Key takeaways
- Liability insurance pays for damage and injuries you cause to others; it does not pay to fix your own car.
- Full coverage usually means liability plus collision and comprehensive, which cover damage to your vehicle.
- Lenders and leasing companies almost always require full coverage until the car is paid off.
- Dropping to liability only can make sense for an older, low-value car if you could afford to replace it.
In this guide
Liability insurance pays for injuries and property damage you cause to other people, while full coverage adds collision and comprehensive, which pay to repair or replace your own car. Liability-only is cheaper and meets state requirements, but full coverage is usually required on a financed or leased car and protects vehicles you could not easily replace.
The choice comes down to three questions: is the car financed, what is it worth, and could you absorb its loss? This guide explains each option and how to decide.
What liability insurance covers
Liability coverage is the core of every auto policy and is required in nearly every state. It has two main parts:
- Bodily injury liability pays for medical bills, lost wages and legal costs for people you injure in an at-fault accident.
- Property damage liability pays for damage you cause to other people's cars, fences, buildings and other property.
Liability does not pay to fix your own car or treat your own injuries. Limits are usually written as three numbers, such as 50/100/50, meaning $50,000 bodily injury per person, $100,000 per accident and $50,000 for property damage.
State minimum limits are often low compared with the cost of a serious crash. If damages exceed your limits, you can be personally responsible for the rest.
What full coverage car insurance includes
"Full coverage" is not an official policy type, but it generally means:
- Liability (required by your state)
- Collision, which pays to repair or replace your car after a crash with another vehicle or object, regardless of fault
- Comprehensive, which covers theft, vandalism, fire, hail, flooding, falling objects and animal strikes
Many full coverage policies also include uninsured/underinsured motorist coverage and, in some states, personal injury protection or medical payments. Collision and comprehensive come with a deductible, the amount you pay before insurance kicks in. For a fuller breakdown of each piece, see our guide to types of car insurance coverage.
Liability vs. full coverage at a glance
| Liability only | Full coverage | |
|---|---|---|
| Pays for others' injuries and property | Yes | Yes |
| Pays to fix your car after an at-fault crash | No | Yes (collision, minus deductible) |
| Covers theft, hail, fire, vandalism | No | Yes (comprehensive, minus deductible) |
| Meets state legal requirements | Yes, if limits meet minimums | Yes |
| Accepted by lenders and leasing companies | Generally no | Yes |
| Relative cost | Lower | Higher, often much higher |
Full coverage commonly costs well over double what a minimum liability policy costs, but the gap depends on your car, deductibles and location. Our guide on how much car insurance costs explains the pricing factors.
When full coverage makes sense
Full coverage is usually the better choice if:
- Your car is financed or leased. Lenders require collision and comprehensive to protect their collateral, and dropping them can lead to force-placed insurance, which is typically expensive.
- Your car is newer or valuable. A total loss would be a large financial hit.
- You could not replace the car from savings. If losing the car would leave you without transportation, the premium buys real protection.
- You live where theft or weather claims are common. Comprehensive is often relatively inexpensive compared with the risk it covers.
When liability-only may be enough
Switching to liability-only can be reasonable when:
- The car is paid off and older, with a modest market value.
- The annual cost of collision and comprehensive is high relative to what the insurer would pay out after deductibles.
- You have enough savings to repair or replace the car without hardship.
A common rule of thumb says to reconsider physical damage coverage when its annual cost reaches about 10% of the car's value. It is a guideline, not a law; your savings and reliance on the car matter more.
A middle-ground option
You do not have to choose all or nothing. Some drivers keep comprehensive, which is often relatively cheap, while dropping collision. Others raise their deductibles to $1,000 or more to lower the cost of physical damage coverage while keeping protection against a major loss.
How much liability coverage should you carry?
Whether you choose liability-only or full coverage, your liability limits deserve attention. They protect your savings, home equity and future wages if you cause a serious crash, and they are the part of the policy that covers the largest potential losses.
State minimums are designed to set a legal floor, not to fully protect most households. Many drivers choose limits such as 100/300/100 or higher, and people with significant assets sometimes add an umbrella policy on top. Raising liability limits often costs less than drivers expect, because the price of each additional layer of coverage tends to shrink as limits rise. Ask for quotes at a few different limit levels to see the actual difference.
How to decide in four steps
- Check your loan or lease terms. If full coverage is required, the decision is made.
- Look up your car's current value using a vehicle pricing guide.
- Get the price of collision and comprehensive separately from your insurer or agent.
- Compare against your emergency fund. If losing the car would be a hardship, keep the coverage.
Revisit the decision every year or two, since cars lose value and your finances change. A good moment to review is when you pay off a car loan, when your emergency fund grows or shrinks, or when your renewal notice shows a price jump.
The bottom line
Liability insurance protects other people and your finances from lawsuits; full coverage also protects your own car. Keep full coverage if the car is financed, valuable or hard to replace. Once the car is paid off and its value is low, liability-only with strong limits can be a sensible way to save.
Frequently asked questions
Is full coverage the same as being fully covered?
No. Full coverage is an informal term, not an official policy type. It usually means liability plus collision and comprehensive, but it does not cover everything. Mechanical breakdowns, normal wear, custom parts beyond policy limits and some rental or towing costs may not be covered. Always check your declarations page to see exactly which coverages and limits you have.
Does liability insurance cover my car if someone hits me?
Your own liability coverage does not pay for your car. If another driver is at fault, their liability insurance should pay for your repairs. If that driver is uninsured or underinsured, you would need uninsured motorist property damage coverage (where available) or collision coverage on your own policy to pay for the damage, minus any deductible.
When should I drop full coverage?
Consider dropping collision and comprehensive once your car is paid off and its value has fallen to the point where the premium and deductible no longer make sense. A common guideline is when those coverages cost around 10% or more of the car's value per year. Only drop them if you could afford to repair or replace the car yourself.
Is liability-only insurance enough for an old car?
It can be, as long as your liability limits are high enough to protect your finances. Liability-only removes coverage for your own car, not for the harm you might cause others. Many drivers who switch to liability-only on an older car keep, or even raise, their liability limits and uninsured motorist coverage, since those protect against the largest financial risks.
