Car insurance coverage types explained: liability, collision, comprehensive, PIP, uninsured motorist. Learn what each covers and which you actually need.
Car insurance combines six standard coverages: bodily injury liability, property damage liability, collision, comprehensive, personal injury protection (or medical payments), and uninsured or underinsured motorist. Nearly all states require liability. Lenders require collision and comprehensive on financed or leased cars. The rest depend on state law and your situation.
This question comes up most often at the moment of car purchase, when coverage requirements suddenly change. A buyer trading a 10-year-old paid-off car for a new financed one walks into a different insurance situation: the old policy was probably liability-only, with no collision or comprehensive on a vehicle worth $4,000, and the new financed vehicle resets the equation. The lender now requires full coverage on a car worth $40,000, and most buyers do not know what their current carrier will charge until the F&I manager asks for proof of insurance and adds the new VIN.
The terms also get used inconsistently. "Full coverage" is not a specific policy you can buy. As ValuePenguin puts it, the phrase gets used a lot but there is no single standard definition; in practice it means liability plus collision plus comprehensive. ValuePenguin's 2026 rate survey puts full coverage at $2,495 per year ($208 per month) against $908 per year ($76 per month) for state-minimum coverage, a difference of about 2.7 times (ValuePenguin, ValuePenguin). Those are quotes for one profile, a 30-year-old man with good credit driving a 2018 Honda Civic EX with $500 deductibles, gathered across all 50 states and DC, so treat them as a comparison between the two coverage levels rather than as your own price. Whether you need full coverage is partly your call and partly your lender's call, depending on how you are paying for the car.
This page covers what each of the standard coverages actually pays for, who requires each one, how full coverage differs from state-minimum coverage, and how to set coverage levels intelligently at the point of purchase. The goal is to walk into the F&I desk with the answers already made, not under time pressure with the finance manager waiting.
The six standard coverages each do a specific job. Some pay other people when you cause damage. Others pay you when something happens to your car or to you. Some are required by law, some by your lender, and some are optional. Reading them as a set is the easiest way to see which ones you actually need.
Bodily injury liability pays the medical costs, lost wages, and legal defense expenses that result from injuries you or another driver on your policy cause to other people while driving your car. It pays the other party, not you. Nearly all states require it, and it is the first number in a state-minimum format like 25/50/25 (per-person and per-accident bodily injury limits in thousands of dollars). It does not pay for your own injuries or for any damage to your own vehicle. (Insurance Information Institute)
Property damage liability pays to repair or replace other people's property when you or another driver on your policy damages it: the other car you hit, a building, a fence, a utility pole. Nearly all states require it. It is the third number in a state-minimum format like 25/50/25 (property damage limit in thousands of dollars). It does not pay for your own car. If you cause a wreck, this coverage handles the other vehicle. Yours is repaired (or not) by collision and comprehensive. (Insurance Information Institute)
Collision pays to repair or replace your own car when it is damaged in a wreck with another vehicle or a stationary object, regardless of fault. That includes potholes and rollover accidents, but excludes mechanical failure and normal wear-and-tear. Collision is optional under state law, but lenders require it on financed or leased vehicles for the life of the loan or lease. It pays up to the car's actual cash value, minus your deductible (commonly $500 or $1,000), regardless of what you originally paid for the vehicle. (Insurance Information Institute)
Comprehensive pays to repair or replace your own car when it is damaged by something other than a collision: theft, vandalism, fire, flood, hail, falling rocks or branches, or hitting an animal. It is optional under state law but required by lenders on financed or leased vehicles. Like collision, it pays up to the car's actual cash value minus your deductible. Comprehensive and collision are usually quoted as a pair because most policies treat them as the two halves of physical-damage coverage on your own car. (Insurance Information Institute)
PIP is no-fault coverage that pays medical bills, lost wages, and related expenses for you and your passengers after a car accident, regardless of who caused it. About 16 states require PIP, 12 of them true no-fault states. In the rest, it may not be sold or may be a limited optional add-on. In no-fault states, PIP pays first, before any liability claim against the at-fault driver. It is the only standard coverage that pays you for your own injuries without a fault determination. (Insurance Information Institute, Insurance Information Institute)
MedPay covers medical and funeral expenses for you, your passengers, and family members hurt in an auto accident, regardless of who is at fault. Maine is the one state whose financial-responsibility requirement also includes medical payments coverage. Where it is available, MedPay is often a low-cost optional add-on. MedPay overlaps with PIP in what it pays for, so in no-fault states with mandatory PIP it is usually redundant. In tort states without PIP, it is the simplest way to get coverage for your own injuries. (Insurance Information Institute, Insurance Information Institute)
UM/UIM pays for your medical bills and vehicle damage when the at-fault driver has no insurance (UM) or not enough insurance to cover your costs (UIM). About 20 jurisdictions require uninsured motorist coverage, and only a handful require underinsured motorist coverage. In the rest both are optional, but recommended because uninsured drivers remain common. Without UM/UIM, an uninsured at-fault driver can leave you holding your own medical and repair bills with no realistic recourse beyond a personal lawsuit, which is often a dead end because the driver likely has no assets to satisfy a judgment. (Insurance Information Institute, Insurance Information Institute)
Coverage decisions hit the buyer twice during a car purchase. The first time is at the F&I desk, where three things need to be true before delivery: there is an active policy on the new vehicle, the policy meets the lender's coverage requirements (full coverage on any financed or leased car), and any optional dealer products being added to the deal (GAP, vehicle service contracts, tire and wheel) are decided separately from the insurance itself. The F&I manager's job is to confirm coverage is in place and add the new VIN to the policy. Setting coverage levels is the buyer's call, and the buyer's insurer's, not the dealership's.
