It's mandatory to have a policy that meets Arizona's minimum auto insurance requirements. Driver's license suspension for up to one year. If you don't have car insurance in Arizona, the state will suspend your driver's license, registration, and registration for one year. Unfortunately, in this case, if you don't have car insurance and you're caught doing it and you're convicted for it, the penalty alone can be more expensive than what it would have cost you initially to purchase an auto insurance policy.
In Arizona, law enforcement officers can request proof of insurance during traffic stops or after a car accident. It is not a type of car insurance, but rather proof that the driver has purchased and maintains the minimum required amount of car insurance. This shows your future financial responsibility by verifying with the state that you have paid the minimum car insurance coverage required.
