What Arizona Law Actually Requires
You need proof of insurance to register a car in Arizona, and the state sets a specific liability floor: $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $15,000 for property damage. That triplet satisfies the Motor Vehicle Division. It does not satisfy a multi-vehicle crash with injuries, and it does not satisfy most lenders if the car is financed.
The minimum exists to keep uninsured drivers off the road, not to cover what a serious accident actually costs. Arizona does not require collision, comprehensive, uninsured motorist, or personal injury protection coverage. Those are optional. The only mandate is liability at the floor, and the floor is where most budget policies start.
“The minimum satisfies the MVD, not the lawsuit: when your at-fault crash exceeds the limits, the injured party sues you for the difference.”

Arizona Per-Person Injury Minimum
Arizona Revised Statutes 28-4009 sets the bodily injury minimum at $25,000 per person. A multi-day hospital stay after a serious crash routinely exceeds that limit, and the at-fault driver pays the difference out of pocket or through wage garnishment.

Legal Compliance vs Full Exposure
The state minimum protects you from a registration suspension and a ticket for driving uninsured. It does not protect your assets if you cause a crash that injures multiple people or totals a newer vehicle. The per-person limit caps what your policy pays for each injured person; the per-accident limit caps the total payout no matter how many people are hurt. The property damage limit caps what your policy pays to repair or replace the other driver's vehicle.
When the bills exceed those limits, the injured party can sue you for the difference. Arizona courts can garnish wages, place liens on property, and seize bank accounts to satisfy a judgment. The minimum satisfies the law. It does not satisfy the judgment.
Most cost-conscious drivers buying minimum coverage own older vehicles outright and have calculated that collision and comprehensive premiums exceed the car's replacement value. That math is sound. The liability decision is different: liability protects your income and assets, not the car. Dropping collision on a paid-off car with low market value is rational. Carrying only the state minimum when you have wages or property a lawsuit could reach is a structural exposure.
The minimum satisfies the MVD, not the lawsuit. If your at-fault crash exceeds the limits, the injured party sues you directly for the difference.
Lapse Mechanics and Reinstatement Costs
Arizona requires continuous coverage once you register a vehicle. If your policy cancels for nonpayment, the carrier reports the lapse to the Motor Vehicle Division within 10 days. The MVD suspends your registration and mails a notice. Driving on a suspended registration is a Class 2 misdemeanor, and a traffic stop triggers impound fees on top of the reinstatement cost.
Reinstating after a lapse requires proof of future financial responsibility, which means filing an SR-22 certificate. The SR-22 itself costs $15 to $25 to file, but the real cost is the premium increase: carriers classify SR-22 filers as high-risk, and rates typically double. The SR-22 filing period lasts three years from the reinstatement date. The base reinstatement fee is $10, but late fees and impound costs stack quickly if you drive before reinstating.
The cheapest policy that lapses becomes the most expensive decision a budget driver makes. Missing one installment triggers a cancellation notice with a deadline, usually 10 to 15 days. Reinstating before the carrier reports the lapse to the state avoids the SR-22 requirement and the three-year high-risk classification. Paying the installment late costs a late fee; letting it lapse costs three years of doubled premiums.

Carriers Writing Arizona Budget Policies
Arizona has 25 carriers writing nonstandard and standard-tier policies for cost-conscious drivers, including Acceptance, Bristol West, Dairyland, GAINSCO, Geico, Infinity, Kemper, Mercury General, National General, Progressive, and The General. Quoting multiple carriers in the right tier produces the lowest rate because accident surcharges and tier placement vary widely between insurers.