The pressure point is timing and default behavior. Most buyers under F&I time pressure default to whatever their current carrier quotes for the new vehicle, often without checking what their old policy's coverages and limits actually were. A buyer trading a 10-year-old paid-off car for a new financed SUV experiences a real change. Liability-only coverage with no collision or comprehensive on the old car gives way to lender-required full coverage on the new one. Collision and comprehensive premiums on a $40,000 vehicle look nothing like premiums on a $4,000 vehicle, and that math surprises a lot of buyers in the F&I office.
A prepared buyer arrives knowing which coverages they currently carry, knowing what the lender will require (collision and comprehensive plus state-minimum liability), and understanding that coverage-level decisions are made by the buyer and the insurer, not by the F&I manager. Coverage decisions made under time pressure tend to default to the same limits as the old policy, which is usually the wrong call for a new financed vehicle. Industry guidance from the Insurance Information Institute is to carry more than state minimum liability so a serious at-fault accident does not blow through the limits and expose personal assets (Insurance Information Institute).
One specific risk the F&I desk does not solve is the lapsed-coverage scenario. The CFPB notes that if insurance lapses on a financed vehicle, the lender can buy force-placed insurance and charge the borrower for it. That policy protects only the lender, not the borrower, and is usually a lot more expensive than what the borrower could buy directly (Consumer Financial Protection Bureau). Even a one-day gap during the purchase transition invites this. About 1 in 5 buyers arrive at the dealership without active insurance coverage, which makes the gap a real risk for a meaningful share of car deals (2026 Embedded Auto Insurance Study, Polly, n=1,055).
Two different questions get lumped together as "minimum versus full," and they are not the same decision. One is how high your liability limits go. The other is whether you buy physical damage coverage at all. Both are about how much risk you keep rather than hand to the insurer, and the cost gap between the cheapest and the fullest version of a policy is the largest lever on this page. ValuePenguin's 2026 rate survey puts state-minimum coverage at $908 per year ($76 per month) and full coverage at $2,495 per year ($208 per month), a difference of about $1,587 per year or $132 per month (ValuePenguin). For a financed or leased car, that decision is already made: the lender requires full coverage. For a paid-off car, the decision is yours, and two specific moves are worth running the math on.
The first move is whether to keep collision and comprehensive on an older paid-off vehicle. Consumer Reports gives a ratio check: consider dropping them when your annual premiums equal or exceed 10 percent of your car's book value, or the vehicle is more than 10 years old (Consumer Reports). ValuePenguin reaches the same 10-year threshold from the other direction, finding that by then full-coverage costs have climbed to about 35% of the car's value (ValuePenguin). At that point, dropping collision and comprehensive becomes defensible for owners who could afford to replace the car themselves. The second move is liability limits. State minimums (often around 25/50/25, meaning $25,000 per person, $50,000 per accident, $25,000 property damage) can be exceeded by a single serious at-fault accident in minutes. The Insurance Information Institute recommends carrying enough liability to protect assets like a home or savings, which usually means going above the state-required floor (Insurance Information Institute).
