What is liability car insurance?
Liability car insurance covers injuries and property damage you cause others in an accident, including passengers in your car.[1] Like most states, Arizona requires drivers to have minimum liability coverage, which ensures you can pay for medical bills and repair costs after an accident.
Liability insurance is usually more affordable than full coverage. But liability insurance doesn’t cover your injuries or vehicle damage, and can leave you exposed to financial loss following an at-fault accident. Drivers looking for the best car insurance in Arizona may want to purchase full-coverage insurance for better financial protection.

Minimum liability car insurance requirements in Arizona
Arizona state law requires drivers to carry a minimum amount of liability car insurance. Liability coverage helps pay for injuries and damage you cause to others in an accident.
You need to have at least $25,000 per person and $50,000 per accident of bodily injury liability coverage in Arizona. You also must have at least $15,000 of property damage liability coverage.
But liability-only insurance won’t pay to repair or replace your vehicle after an at-fault accident. Consider full-coverage car insurance for more financial protection, especially if you finance your car or have an auto lease.
The table below lists the coverage you need to legally drive in Arizona.
Coverage Type | Minimum Requirement in Arizona |
|---|---|
| Bodily liability insurance | $25,000 per person / $50,000 per accident |
| Property damage liability insurance | $15,000 in property damage |
Is minimum liability coverage enough in Arizona?
Minimum liability insurance may not be enough coverage for all situations in Arizona. Insurance professionals typically recommend Arizona drivers carry 100/300/100 limits of liability coverage for greater financial protection from at-fault accidents.
If you cause a car accident in Arizona, liability coverage pays only for injuries and damages to other people, vehicles, and property. Unlike full coverage, it won’t pay for your vehicle’s repairs if you caused the accident, or protect it from theft, vandalism, or weather damage.
These are some situations when you may want to consider additional coverage in Arizona:
You finance your vehicle. If you lease or finance your car, lenders usually require you to have full coverage to protect their investment.
You drive a new vehicle. Newer cars cost more to repair than older models. Adding collision and comprehensive coverage can help if you hit an object or if someone steals your car.
You want to cover medical costs. Medical payments coverage (MedPay) covers medical bills, rehabilitation services, or funeral expenses for you and your passengers after an accident, regardless of fault.
You want protection from uninsured/underinsured drivers. Uninsured/underinsured motorist coverage helps pay for injuries and damages if a driver with either no coverage or insufficient coverage hits you. It also covers losses from hit-and-runs.
Penalties for driving without liability insurance in Arizona
Driving without liability insurance in Arizona can have steep penalties. You could face fines and suspension of your driver’s license, registration, and plates. You will also have to file an SR-22 certificate of financial responsibility.[2]
Here’s how the penalties break down if you’re caught driving without liability insurance in Arizona.
Offense | License and Registration Suspension | Fine | Other Penalties |
|---|---|---|---|
| First offense | Three months | $500 | SR-22 certificate requirement |
| Second offense | Six months | $750 | SR-22 certificate requirement |
| Third offense | 12 months | $1,000 | SR-22 certificate requirement |

How to find cheap liability car insurance in Arizona
Arizona liability car insurance rates are already slightly lower than the national average. Below are some strategies to help you find even cheaper rates in Arizona:
Ask about discounts. Auto insurance discounts can help lower your rates. Ask your insurer which discounts you may qualify for, like safe driver, good student, pay-in-full, and multi-vehicle discounts.
Consider bundling. Combining your Arizona car insurance with homeowners or renters insurance from the same company can lower your premiums on both policies.
Switch to usage-based coverage. Drivers with a clean record or who don’t drive often may save by switching to a telematics program or pay-per-mile coverage. Pay-per-mile insurance might be a good option for Arizona drivers with a DUI and teens.
Shop around for the best rate. Compare rates from at least three insurers to find the best rates in Arizona. Check Arizona auto insurance quotes every six months to make sure you’re still getting the lowest rate.[3]
