The coverage you need depends on what you own, what you owe, and your state's minimum requirements
Your state sets a legal floor — usually liability coverage that pays for damage or injury you cause to someone else. But that minimum is almost never enough. If you have a car loan or lease, your lender will require collision and comprehensive coverage. If you own your car outright and have savings, you might choose lower limits to save money. The real question is whether the coverage you pick would actually cover your costs if something goes wrong.
Most people need more than the state minimum because a serious accident can cost far more than the legal requirement covers. A single injury claim can reach $100,000 or more in medical bills, lost wages, and pain-and-suffering damages. If you cause that accident, you pay the difference between what your insurance covers and what the injured person wins in court — from your own money, your paycheck, and your assets.
Key Takeaways
- Your state sets a minimum liability limit, but it typically covers only a fraction of what a serious accident actually costs.
- If you have a car loan or lease, your lender requires collision and comprehensive coverage, and you cannot opt out.
- Liability limits should match your assets and income — if you own a home or have savings, carry at least $100,000 per person and $300,000 per accident.
- Collision and comprehensive coverage make sense if your car is worth more than 10 times your deductible, or if you cannot afford to replace it.
- Uninsured and underinsured motorist coverage protects you when the other driver has little or no insurance.
Understanding your state's minimum liability requirement
Every state requires liability insurance, but the minimum amount varies. Most states use a three-number format: per-person bodily injury, per-accident bodily injury, and property damage. For example, a state might require 25/50/25, meaning $25,000 per person, $50,000 per accident, and $25,000 for property damage.
These minimums exist to ensure accident victims have some recourse, but they are often inadequate. A single hospitalization can exceed $50,000. If you cause an accident that injures two people, the $25,000 per-person limit covers only the first person's basic medical costs. The second person and any remaining bills fall to you. You can look up your state's requirement on your state insurance commissioner's website or by calling your insurer.
How much liability coverage actually protects you
Liability coverage pays for injuries and property damage you cause to others. The key word is "you cause" — it does not cover your own injuries or car damage. If you are at fault in an accident, your liability insurance pays the other driver's medical bills, vehicle repairs, and legal judgments against you, up to your policy limits.
The risk is that a judgment can exceed your limits. If you cause an accident that injures someone seriously, a court might award $150,000 in damages, but your policy only covers $50,000. You owe the remaining $100,000 out of pocket. Creditors can garnish your wages or place a lien on your home. This is why carrying limits well above the state minimum is a practical choice if you have assets to protect.
A common recommendation is to carry limits equal to your net worth, or at least $100,000 per person and $300,000 per accident if you own a home or have significant savings. If you rent and have little savings, the state minimum may be your only option, but increasing it by $10 to $20 per year is usually inexpensive and worth considering.
Collision and comprehensive coverage: when they are required and when they are optional
Collision coverage pays to repair or replace your car if you hit something or someone hits you. Comprehensive coverage pays for theft, weather, vandalism, and other non-collision damage. If you have a car loan or lease, your lender requires both — you cannot decline them. The lender owns a financial interest in the car and will not allow you to risk losing it without insurance.
If you own your car outright, both coverages are optional. The trade-off is simple: you pay a deductible (usually $500 to $1,000) when you file a claim, and the insurer pays the rest. If your car is worth $5,000 and your deductible is $1,000, a collision claim pays up to $4,000. If your car is worth $2,000, the same claim pays up to $1,000. At some point, the deductible becomes so large relative to the car's value that the coverage is not worth the premium.
A rough rule: if your car is worth less than 10 times your deductible, drop collision and comprehensive. If your car is worth $8,000 and your deductible is $1,000, keep it. If your car is worth $3,000 and your deductible is $500, you are paying premiums for coverage that will barely pay anything. Also consider whether you could afford to replace the car if it were totaled. If you could not, keep the coverage even if the math suggests dropping it.