Polly's data adds context to what buyers actually pay. The median monthly quote through Polly's marketplace fell to $157 in Q2 2026, down from $168 in Q1 2026, meaningfully below the national average (Polly Quarterly Embedded Insurance Report, Q2 2026). Deductibles and coverage levels are the two largest levers a buyer can pull at the point of purchase. Raising the deductible lowers monthly premium but increases what you pay out of pocket in a claim. Dropping a coverage lowers premium more, and more of the risk stays with you. Neither choice is universally right; both should be made deliberately, not by accident under F&I time pressure.
State law shapes which coverages are mandatory in four meaningful ways. Liability coverage is required in nearly every state and Washington, D.C. New Hampshire is the only state where it is not strictly mandatory, though drivers there must still demonstrate financial responsibility after an accident. Liability minimums are written as ratios like 25/50/25 (per-person bodily injury, per-accident bodily injury, and property damage limits in thousands of dollars) and vary state to state. Verify your state's specific minimum before assuming the floor. (Insurance Information Institute)
About 16 states require personal injury protection (PIP) on every policy. Twelve of those are true no-fault states, where PIP pays first, before any liability claim against the at-fault driver. About 20 jurisdictions require uninsured motorist coverage and only a handful require underinsured motorist coverage; in the rest both are optional but recommended because uninsured drivers remain common nationally. Maine is the one state whose financial-responsibility requirement also includes medical payments (MedPay). When you are comparing quotes, the legal floor for a comparable policy depends on these state-specific requirements; quotes that drop a required coverage are not real comparisons. (Insurance Information Institute, Insurance Information Institute)
Polly's embedded marketplace lets car buyers compare quotes from 40+ national carriers at the dealership, side by side at identical coverage levels. The same parameters (liability limits, deductibles, optional add-ons like UM/UIM or MedPay) are held constant across every quote, so the price difference you see is real and not a function of different coverages. For a financed vehicle, that means comparing full-coverage quotes against full-coverage quotes, not minimum against full. Sixty-eight percent of buyers who compared a quote through Polly at the dealership found savings (Polly transaction data, Q3 2025, n=8,606).
Setting coverages intelligently matters more on a new car than most buyers realize. The F&I desk is not where coverage decisions should get made under time pressure. Walking in with your coverages already chosen (liability above state minimum to protect assets, full coverage already factored into your budget, UM/UIM included even if your state does not require it) turns the F&I conversation into a verification step rather than a scramble. Polly's platform handles the comparison in 15 to 30 minutes at the dealership; buyers who prefer to compare from home can use polly.co before they visit.
Polly distributes personal lines insurance only: auto, home, and renters. Polly does not sell GAP, vehicle service contracts, or any F&I add-on products. The CTA on this page is for personal lines coverage comparison, making sure the underlying auto policy on your new car carries the right coverages at competitive rates.
Car insurance combines six standard coverages: bodily injury liability, property damage liability, collision, comprehensive, personal injury protection (or medical payments), and uninsured or underinsured motorist. Nearly all states require liability. Lenders require collision and comprehensive on financed or leased cars. The rest depend on state law and your situation.
Liability pays only for damage you cause to other people or their property and is the legal minimum in nearly every state. Full coverage is liability plus collision and comprehensive, which pay for damage to your own car. Full coverage costs about 2.7 times more on average.
Most state minimums are around 25/50/25 ($25,000 per person, $50,000 per accident, $25,000 property damage). The Insurance Information Institute recommends going well above the minimum to protect assets like a home or savings, since a serious at-fault accident can exceed minimum limits quickly.
Lenders require collision and comprehensive for the life of the loan, on top of your state's liability minimum. If coverage lapses, the lender can buy force-placed insurance and bill you. Force-placed insurance is typically far more expensive than a self-purchased policy and covers only the lender.
Consumer Reports suggests dropping them when your annual premiums equal or exceed 10 percent of the car's book value, or the vehicle is more than 10 years old. It makes sense when you own the car outright and could afford to replace it.
It pays your costs when an at-fault driver has no insurance or not enough. About 20 jurisdictions require it; in the rest it is optional. Uninsured drivers remain common nationally, and UM/UIM is the only coverage that pays for your injuries and vehicle damage in those collisions.
PIP is no-fault coverage that pays medical bills, lost wages, and related expenses for you and your passengers after an accident, regardless of who caused it. About 16 states require PIP, 12 of them no-fault. In the remaining states it may be unavailable or sold as an optional add-on.
