Liability vs. full coverage car insurance

The most common question related to car insurance is, "how much coverage do I need?" Whether or not you need full coverage or liability largely depends on how you own your vehicle, the value of your vehicle, your desired coverage level. If your car is leased, the dealership or bank — the actual owner of the vehicle — typically will dictate minimum insurance requirements. If you own your vehicle outright, you'll have more flexibility in carrying the state minimum coverage or opting for additional coverage, like collision and comprehensive. Generally, if your vehicle is worth more than $4,000, you should add comprehensive and collision to your insurance policy.

If your vehicle is worth less than $4,000, you should consider removing your full coverage. As you can see with our data below, full coverage can increase your premium by 103% or $370!

What is covered by minimum liability and full-coverage auto insurance policies?

Because car insurance laws are written and enforced at the state level, your state minimum liability coverage will vary based on your location. Most U.S. states mandate the following:


State-minimum auto insurance coverage:

  • Bodily injury liability: Covers medical bills resulting from an accident caused by you or someone on your car insurance policy.
  • Property damage liability: Covers physical damage to another person’s vehicle or property after an at-fault accident.
  • Uninsured or underinsured motorist coverage: Covers instances in which the at-fault party does not carry insurance or does not carry enough coverage to repay damages. These insurance options include bodily injury and property damage coverage. Uninsured and underinsured motorist coverage requirements vary by state.
  • Medical payments: Covers your medical bills, regardless of who is at fault. Medical payment coverage is required in some — not all — states.
  • Personal injury protection (PIP): Covers medical expenses for you and your passengers — regardless of fault — up to the coverage limit. PIP insurance is only required in no-fault car insurance states.


Each state mandates specific, required coverage levels for each of the above insurance types. You'll need to meet or exceed your state's minimum coverage levels to drive legally.


Full coverage car insurance:

While state minimum auto insurance is straightforward, “full coverage” is a bit of a misnomer. “Full coverage” isn’t really a technical or accurate way to describe a car insurance policy — it usually denotes comprehensive and collision insurance, but can also comprise rental reimbursement and roadside assistance coverage.


One major difference between state minimum and full coverages concerns who is covered. State minimum auto insurance generally includes liability coverage only, i.e., damage you cause to others. Full coverage insures both you and your vehicle. So when do you need full coverage, and when will liability-only car insurance suffice?




Full coverage car insurance or liability insurance — which is better?

Generally, full coverage offers much more in terms of coverage. However, it will greately increase your premium. So, if you don't need comprehensive coverage, it is not better for you. Let's explore this further.

Leased and financed vehicles: full coverage required

You will be required to carry “full coverage” car insurance if you’re financing your vehicle. Since another entity — usually a bank or auto dealership — maintains an interest in the vehicle, they get to decide how the car is insured. Auto leasing and financing companies generally require collision and comprehensive coverage with low deductibles.

If you lease your car, you don't own the vehicle outright and you will be required to carry additional coverage to protect the asset. This often includes collision, comprehensive, and gap insurance.


Owned vehicle: full coverage optional

If you own your vehicle, you have complete control over your insurance. If you’re unsure of what coverage to select, consider your vehicle's value. Use an estimator like the Kelley Blue Book to assess the value of your vehicle and determine how much coverage you need.

If your vehicle is worth more than $4,000, collision and comprehensive coverage are recommended. Without these coverages, you would not receive compensation if your vehicle was severely damaged or totaled.




How much do full coverage car insurance and state minimum auto insurance cost?

Below is a break down of average premiums by coverage level. If you opt to boost your coverage from the minimum amount to add comprehensive and collision, expect to pay over double what you were paying for just the state-required minimum amount of liability. This disparity in pricing is less apparent if you already carry comp and collision coverage. Whether you have a $500 or $1000 deductible, the difference in premium between coverage levels maxes out at about 29%.
