What basic auto insurance actually includes
Basic auto insurance is the legal minimum required to drive in every state, but what that minimum covers varies by location. In most states, basic coverage means liability insurance — which pays for damage or injuries you cause to someone else — and nothing that protects your own vehicle. A few states allow you to post a bond or self-insure instead, but liability is the constant requirement.
The specific dollar limits you must carry depend on your state. Some states set minimums as low as $15,000 per person for bodily injury and $30,000 per accident; others require $50,000 and $100,000. Your state's Department of Motor Vehicles or insurance commissioner's office publishes the exact minimums that explore where you live. Carrying only the state minimum is legal but leaves you exposed if you cause a serious accident — a single crash can easily exceed those limits.
Key Takeaways
- Basic liability insurance is the legal minimum in every state, but the dollar amounts required vary by state and are set by law, not by insurers.
- Liability covers damage you cause to other people and their property, not damage to your own vehicle.
- Collision and comprehensive coverage are optional add-ons that protect your own car, and lenders require them if you have a loan or lease.
- Uninsured motorist coverage is optional in most states but protects you if someone without insurance hits you.
- The state minimum is legal but often leaves you underinsured — most financial advisors recommend carrying higher limits.
Liability coverage: what it pays for and what it doesn't
Liability insurance has two parts: bodily injury liability and property damage liability. Bodily injury liability pays medical bills, lost wages, and pain-and-suffering claims if you injure or kill someone in an accident you caused. Property damage liability pays to repair or replace the other person's vehicle, fence, building, or other property. Both are written as limits per person and per accident — for example, 25/50/25 means $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage.
What liability does not cover: your own medical bills, your own vehicle damage, lost wages from your own injuries, or damage to your own property. It also does not cover legal fees if you are sued, though some policies include a small amount of legal defense coverage. If you cause an accident and the other person's damages exceed your liability limits, they can sue you personally for the difference — which is why carrying limits well above the state minimum is important if you own assets.
Optional coverage that protects your own vehicle
Collision coverage pays to repair or replace your car if you hit another vehicle, object, or animal, or if your car rolls over. Comprehensive coverage pays for damage from theft, weather, vandalism, or hitting an animal on the road. Both come with a deductible — typically $500 or $1,000 — that you pay out of pocket before insurance covers the rest.
If you own your car outright, collision and comprehensive are optional. If you have a loan or lease, your lender or leasing company requires both. The cost of adding these coverages depends on your car's age and value, your driving history, and your location. On an older car, the monthly premium for collision and comprehensive might exceed what the coverage would actually pay out, which is why many people drop these coverages once their car is paid off.
Uninsured and underinsured motorist coverage
Uninsured motorist coverage (UM) pays your medical bills and lost wages if someone without insurance hits you. Underinsured motorist coverage (UIM) covers you if the at-fault driver's liability limits are too low to pay your full damages. In some states, UM and UIM are optional; in others, they are required unless you sign a form declining them. The cost is usually low — often $10 to $30 per month — because claims are less common than collision claims.
UM and UIM protect you and your passengers, not the other driver. They do not cover damage to your vehicle — that is what collision coverage does. If you live in an area with high rates of uninsured driving, or if you carry high liability limits and want protection that matches them, these coverages are worth the cost. Many people skip them to save money, which is a gamble that depends on your local traffic patterns and your financial cushion if you are injured.
Medical payments coverage and personal injury protection
Medical payments coverage (MedPay) pays reasonable medical expenses for you and your passengers after an accident, regardless of who caused it. It covers ambulance rides, emergency room visits, surgery, and follow-up care. The limit is usually $1,000 to $5,000 per person. Personal injury protection (PIP) is similar but broader — it also covers lost wages and childcare costs if you are injured and unable to work.
MedPay is optional in most states and costs $10 to $25 per month for modest limits. PIP is required in no-fault states (Florida, Michigan, New York, and a few others) and optional elsewhere. Both are secondary to your health insurance, meaning your health plan pays first and these coverages fill in gaps. If you have good health insurance with low deductibles, MedPay and PIP are less valuable. If you are uninsured or underinsured medically, they provide a safety net.
How state minimums compare and why they matter
State minimum liability limits range widely. California requires 15/30/5 (meaning $15,000 per person, $30,000 per accident for bodily injury, and $5,000 for property damage). New York requires 25/50/25. Texas requires 30/60/25. These minimums are the floor, not a recommendation. A single serious accident — a crash that injures multiple people or causes significant property damage — can easily generate claims exceeding the state minimum by tens of thousands of dollars.
Insurance companies and financial advisors typically recommend carrying limits of at least 100/300/100 or higher, especially if you own a home or have savings. The cost difference between the state minimum and these higher limits is usually $20 to $50 per month. If you cause a major accident and your liability limits are too low, the injured party can sue you for the difference, potentially garnishing your wages or placing a lien on your home. Checking your state's specific minimums and comparing them to what you actually carry takes 10 minutes and can prevent a financial disaster.
Frequently Asked Questions
Does basic insurance cover damage to my own car?
No. Basic liability insurance covers damage you cause to someone else's vehicle or property. To cover damage to your own car, you need collision coverage (for crashes) or comprehensive coverage (for theft, weather, or vandalism). If you have a loan or lease, your lender requires both.
What happens if I cause an accident and my liability limits are too low?
The injured party can sue you personally for the difference between your insurance payout and their actual damages. If they win, they can garnish your wages or place a lien on your home. This is why carrying limits well above the state minimum is important if you own assets.
Is uninsured motorist coverage worth the cost?
It depends on your area and your financial situation. If you live where many drivers are uninsured, or if you could not afford a major medical bill out of pocket, it is worth the $10 to $30 per month. If you have strong health insurance and a financial cushion, it is less critical.
Can I drop collision and comprehensive once my car is paid off?
Yes, you can drop them anytime once you own the car outright. However, if you still owe money on a loan or lease, your lender requires both. On older cars, the monthly premium for these coverages might exceed what the insurance would actually pay out, which is when many people choose to drop them.
What is the difference between MedPay and PIP?
Medical payments coverage pays medical expenses only. Personal injury protection (PIP) also covers lost wages and childcare costs if you are injured and unable to work. PIP is required in no-fault states; MedPay is optional in most places and costs less.
