What Is Minimum Coverage Car Insurance Insurance?
Minimum coverage car insurance in Arizona pays for injuries and property damage you cause to other people in an accident where you are at fault. It does not pay to repair or replace your own vehicle, cover your own medical bills, or protect you if the other driver has no insurance. The state requires you to carry at least $25,000 per person for bodily injury, $50,000 per accident for all injuries combined, and $15,000 for property damage to meet registration and legal driving requirements.
- You rear-end another car at a stoplight in Phoenix. The other driver has $18,000 in medical bills and $9,000 in vehicle damage. Your minimum liability policy pays the full $27,000 because it falls within your 25/50/15 limits. Your own vehicle, which sustained $6,000 in front-end damage, is not covered — you pay that repair cost yourself or file through your own collision coverage if you carry it.
- You cause a three-car accident on I-10. Two people are injured — one with $30,000 in medical bills, another with $22,000. Your minimum policy pays $25,000 to the first person and $22,000 to the second, totaling $47,000 under your $50,000 per-accident limit. You are personally liable for the remaining $5,000 owed to the first injured party because their bills exceeded your $25,000 per-person limit.
- An uninsured driver runs a red light and totals your car. You have minimum liability coverage only. Your policy does not pay for your vehicle damage or your medical bills because liability coverage only pays for harm you cause to others. Without uninsured motorist coverage or collision coverage, you pay all repair and medical costs out of pocket or pursue the at-fault driver directly in court.
Who Needs Minimum Coverage Car Insurance Insurance?
Minimum coverage makes sense if you drive an older vehicle worth less than $3,000, have no car loan or lease requiring collision and comprehensive coverage, and can afford to replace your vehicle out of pocket if it is totaled. It is also the required floor for drivers who need to meet Arizona registration and proof-of-insurance rules at the lowest possible premium.
Compare your vehicle's current value to the annual cost difference between minimum liability and full coverage. If your car is worth $4,000 and full coverage costs $800 more per year than minimum, you are paying 20 percent of the vehicle's value annually to insure it — minimum coverage may be the better financial choice. If your car is worth $15,000 and the difference is $600 per year, full coverage protects you from a total loss for 4 percent of the vehicle's value, which is harder to replace out of pocket.
How Much Does Minimum Coverage Car Insurance Insurance Cost?
Minimum liability coverage in Arizona typically costs $45 to $85 per month, or $540 to $1,020 annually, depending on your driving record, age, and location within the state.
- Driving record — a single at-fault accident or speeding ticket can increase minimum coverage premiums by 15 to 30 percent.
- Age and experience — drivers under 25 and over 70 typically pay higher rates for the same minimum limits due to statistical accident risk.
- ZIP code — urban areas like Phoenix and Tucson show higher minimum premiums than rural counties due to accident frequency and repair costs.
- Credit-based insurance score — Arizona allows insurers to use credit history in pricing, which can raise or lower your minimum premium by 20 percent or more.
- Vehicle type — while minimum coverage does not insure your own vehicle, the car you drive still affects liability rates because higher-value vehicles statistically correlate with higher injury and property damage payouts in accidents you cause.
