitting a family’s SUV. The other driver suffered whiplash, while his passenger had a broken wrist. Our client’s liability car insurance coverage paid for both victims’ medical treatments, their physical therapy, and the husband’s missed work days – totaling nearly $28,000.
For property damage, your coverage handles repairs to other people’s vehicles, buildings, fences, or public property like guardrails. If someone’s car is totaled in an accident you cause, your liability insurance pays to replace it (up to your limits). It even covers less obvious damages like torn-up landscaping or personal items that were in their vehicle.
Your policy also provides something invaluable – legal defense. If you’re sued after an accident, your insurer will pay for your attorney and court costs, which can easily run into tens of thousands of dollars.
What Liability Car Insurance Coverage Will NOT Pay For
Here’s where many drivers get confused. Despite its importance, liability car insurance coverage has clear limitations:
Your own vehicle damage isn’t covered when you cause an accident. That fender you crumpled? The door that won’t close properly now? That’s on you unless you have collision coverage.
“I regularly speak with clients who are shocked to learn their liability insurance won’t fix their own car,” says Angela Reyes, a claims specialist at Stanton Insurance Agency. “I have to explain that liability insurance doesn’t cover your car if you hit someone – it only protects the other party.”
Your own medical bills aren’t covered either. If you break your arm in an accident you caused, your liability insurance won’t pay for your cast, medication, or physical therapy. For that protection, you’d need medical payments coverage or personal injury protection.
Other exclusions include theft or vandalism to your vehicle, weather-related damage like hail or flooding, and mechanical failures. These non-collision incidents require comprehensive coverage instead.
Liability Car Insurance Coverage in Hit-and-Run or No-Fault Cases
Hit-and-run accidents create complicated situations. If someone hits you and disappears, their liability insurance should cover you – but since they’re gone, you can’t access it. In these cases, your own uninsured motorist coverage becomes your safety net. Without it, you’ll be relying on your collision coverage (if you have it) and your health insurance for medical expenses.
In no-fault states like Massachusetts, the system works differently. Each person’s Personal Injury Protection (PIP) coverage pays for their own medical expenses regardless of who caused the accident. However, property damage claims still operate on a fault basis, so liability car insurance coverage remains essential for vehicle repairs.
Even in no-fault states, serious injuries can exceed PIP limits or meet thresholds that allow victims to step outside the no-fault system and sue the at-fault driver. When this happens, robust liability limits become your financial shield against potentially devastating lawsuits.
While state minimums satisfy legal requirements, they rarely provide enough protection for serious accidents. We recommend coverage limits that align with your assets and financial situation – because adequate liability car insurance coverage isn’t just about meeting legal obligations; it’s about sleeping soundly knowing you’re properly protected.
Limits, State Minimums & Costs
When it comes to liability car insurance coverage, understanding your policy limits isn’t just important—it’s essential for protecting your financial future. These limits represent the maximum amount your insurance company will pay if you’re responsible for an accident, and choosing the right ones can make all the difference.
How Coverage Limits Work
Liability car insurance coverage limits typically appear as three numbers on your policy—something like 25/50/25 or 100/300/50. Don’t worry if this looks like a secret code; it’s actually pretty straightforward:
- The first number is the maximum your insurer will pay for bodily injury to any one person (in thousands)
- The second number is the maximum for all injuries in a single accident (in thousands)
- The third number is the maximum for property damage in an accident (in thousands)
Let me bring this to life with a real example. Imagine you have a 50/100/50 policy and cause an accident involving a family of four. The father needs $75,000 in medical care, the mother needs $40,000, and each child needs $20,000. Their car, worth $30,000, is totaled.
Your coverage would pay $50,000 for the father (your per-person limit), leaving him with $25,000 in unpaid bills. The mother’s $40,000 would be fully covered. But here’s where it gets tricky—you’ve now used $90,000 of your $100,000 per-accident limit, leaving only $10,000 for both children’s combined $40,000 in bills. The car repair would be fully covered under your $50,000 property damage limit.
The sobering reality? You’d be personally responsible for the remaining $55,000 in medical expenses. This is why choosing appropriate limits is so crucial—and why state minimums rarely provide adequate protection.
Some insurers offer combined single limit (CSL) policies, which provide one overall limit instead of separate ones. With a $300,000 CSL, you’d have up to $300,000 to cover all damages in an accident, whether they’re bodily injuries or property damage.
Minimum Liability Requirements by State
Each state sets its own minimum liability car insurance coverage requirements, and they vary significantly. Here in New England, the requirements for our three primary states look like this:
| State | Bodily Injury (per person/per accident) | Property Damage | Additional Requirements |
|---|---|---|---|
| Massachusetts | $20,000/$40,000 | $5,000 | PIP: $8,000 |
| New Hampshire* | $25,000/$50,000 | $25,000 | MedPay: $1,000 |
| Maine | $50,000/$100,000 | $25,000 | MedPay: $2,000 |
*New Hampshire has a unique approach—it doesn’t legally require auto insurance, but drivers must prove they can pay for damages if they cause an accident. Most folks choose insurance over risking their savings and home.
