Arizona's minimum car insurance requirements and what they cost
Arizona requires every driver to carry liability insurance with minimum limits of 15/30/10: $15,000 per person for bodily injury, $30,000 per accident for bodily injury to all parties, and $10,000 for property damage. These are among the lowest minimums in the country. You must show proof of insurance when you register your vehicle and carry it with you while driving.
The cost of meeting these minimums varies by driver, vehicle, and insurer. A 35-year-old with a clean driving record typically pays $800 to $1,200 per year for basic liability in Arizona, though rates climb significantly for drivers under 25 or with accidents and violations on their record. Drivers with DUI convictions face substantially higher premiums and may be required to file an SR-22 form with the Arizona Department of Transportation.
Arizona does not require collision or comprehensive coverage, even if you have a loan or lease on your vehicle. However, lenders and lease companies almost always require both as a condition of financing. If you own your car outright, you can legally carry liability only, but that leaves you responsible for repairs if you cause an accident or your vehicle is damaged by theft, weather, or vandalism.
Key Takeaways
- Arizona's minimum liability limits are 15/30/10, meaning $15,000 per person and $30,000 per accident for injuries, plus $10,000 for property damage.
- You must carry proof of insurance at all times and show it when registering your vehicle with the Arizona Department of Transportation.
- Drivers with DUI convictions must file an SR-22 form and typically pay two to three times the standard rate for the same coverage.
- Collision and comprehensive coverage are optional if you own your car outright, but lenders and lease companies require both as part of financing.
- Arizona allows you to satisfy the insurance requirement through a self-insurance certificate if you own 25 or more vehicles, though this is rare for individual drivers.
How Arizona's uninsured and underinsured motorist coverage works
Arizona requires insurers to offer uninsured motorist (UM) coverage and underinsured motorist (UIM) coverage, though you can decline them in writing. UM coverage pays for your medical bills and lost wages if an uninsured driver hits you. UIM coverage does the same when the at-fault driver's liability limits are too low to cover your damages. Both are separate from the other driver's liability insurance and come from your own policy.
The default limits for UM and UIM coverage in Arizona are 15/30/10 — the same as the state minimum for liability. You can purchase higher limits if you want more protection. These coverages are relatively inexpensive compared to liability or collision, often adding $50 to $150 per year to your premium depending on the limits you choose.
If you decline UM or UIM coverage, your insurer must get your written consent on a form that clearly explains what you are giving up. Many drivers decline because they assume they will never be hit by an uninsured driver, but the National Highway Traffic Safety Administration estimates roughly one in eight drivers on the road is uninsured at any given time. Arizona's high number of uninsured drivers makes UM coverage particularly worth keeping.
Discounts and rate factors that affect your Arizona car insurance premium
Arizona insurers use similar rating factors across the state, but each company weights them differently. Your age, driving record, and the type of vehicle you drive are the three largest factors in your rate. A driver under 25 with an accident on their record will pay roughly three times what a 40-year-old with a clean history pays for the same coverage. Gender also affects rates — young male drivers typically pay more than young female drivers.
Common discounts include bundling home and auto insurance (usually 10 to 25 percent off), maintaining continuous coverage without lapses (5 to 10 percent), completing a defensive driving course (5 to 15 percent), and installing anti-theft or safety devices in your vehicle (5 to 10 percent). Some insurers offer usage-based programs that monitor your driving habits through a mobile app or plug-in device and reward safe driving with discounts of up to 30 percent, though these programs are optional.
Your credit score also affects your rate in Arizona. Insurers use credit-based insurance scores (different from your credit score but correlated with it) to predict the likelihood you will file a claim. Drivers with poor credit typically pay 20 to 50 percent more than those with excellent credit for identical coverage. If your credit is weak, improving it over time will lower your insurance costs.
What happens if you drive without insurance in Arizona
Driving without proof of insurance in Arizona is a civil traffic violation. A first offense carries a fine of $250 and requires you to show proof of insurance to the court within a specified time frame. A second violation within three years results in a $500 fine, and a third violation within three years is a misdemeanor with fines up to $2,500 and possible jail time.
If you are caught driving uninsured and cause an accident, you become personally liable for all damages. The other driver can sue you directly for medical bills, vehicle repairs, lost wages, and pain and suffering. A judgment against you can result in wage garnishment and a lien on your property. Arizona also suspends your driver's license if you are found at fault in an accident and cannot pay the damages.
If your insurance lapses — even for a few days — you are driving uninsured. Many drivers do not realize their policy has lapsed until they are pulled over or have an accident. Set up automatic payments or calendar reminders to renew before your policy expires. If you cannot afford your current premium, contact your insurer about payment plans or lower-coverage options rather than letting your policy lapse.