When Higher Limits Make Sense
Raising liability limits costs less than most drivers expect because the premium increase is smaller than the coverage increase. Moving from $25,000/$50,000 per-person and per-accident limits to $50,000/$100,000 typically adds $10 to $20 per month, but it doubles the protection. The property damage increase from $15,000 to $25,000 or $50,000 adds $5 to $10 per month.
Higher limits make sense when you own a home, have significant savings, or earn wages a garnishment could reach. Arizona allows wage garnishment up to 25% of disposable earnings to satisfy a judgment. If you net $2,000 per month, a garnishment can take $500 per month until the judgment is paid. A $40,000 judgment takes 80 months to satisfy at that rate, and interest accrues during the garnishment period.
The trade-off is honest in both directions: higher limits cost more per month but protect more of your income and assets if you cause a serious crash. Minimum limits cost less per month but expose everything you own above the floor. The right choice depends on what you could actually lose, not what the state requires.
Uninsured Motorist Coverage
Arizona does not require uninsured motorist coverage, but 10.6% of Arizona drivers are uninsured according to 2023 Insurance Research Council data. Uninsured motorist coverage pays your medical bills and lost wages when an uninsured driver hits you and flees or cannot pay. It also covers underinsured motorist crashes, where the at-fault driver carries minimum liability but your bills exceed their limits.
Uninsured motorist coverage costs $5 to $15 per month for minimum limits and protects you without requiring you to sue the other driver. If you carry only liability coverage and an uninsured driver totals your car, you pay to replace it yourself. If that same driver injures you, you pay your own medical bills unless you carry uninsured motorist coverage. Budget drivers often skip this coverage to minimize premiums, but it is the only protection you have when the other driver has no insurance or insufficient limits.
Compare Carriers in Your Tier
Arizona budget policies are written by nonstandard and standard-tier carriers, and rates vary widely between them even for identical coverage. Geico, Progressive, State Farm, and Allstate write standard-tier policies for drivers with clean records. Acceptance, Bristol West, Dairyland, GAINSCO, Infinity, Kemper, Mercury General, National General, and The General specialize in nonstandard policies for drivers with violations, lapses, or SR-22 filings. The cheapest carrier for a clean-record driver is rarely the cheapest for a driver with a DUI or lapse on record.
Get quotes from at least three carriers in your tier. Online quotes work for most standard-tier carriers; nonstandard-tier carriers often require a phone call or broker. Installment fees add $5 to $10 per month to the total cost if you pay monthly rather than in full, and some carriers charge higher installment fees than others. The lowest advertised rate is not always the lowest total cost once installment fees are included. Ask for the total cost per month, not just the base premium, before you buy.
What Each Coverage Component Does
Bodily injury per person ($25,000 minimum) pays medical bills, lost wages, and pain-and-suffering damages for each person you injure in an at-fault crash. If one person's bills reach $40,000, your policy pays $25,000 and you owe $15,000. The per-accident cap ($50,000 minimum) limits the total your policy pays no matter how many people are injured. If three people are hurt and their combined bills reach $90,000, your policy pays $50,000 total and you owe $40,000.
Property damage ($15,000 minimum) pays to repair or replace the other driver's vehicle and any property you damage. Replacing a totaled mid-size SUV costs more than the floor. If the other driver's vehicle is worth $28,000, your policy pays $15,000 and you owe $13,000. Collision coverage on your own policy pays for your own vehicle; liability property damage pays for theirs. Budget drivers often drop collision on older cars but still need liability property damage because the other driver's car might be new.

What happens if I drive without insurance in Arizona?
Driving without insurance in Arizona is a Class 2 misdemeanor. First offense penalties include a $500 fine, three-month registration suspension, and a three-year SR-22 filing requirement. The SR-22 typically doubles your premium for three years, making the total cost of one uninsured violation $3,000 to $5,000 over the filing period.
Does Arizona require SR-22 filing after a DUI?
Yes. Arizona requires SR-22 filing for three years after a DUI conviction, measured from the conviction date. The SR-22 itself costs $15 to $25 to file, but carriers classify SR-22 filers as high-risk and premiums typically double. The filing period restarts if your policy lapses during the three years.
Can I drop collision coverage on an older car in Arizona?
Yes, if you own the car outright. Arizona does not require collision or comprehensive coverage. Lenders require both on financed vehicles. Dropping collision makes sense when the annual premium exceeds 10% of the car's market value, but you still need liability coverage because that protects your assets if you cause a crash.
How much does it cost to reinstate a suspended registration in Arizona?
The base reinstatement fee is $10. If the suspension was caused by a lapse in coverage, you must also file an SR-22 certificate ($15 to $25) and maintain it for three years. The SR-22 filing requirement typically doubles your premium, making the total three-year cost $3,000 to $6,000 depending on your driving record and vehicle.
Do I need uninsured motorist coverage in Arizona?
Arizona does not require it, but 10.6% of Arizona drivers are uninsured. Uninsured motorist coverage pays your medical bills and lost wages when an uninsured driver hits you. It costs $5 to $15 per month for minimum limits and is the only protection you have when the other driver cannot pay.
What is the cheapest car insurance in Arizona?
The cheapest carrier varies by driving record, vehicle, and location. Geico, Progressive, and State Farm typically offer the lowest rates for drivers with clean records. Acceptance, Bristol West, Dairyland, and The General specialize in nonstandard policies for drivers with violations or lapses. Quote at least three carriers in your tier to find the lowest rate.