Maine’s requirements are among the highest nationally, while Massachusetts has a surprisingly low property damage minimum of just $5,000—which wouldn’t even cover a fender-bender with a newer vehicle.
For a complete breakdown of requirements nationwide, the Insurance Information Institute maintains an up-to-date list.
How Much Liability Car Insurance Coverage Do You Need?
Meeting state minimums keeps you legal, but it’s like wearing a life jacket in a hurricane—technically protective, but not nearly enough. At Stanton Insurance, we believe your liability car insurance coverage should reflect your actual financial situation.
A simple way to think about it: your liability limits should at least match your net worth. This includes your home equity, savings, investments, future income potential, and other valuable assets.
“State minimums are like ordering the smallest size at a restaurant when you’re starving,” states Amber Lee, a senior agent at Stanton Insurance Agency. “They might technically feed you, but you’ll still be hungry—and vulnerable.”
For most of our clients across Massachusetts, New Hampshire, and Maine, we typically recommend at least 100/300/100 coverage. These limits provide substantially better protection than state minimums and often cost just a little more each month—sometimes just the price of a coffee or two.
If you’ve built significant wealth or assets, we might suggest even higher limits or adding an umbrella policy that extends your liability protection beyond your auto insurance limits, giving you that extra layer of security.
What Determines the Price of Liability Coverage
The cost of your liability car insurance coverage depends on a variety of factors that insurers use to calculate your risk profile.
Your personal details matter significantly—your age, driving history, credit score (where legally allowed), marital status, gender, how much you drive, and where you live all influence your rates. A clean driving record can save you hundreds each year, while even a single speeding ticket might bump up your premium.
Your vehicle plays a role too. The make, model, age, safety features, and how you use it (commuting vs. occasional pleasure driving) all factor into your rate calculation.
Policy choices also affect your premium—higher coverage limits will cost more, though often not proportionally so. Doubling your coverage rarely doubles your premium. Bundling with homeowners or renters insurance typically earns you a discount, as does paying your premium in full rather than monthly.
On average, liability car insurance coverage costs about $736 annually for a 35-year-old with good credit and a clean driving record. But this can vary dramatically based on all these factors.

While price is important, the right coverage is priceless when you actually need it. As we often tell our clients, “Insurance is expensive until you need it—then it’s a bargain.”
Liability-Only vs. Full Coverage: Which Is Right for You?
When shopping for auto insurance, one of the biggest decisions you’ll face is whether to purchase liability car insurance coverage only or to add comprehensive and collision coverage for what’s commonly called “full coverage.” This choice can significantly impact both your monthly premium and your financial security after an accident.
Pros & Cons of Liability-Only Policies
Choosing a liability-only policy comes with some clear advantages. Lower premiums are the most obvious benefit—you’ll typically pay 60-70% less than you would for full coverage. That’s a significant saving that might free up room in your monthly budget for other expenses.
There’s also a simplicity factor with liability-only coverage. Fewer coverage options mean less complexity when managing your policy or filing a claim. And if you’re driving an older vehicle worth less than $3,000, liability-only coverage often makes financial sense. Why? Because over a few years, the extra premium you’d pay for full coverage might actually exceed your car’s total value.
“I had a client with a 15-year-old pickup truck who was paying nearly $800 a year for full coverage,” shares Mark Evans, an agent at Stanton Insurance Agency. “When we calculated that his truck was worth about $2,500, we realized he was effectively buying his truck again every three years through his insurance premiums!”
Of course, liability-only coverage isn’t without its downsides. The most significant drawback is having no protection for your own vehicle. If you cause an accident that totals your car, you’ll be completely on your own for replacement costs. Similarly, if your car gets stolen or damaged in a hailstorm, you’ll have zero coverage without comprehensive insurance.
This creates a substantially higher financial risk that you need to be comfortable accepting. And it’s worth noting that if you have a car loan or lease, liability-only simply isn’t an option—lenders and leasing companies will require full coverage to protect their investment in your vehicle.
When to Upgrade to Full Coverage
There are several situations where upgrading from liability car insurance coverage makes good financial sense. First, consider your vehicle’s value. If your car is worth more than $3,000, full coverage often provides important protection that justifies the higher premium. This is especially true for newer vehicles where repair costs can quickly reach thousands of dollars.
Your personal financial situation matters too. If you couldn’t easily replace your vehicle out-of-pocket after a total loss, full coverage provides valuable peace of mind. Many of our clients find that the slightly higher monthly premium is worth knowing they won’t face a transportation crisis after an accident.
As mentioned earlier, if you have a car loan or lease, your decision is already made for you—your lender will require full coverage. But even if you own your car outright, your living situation might warrant better protection. Do you live in an area with frequent hailstorms? High theft rates? Regular flooding? These high risk factors make comprehensive coverage particularly valuable.