Uninsured and underinsured motorist coverage protects you from other drivers
Uninsured motorist (UM) coverage pays for your injuries if you are hit by a driver with no insurance. Underinsured motorist (UIM) coverage pays the difference if the other driver's insurance is not enough. For example, if you are hit by an uninsured driver and your medical bills are $50,000, your UM coverage pays up to your limit. If you are hit by a driver with only $25,000 in liability coverage and your bills are $50,000, your UIM coverage pays the remaining $25,000.
These coverages are required in some states and optional in others. Even where optional, they are inexpensive — often $10 to $30 per year — and worth carrying. Roughly one in eight drivers on the road is uninsured, and many more are underinsured. If you are injured by one of them, your own coverage is your only protection.
Your UM and UIM limits should match your liability limits, or at least be high enough to cover your medical expenses and lost income if you are seriously injured. If you carry $100,000 in liability, carry $100,000 in UM and UIM as well.
Medical payments coverage and personal injury protection
Medical payments coverage (Med Pay) pays your medical bills and those of your passengers, regardless of who caused the accident. It covers hospital stays, surgery, dental work, and ambulance fees. Personal injury protection (PIP) is similar but broader — it also covers lost wages and other expenses. Some states require PIP; others offer it as optional; some do not allow it at all.
Med Pay and PIP are relatively inexpensive, usually $5 to $25 per year depending on your limits. They are worth carrying because they pay quickly and do not require proving fault. If you are injured in an accident, your own Med Pay or PIP pays your bills while liability claims are being settled. They also cover you and your passengers if you are hit by an uninsured driver, before your UM coverage kicks in.
Limits are typically $1,000 to $10,000 per person. A reasonable choice is $5,000 to $10,000 if you have dependents or a high income, or $1,000 to $5,000 if you are single with modest income.
How to choose deductibles and balance cost against risk
A higher deductible lowers your premium but means you pay more out of pocket when you file a claim. A lower deductible raises your premium but reduces your out-of-pocket cost. The right choice depends on your emergency savings and how often you expect to file a claim.
If you have $2,000 in savings and your car is worth $10,000, a $1,000 deductible is risky — a collision claim would wipe out your emergency fund. A $500 deductible costs more per month but protects your savings. If you have $10,000 in savings and a $15,000 car, a $1,000 deductible is reasonable — you can absorb the cost if needed.
Also consider your driving habits. If you drive rarely, in low-traffic areas, and have a clean record, a higher deductible may make sense because your risk of a claim is lower. If you commute in heavy traffic or have a history of accidents, a lower deductible protects you from a large out-of-pocket cost when a claim is likely.
Frequently Asked Questions
What if I cannot afford higher coverage limits?
Start with your state's minimum and increase it as your budget allows. Even raising your liability limit from 25/50/25 to 50/100/50 costs only a few dollars per month for most drivers. If you have a loan or lease, you must carry collision and comprehensive, but you can raise the deductible to lower the premium.
Do I need coverage if I rarely drive?
Yes. Even a low-speed accident can cause serious injury or property damage. Your state requires liability coverage to drive legally. If you drive only occasionally, ask your insurer about low-mileage discounts or usage-based policies that charge based on how much you actually drive.
What happens if I cause an accident and my coverage limit is too low?
You are personally liable for the difference. The injured person can sue you, win a judgment, and collect from your wages or assets. This is why carrying limits above the state minimum is important if you have anything to protect.
Should I match my liability and UM/UIM limits?
Yes, ideally. If you carry $100,000 in liability, carry $100,000 in UM and UIM. This way, you have the same level of protection whether you cause an accident or are hit by an uninsured driver. Some states allow you to carry lower UM/UIM limits, but matching them is simpler and more protective.
Can I lower my premium by dropping coverage I do not think I need?
You can drop optional coverages like collision and comprehensive if you own your car outright, but you cannot drop liability — it is required by law. Dropping UM and UIM where optional will lower your premium, but the savings are usually small and the risk is large. Before dropping any coverage, ask your insurer what the premium difference is and whether you could afford to pay out of pocket if something goes wrong.
