CSAA, GEICO and Trubull offer the best car insurance in Arizona, according to our research of the state’s providers.

CSAA: best for cheap minimum coverage

CSAA offered our sample driver an average rate of $335 a year for state-minimum car insurance. That’s more than $300 a year cheaper than the Arizona average for this kind of policy.

Although it’s possible you’ve never heard of CSAA, you probably have heard of AAA. CSAA is affiliated with AAA, so buying coverage from CSAA gives you access to the stability, service and discounts AAA has become known for over the 106 years it has been in business.

GEICO: best for cheap full coverage

GEICO is a good option if you’re looking for minimum liability coverage, too. The average annual rate it offered was almost as low as what the leader in this area, CSAA, offered. Also, at $351 a year, it was nearly $300 lower than the state average.

Trumbull: runner-up for cheapest rates

Trumbull is another good option for people looking for cheap auto insurance in Arizona. And this is true whether you’re looking for cheap state-minimum coverage or cheap full coverage.

The average annual rate Trumbull offered our sample driver for minimum coverage was $429. That’s $94 per year more than what CSAA offered, but it’s also $213 per year less than the state average.

Also, the average annual rate Trumbull offered our sample driver for full coverage was $808. This is $64 per year more than what GEICO offered and $432 per year less than the state average.

Something to keep in mind about Trumbull is that it’s an affiliate of The Hartford. As you may know, The Hartford works with AARP to provide auto and home insurance to the latter organization’s members.

What are Arizona’s minimum car insurance requirements?

Arizona law requires drivers to show proof of financial responsibility before they can register a vehicle with the state. Most people do that by getting at least 15/30/10 car insurance coverage.

What does 15/30/10 mean when it comes to auto insurance? It means your policy must include a minimum of:

  • $15,000 of bodily injury liability coverage per person.
  • $30,000 of bodily injury liability coverage per accident. 
  • $10,000 of property damage liability coverage.

These are just the state’s minimum auto insurance requirements, however; you can buy more coverage if you want to do so. Depending on your car’s value and several other factors, you may want or even need to buy comprehensive or collision coverage as well.

If you’d rather not buy car insurance to prove financial responsibility as an Arizona driver, you can do so with a bond, a certificate of deposit or cash in the amount of $40,000.

Penalties for driving without insurance in Arizona

Driving without car insurance in Arizona can be costly.

If the state catches you driving without insurance or some other proof of financial responsibility, it could:

  • Ticket and fine you between $500 and $1,000.
  • Suspend your vehicle registration and driver’s license.
  • Impound your vehicle.

Also, if you cause an accident without auto insurance, you might be sued. And if you decide to buy coverage down the road, you may pay higher rates than you would otherwise.
