HiRoad Assurance Company has filed for an overall 4.7% rate increase on its auto program in Arizona, impacting 6,358 policyholders and $16.4 million in written premium. The proposed changes take effect August 14, 2025, for new business and September 18, 2025, for renewals.
The filing adjusts base rates and fixed expenses by coverage, with an indicated need of 4.5%. HiRoad incorporated ISO Arizona loss trends and State Farm’s Arizona data due to its own limited experience.
Actuarial exhibits include base rate development, auto indications, and credibility calculations. The Arizona Department of Insurance checklist flagged requirements around actuarial support for discounts and fees, and the prohibition of “upon approval” effective dates.