SR-22 filing requirements for Arizona drivers with DUI or serious violations
An SR-22 is a certificate of financial responsibility that you file with the Arizona Department of Transportation to prove you carry the required insurance. You do not need an SR-22 unless the state orders one — typically after a DUI conviction, reckless driving conviction, or multiple traffic violations within a short period.
Your insurance company files the SR-22 on your behalf when you request it. There is usually a small filing fee ($15 to $25) added to your premium. The SR-22 itself does not increase your rate, but the reason you need it — a DUI or serious violation — will. Drivers with a DUI conviction typically pay 100 to 300 percent more for insurance than drivers with clean records. You must maintain the SR-22 for the period the court specifies, usually three years. If your policy lapses or you cancel it, your insurer must notify the state, and your license will be suspended again.
If you need an SR-22, shop around before buying a policy. Some insurers specialize in high-risk drivers and offer better rates than others. The difference between the cheapest and most expensive quote for the same coverage can be $500 to $1,000 per year.
Comparing Arizona car insurance companies and coverage options
Arizona has dozens of insurers operating in the state, from national carriers like State Farm and Geico to regional companies and specialty insurers. There is no single "best" company — the cheapest option for one driver may be expensive for another because each insurer uses different rating models. A driver with a clean record might get the best rate from one company, while a driver with an accident gets the best rate from a different one.
The most efficient way to find the lowest rate is to get quotes from at least three to five insurers for the same coverage limits. Most companies offer quotes online in minutes without requiring a phone call. When comparing quotes, make sure the coverage limits, deductibles, and discounts are identical across all quotes so you are comparing apples to apples. A $500 deductible will always be cheaper than a $250 deductible, but it means you pay more out of pocket if you have a claim.
Beyond price, consider the insurer's customer service reputation and claims process. The National Association of Insurance Commissioners (NAIC) publishes complaint ratios for each insurer, showing how many complaints they receive per 1,000 policies sold. You can also check reviews on independent sites, though remember that people are more likely to leave reviews after a bad experience than a good one. If you have a complex claim or need to speak with someone regularly, a local agent may be worth a slightly higher premium.
How to update your Arizona car insurance after a move or life change
If you move to a different city or county in Arizona, your insurance rate may change because insurers use location-based risk factors. Urban areas typically have higher rates than rural areas due to higher accident and theft rates. Notify your insurer within 30 days of moving so your policy reflects your new address. Some insurers will not process claims if your address on file does not match where the accident occurred.
Life changes also affect your rate. Getting married, turning 25, adding a teenage driver to your policy, or buying a different vehicle all trigger rate changes. Some changes lower your rate (marriage, reaching 25, switching to a safer vehicle), while others raise it (adding a young driver, buying a sports car). When you experience a major life change, ask your insurer to recalculate your rate — you may discover new discounts you did not know about.
If you are buying a new or used car, get an insurance quote before you finalize the purchase. The difference in insurance cost between two vehicles can be $500 to $1,500 per year. A sports car or luxury sedan will cost significantly more to insure than a sedan or SUV with the same safety ratings. Checking the insurance cost as part of your purchase decision helps you avoid surprises when you bind coverage.
Frequently Asked Questions
Can I get car insurance in Arizona without a driver's license?
No. You must have a valid Arizona driver's license or permit to purchase car insurance. If you are a new resident without an Arizona license, you have 10 days to obtain one. If you are waiting for your license, some insurers will bind coverage temporarily, but you cannot legally drive until your license is issued.
What is the difference between liability and collision coverage?
Liability coverage pays for damage you cause to someone else's vehicle or property, plus their medical bills if they are injured. Collision coverage pays for damage to your own vehicle when you hit another car or object, regardless of who is at fault. Liability is required; collision is optional unless you have a loan or lease.
Do I need to carry my insurance card in my vehicle at all times?
Yes. Arizona law requires you to show proof of insurance when pulled over by police or after an accident. You can show a physical card, a digital copy on your phone, or a screenshot of your policy. If you cannot produce proof, you will be cited for driving without insurance even if you actually have a policy.
How long does an accident stay on my driving record in Arizona?
An accident typically stays on your record for three to five years, depending on the insurer. After three years, most insurers will remove it from your rate calculation, though it may still appear on your record if you request a copy. A serious accident (injury or high property damage) may affect your rate for longer.
What should I do if I cannot afford my car insurance premium?
Contact your insurer and ask about payment plans, lower deductibles, or reduced coverage options. You can also shop for quotes from other insurers — rates vary significantly. If you are struggling financially, some nonprofits and community organizations offer information with insurance costs, though availability varies by county.
