Cheap Liability Car Insurance in Phoenix 

25+ Years of Trusted Service*

Auto insurance rates in Phoenix have been steadily rising, with year-over-year rates up a whopping17%. The current yearly cost of a full coverage policy in Phoenix, Arizona, is $3,757, or $313 per month. This has pushed many drivers to seek cheap liability car insurance in Phoenix. 

Minimum liability coverage is significantly cheaper than a full coverage car insurance policy, with average rates at about $182 per month. For good drivers with excellent credit who take advantage of discounts, they can get those rates even lower. This article takes a deep dive into liability-only coverage in The Valley Of The Sun and how to get the best policy possible at the lowest rates.  

Arizona’s Minimum Liability Requirements

Every driver in Arizona must carry at least the state-mandated minimum coverage. The required limits are $25,000 for bodily injury per person, $50,000 for bodily injury per accident, and $15,000 for property damage. 

These numbers, known as 25/50/15, protect other people and their property if you cause an accident. They don’t pay for your own car or medical expenses, so this type of insurance is best suited for drivers with older cars or those who simply need to meet legal obligations.

Driving without at least these minimums can lead to license suspension, fines, and even impoundment of your vehicle. Keeping a valid policy active is not only the law but also the easiest way to protect yourself from major financial trouble.

Travelers – A Great Option To Consider

Travelers often provides the lowest liability rates in Phoenix for seniors and drivers with clean records. It offers many discounts, such as autopay, good driver, and multi-policy savings, which make it appealing for people who like to keep coverage simple and affordable.

GEICO – Great for Discount Hunters 

GEICO’s prices in Phoenix are very competitive, and its online quoting system is among the fastest. The company offers discounts for good driving, bundling with renters insurance, and maintaining good credit. GEICO tends to be especially affordable for experienced drivers and homeowners.

Mercury ins logo

Mercury Insurance – Cheap Local Option 

Mercury Insurance performs well in many Phoenix ZIP codes, particularly for older cars and long-term drivers. While its online tools are simpler than national brands, Mercury’s local focus and personal service make it a good choice for people who prefer working with an agent.

Root ins logo

Root Insurance – Perfect for Safe, Low-Mileage Drivers 

Root sets rates based on how well you actually drive. It uses a smartphone app to track your habits for a few weeks and then rewards cautious, low-mileage drivers with lower premiums. Root is best for people who rarely drive or who have smooth driving habits and want a customized rate.

Pro Tip: Use a Telematics Program to Save More

One of the fastest ways to lower your Phoenix car insurance cost is to join a usage-based or telematics program. These programs track your driving habits—how smoothly you brake, how fast you drive, and how often you’re on the road. The safer you drive, the less you pay.

Travelers, GEICO, and Root all have versions of this system. Drivers who participate can save anywhere from 10% to 30% on their premiums. For liability-only coverage, this discount can easily bring a $95 monthly bill down to around $75, making it one of the most effective savings tools available.

How Zip Codes Affect Rates in Phoenix

Phoenix’s large size means that car insurance rates can vary dramatically from one neighborhood to another. Central Phoenix areas with more traffic and higher theft rates tend to cost more, while suburban ZIP codes often benefit from lower premiums. Drivers who park in a garage or live in gated communities may also receive small reductions. If you’ve moved recently or plan to, updating your garaging address can sometimes lower your rate instantly.

Tips for Teen Drivers in Phoenix

Teen drivers pay more for insurance because they’re statistically more likely to have accidents. However, liability-only coverage helps keep the cost manageable. Parents can save money by adding teens to an existing family policy instead of getting a separate plan. Teens who maintain good grades usually qualify for a “good student” discount, and completing a defensive driving course can help, too. Choosing an older, safe car with lower repair costs will also reduce premiums. After a year of clean driving, most insurers lower rates automatically.

How Senior Drivers Can Save On Phoenix Liability Car Insurance 

Seniors often enjoy steady driving records, but premiums can creep up slightly with age. To keep costs low, seniors should complete a defensive driving refresher course, which many insurers reward with lower rates. If you’re retired and drive less, ask about low-mileage discounts. Staying with the same insurer for several years can earn loyalty discounts, and bundling home and auto coverage adds even more savings. Seniors who set up automatic payments or annual billing also avoid lapse penalties and late fees.

When Minimum Coverage Isn’t Enough

Arizona’s 25/50/15 liability minimums meet the law but don’t always cover real-world accident costs. If you total a newer car or cause serious injuries, expenses can easily exceed those limits. Increasing your liability limits to 50/100/50 or even 100/300/50 provides far better protection and usually costs only a few dollars more per month. Drivers with savings, property, or other assets should seriously consider higher limits to avoid personal financial exposure.

Add applicable discounts such as telematics, bundling, or defensive driving.

Review your rates every six months to ensure you’re still getting the best deal.