Sometimes, the cost difference between liability-only and full coverage is smaller than you might expect. When you factor in multi-policy discounts and safe driver reductions, comprehensive and collision coverage might add less to your premium than anticipated. This is especially true if you’re bundling with homeowners or renters insurance.
Here’s a helpful calculation we often share with clients: If the annual cost of adding comprehensive and collision coverage exceeds 10% of your vehicle’s value, liability-only coverage might make financial sense. For example, if your car is worth $5,000, and adding full coverage would cost more than $500 per year above your liability premium, you might consider sticking with liability only.

Special Scenarios & No-Fault Nuances
When it comes to liability car insurance coverage, not every situation fits neatly into the standard framework. Let’s explore some special circumstances that might affect how your coverage works – because understanding these nuances could save you from a financial nightmare down the road.
What Happens If Damages Exceed Your Limits
Here’s a scenario that keeps me up at night as an insurance agent: A client causes a serious accident, and the damages far exceed their policy limits. Unfortunately, this happens more often than you’d think.
When your liability car insurance coverage isn’t enough to cover all the damages:
- Your insurance company pays up to your policy limits – not a penny more
- You become personally responsible for every dollar above those limits
The financial aftermath can be devastating. Your savings account? Your investments? Even your home? All could be at risk through a lawsuit. Courts can order wage garnishment, taking a chunk of your paycheck until the debt is satisfied. And those unpaid judgments will wreak havoc on your credit score for years.
I remember helping a client named Michael who had state minimum coverage (25/50/25) when he caused an accident involving a surgeon. The surgeon’s hand injuries required $75,000 in medical treatment, and he couldn’t work for months, losing $200,000 in income. His $85,000 luxury car was totaled.
Michael’s insurance paid just $25,000 for the injuries and $25,000 for the car – leaving him personally on the hook for $310,000. His life was turned upside down financially.
The umbrella solution is surprisingly affordable. For about the cost of a monthly dinner out ($200-400 annually), you can add a $1 million umbrella policy that kicks in when your auto liability limits are exhausted. It’s genuinely one of the best values in the insurance world, especially for anyone with assets to protect.
Liability Car Insurance Coverage in No-Fault States
Massachusetts operates under no-fault insurance laws, which creates an interesting twist in how liability car insurance coverage functions after an accident.
In Massachusetts, each person’s own insurance pays for their medical expenses through Personal Injury Protection (PIP), regardless of who caused the accident. The state requires $8,000 in PIP coverage, which handles medical bills, 75% of lost wages, and even services like help around the house while you recover.
But don’t be fooled by the term “no-fault” – it doesn’t mean fault doesn’t matter at all. Property damage claims still follow traditional fault rules, with the at-fault driver’s property damage liability covering repairs to other vehicles. And if injuries are serious enough to cross certain thresholds, victims can step outside the no-fault system and pursue claims against the at-fault driver.
This is why maintaining solid liability car insurance coverage remains essential even in no-fault states like Massachusetts. Your PIP benefits can be quickly exhausted in serious accidents, leaving you vulnerable without adequate liability protection.
For our clients in New Hampshire and Maine, which operate under traditional tort (fault-based) systems, the rules are more straightforward. The at-fault driver’s insurance pays for both bodily injury and property damage up to policy limits.
Some drivers need to file an SR-22 form (a certificate proving insurance coverage) after serious violations. If that’s you, we can help steer those requirements while ensuring you have appropriate liability car insurance coverage.

Conclusion
Liability car insurance coverage isn’t just another insurance requirement—it’s your financial safety net on the road. After all we’ve explored together in this guide, I hope you can see why this coverage matters so much for your peace of mind and financial security.
Think about what we’ve learned: liability car insurance coverage protects you when you’re responsible for an accident. It steps in to pay for the other person’s medical bills and vehicle repairs so those costs don’t come directly from your savings account or home equity.
While almost every state requires some form of liability insurance, those minimum requirements rarely provide enough protection if you cause a serious accident. Remember those three numbers (like 100/300/100)? They represent thousands of dollars in coverage—and the difference between adequate protection and potential financial disaster.
Most drivers can get basic liability coverage for around $736 per year, though your personal rate will depend on factors like your driving history, age, location, and the vehicle you drive. That’s a small price to pay for significant protection.
If you’re driving an older car with little value, liability-only coverage might make sense. But if your vehicle would be difficult to replace out-of-pocket, you should seriously consider adding comprehensive and collision coverage for more complete protection.
And for those with assets to protect, an umbrella policy provides remarkably affordable extended protection beyond your auto liability limits—often just a few hundred dollars a year for a million dollars in coverage.
“Insurance isn’t just about checking a box to drive legally,” as Geoff Stanton often reminds our clients. “It’s about protecting what you’ve worked hard to build—your home, your savings, your future.”
