The coverage amounts you need depend on your state's minimum requirements, your assets, and your risk

Every state sets a legal minimum for liability coverage — the insurance that pays for damage or injury you cause to someone else. That minimum is usually low: often $25,000 per person for injury, $50,000 per accident for injury, and $25,000 for property damage. But the minimum is not the same as the right amount for you. If you own a home, have savings, or drive frequently, carrying only the minimum leaves you exposed to a lawsuit that could take those assets.

The coverage you buy breaks into two categories: liability (what you owe if you cause an accident) and physical damage (what your own insurance pays if your car is damaged). How much of each you need is a personal decision based on what you have to lose and what you can afford to replace.

Key Takeaways

  • Your state sets a legal minimum for liability coverage, but that minimum often does not protect your home or savings if you cause a serious accident.
  • Most insurance agents recommend liability limits of at least $100,000 per person and $300,000 per accident if you own property or have significant assets.
  • Collision and comprehensive coverage are optional but required by lenders if you have a car loan or lease.
  • Your deductible — the amount you pay out of pocket before insurance kicks in — directly affects your monthly premium; higher deductibles lower your cost but raise your risk.
  • Uninsured and underinsured motorist coverage protects you if someone else causes an accident and has no insurance or insufficient coverage.

Liability coverage: what protects your assets

Liability coverage has two parts: bodily injury liability and property damage liability. Bodily injury pays for medical bills, lost wages, and pain-and-suffering claims if you injure or kill someone. Property damage pays if you damage someone else's car, house, fence, or other property.

Your state's minimum is a floor, not a recommendation. If you cause an accident that injures multiple people or damages an expensive vehicle, the medical bills and repair costs can easily exceed your state's minimum. A jury judgment or settlement can then go after your wages, bank accounts, and home equity. Carrying limits of $100,000 per person and $300,000 per accident is common among people with assets to protect. Some insurers offer $250,000 or $500,000 limits at a modest increase in premium.

If you have very little in savings or assets, your state's minimum may be sufficient — though even then, a serious injury claim can follow you for years through wage garnishment. If you own a home or have retirement savings, higher limits are worth the cost.

Collision and comprehensive: protecting your own car

Collision coverage pays to repair or replace your car if you hit another vehicle, object, or person. Comprehensive covers damage from weather, theft, vandalism, and animal strikes — anything except a collision. Both are optional if you own your car outright, but required if you have a loan or lease.

The trade-off is your deductible. A $500 deductible means you pay $500 out of pocket; insurance pays the rest. A $1,000 deductible lowers your monthly premium but means you absorb more cost if you have a claim. If your car is worth $5,000 or less, a high deductible ($1,000 or more) may make sense because the insurance payout would be modest anyway. If your car is worth $15,000 or more, a lower deductible ($250 or $500) protects you better against a total loss.

If your car is old and worth very little, dropping collision and comprehensive entirely saves money — you would simply replace the car if it were damaged. But if you still owe money on it, your lender will not allow that.

Uninsured and underinsured motorist coverage

Uninsured motorist (UM) coverage pays your medical bills and lost wages if someone without insurance hits you. Underinsured motorist (UIM) coverage kicks in when the other driver's insurance is not enough to cover your damages. In many states, this coverage is optional; in others, it is required unless you decline it in writing.

UM and UIM are inexpensive add-ons — often $10 to $30 per month — and they protect you against a real risk: roughly one in eight drivers on the road is uninsured. If an uninsured driver causes an accident that injures you or damages your car, your own UM coverage pays instead of relying on the other driver's insurance (which does not exist). Many people set UM limits equal to their liability limits so the protection is consistent.

Medical payments and personal injury protection

Medical payments coverage (Med Pay) pays your medical bills and your passengers' bills after an accident, regardless of who caused it. It covers hospital visits, surgery, dental work, and ambulance fees. Personal injury protection (PIP) is similar but also covers lost wages and other expenses; it is required in some states and optional in others.

These coverages are relatively cheap — $5 to $15 per month for Med Pay — and useful if you do not have health insurance or if your health insurance has a high deductible. They pay quickly and do not require proving fault, so you can get treatment without waiting for a liability claim to settle.

How your age, driving record, and car affect the amount you need

A young driver or someone with accidents on their record is statistically more likely to cause an accident, which argues for higher liability limits to protect against a large judgment. A driver with a clean record and decades of experience has lower risk, though this does not eliminate it.

The value and type of your car also matters. A new luxury car is expensive to repair, so collision and comprehensive coverage is important if you have a loan. An older sedan worth $8,000 may not justify the cost of collision coverage if your deductible is high. A car you drive 50 miles per week has less exposure than one you drive 500 miles per week.

Your financial situation is the biggest factor. If you have a mortgage, retirement accounts, or significant savings, higher liability limits are worth the cost because a lawsuit could take those assets. If you have minimal assets and no dependents, your state's minimum may be enough, though it is still a risk.

Bundling and discounts that lower your total cost

Most insurers offer discounts if you bundle car insurance with home or renters insurance — typically 10 to 25 percent off your car premium. You may also get discounts for a clean driving record, completing a defensive driving course, paying your premium in full rather than monthly, or installing anti-theft devices. Some insurers offer usage-based programs that monitor your driving and reward safe habits with lower rates.

These discounts can make higher coverage limits more affordable. A $15-per-month discount from bundling could cover the cost of raising your liability limits from your state's minimum to $100,000 per person. Ask your insurer what discounts you may have access to for before you finalize your coverage.

Frequently Asked Questions

What happens if I cause an accident and my liability limit is too low?

The injured person can sue you for the difference between your insurance payout and their actual damages. If they win, the court can garnish your wages, seize your bank accounts, and place a lien on your home. This can continue for years. That is why carrying limits higher than your state's minimum protects your assets.

Should I raise my deductible to lower my monthly premium?

Raising your deductible from $500 to $1,000 typically saves $10 to $30 per month. But if you have an accident, you pay $1,000 out of pocket instead of $500. This trade-off makes sense if you have an emergency fund and drive safely; it is riskier if you live paycheck to paycheck or have a history of accidents.

Do I need collision coverage if my car is paid off?

No — collision is optional once you own your car outright. But if you could not afford to replace your car if it were totaled, collision coverage is worth keeping. If your car is worth less than your annual collision premium multiplied by five, dropping it may save money.

Is uninsured motorist coverage really necessary?

About one in eight drivers is uninsured, so the risk is real. UM coverage is inexpensive and pays your medical bills and lost wages if an uninsured driver hits you. If you have health insurance and an emergency fund, it is less critical; if you do not, it is a valuable safety net.

Can I change my coverage limits after I buy a policy?

Yes. You can contact your insurer or agent anytime to raise or lower your limits. Changes usually take effect immediately or within a few days. Raising limits mid-policy may result in a small additional charge; lowering them typically reduces your remaining premium.
