What’s the difference between liability and full coverage car insurance?

Liability car insurance is basic coverage that pays only for injuries and property damage you cause to others. It does not pay for damage to your own vehicle. Full coverage includes collision and comprehensive insurance, protecting both third parties and your own car.

Purchasing full coverage car insurance will cover you in more situations than liability alone, largely due to the addition of coverage for your car.

What is liability car insurance?

Liability car insurance pays for injuries and damage to others when you’re financially responsible for an accident that’s your fault.

Each state requires a minimum amount of liability insurance coverage. The most common amounts for liability insurance are 25/50/25. That means $25,000 for bodily injury liability per person, $50,000 for bodily injury liability per accident, and $25,000 for property damage per accident. However, the amounts differ by state and range as low as $10,000 and as high as $100,000.

The state minimum is often too low to cover the cost of even a moderately serious accident. A 100/300/100 policy provides $100,000 per person, $300,000 per accident, and $100,000 in property damage, compared to the most common minimum of 25/50/25.

What is full coverage car insurance?

Full coverage includes collision and comprehensive insurance, as well as all coverages required by law in your state. Collision covers impact with another vehicle or object. Comprehensive covers theft, fire, vandalism, glass breakage, and animal impact. Optional coverages, including roadside assistance, rental reimbursement, and gap insurance, are available for an additional premium. A deductibleThe deductible is the amount you pay out of pocket for a covered loss when you file a claim. the insured selects applies; the insured pays that amount before the insurer pays out on a claimAn insurance claim is a request you make to your insurance company for coverage after your car is damaged or you have an accident. You can file a claim online, by phone, or in writing..

You aren’t obligated to have full coverage unless you have a loan or a lease on your vehicle. It’s required because it protects the lender’s financial stake in the vehicle.

When should you switch to liability-only car insurance?

Consider switching to liability-only car insurance if your vehicle is more than 10 years old or the annual cost of full coverage exceeds the vehicle's actual cash value. For most drivers with paid-off vehicles, liability-only becomes the better financial choice once a car's market value falls low enough that a collision or comprehensive payout would not justify the added premium.

Newer cars and those with a high value, such as exotics or high-performance cars, should have full coverage so the owner can recoup as much money as possible in the event of an accident. However, liability-only may be the better financial choice for an older car, especially one that’s paid off. Since an older car is worth less if totaled, it’s a trade-off worth considering.

So, should you get liability or full coverage insurance? It’s a personal financial choice if you don’t have a loan.

“It is up to the insured if they can afford it and do not mind paying for full coverage for peace of mind. The majority of people will drop down to liability after the vehicle is older than 10 years to avoid paying too much in auto insurance," says Lauren McKenzie, an insurance agent for A Plus Insurance in South Carolina. There is no specific time you can or should switch to liability-only car insurance. The answer usually depends on the age of your car.

FAQs

Does liability cover my car if someone else is at fault?

Liability car insurance does not cover damage to your own vehicle in any scenario. If someone else hits you and they carry liability insurance, their policy pays for your damage. If they are uninsured or underinsured and you carry only liability coverage, you have no coverage for your vehicle.

If you are at fault in an accident and carry only liability, your insurer pays for the other driver's repairs and medical bills, but your own car repairs come out of pocket. 

If your car is totaled and you carry only liability, you receive nothing from your own insurer toward a replacement vehicle.
