Flynn Greathouse warns Arizona drivers about UM/UIM coverage gaps

By AI, Created 4:20 PM UTC, May 18, 2026, /AGP/ – Phoenix personal injury firm Flynn Greathouse says Arizona drivers may be paying for auto insurance protection they cannot fully use because of low state minimums and anti-stacking rules. The firm is urging motorists to review UM/UIM policies after explaining how coverage disputes can affect compensation after a crash.

Why it matters: - Arizona’s minimum auto insurance limits can leave injured drivers and passengers exposed to major out-of-pocket costs after a serious crash. - UM/UIM coverage is meant to help fill that gap, but anti-stacking rules can reduce how much policyholders can recover. - The issue matters most for households with multiple vehicles and multiple policies that may not deliver the protection consumers expect.

What happened: - Flynn Greathouse published guidance for Arizona motorists on uninsured and underinsured motorist coverage. - The Phoenix-based personal injury firm said the guidance is aimed at helping drivers understand how policy language and state law can affect compensation after a collision. - The firm also says it is expanding to serve clients nationwide.

The details: - Arizona’s minimum liability limits under A.R.S. § 28-4009 are $25,000 per person, $50,000 per accident, and $15,000 for property damage. - The firm says those minimums often fall short of covering emergency treatment, long-term rehabilitation and lost wages in severe collisions. - Many drivers buy UM/UIM coverage to address that shortfall. - Households with multiple vehicles often buy several policies and may assume the coverage can be stacked. - Anti-stacking provisions in A.R.S. § 20-259.01(H) limit total payout amounts available to policyholders. - A recurring dispute involves whether multiple people who jointly buy household policies count as a single insured party. - When insurers take that position, anti-stacking clauses can prevent insureds from combining limits across policies. - The firm says that can leave consumers paying premiums for multiple policies while being barred from using overlapping coverage. - Riah Greathouse, co-founder of Flynn Greathouse and a former prosecutor, said insurers use dense policy language and technical arguments to avoid paying claims. - James Flynn, co-founder and litigator, said families buy extra UM and UIM coverage to protect loved ones and that Arizona’s minimums are not enough. - Flynn Greathouse says it focuses exclusively on car, truck, motorcycle and rideshare accident cases. - The firm says its lawyers help injured clients deal with insurance adjusters, gather evidence, establish liability and negotiate for compensation.

Between the lines: - The release frames Arizona UM/UIM disputes as a consumer-protection issue, not just a coverage dispute. - The anti-stacking fight can turn on how a policy defines the insured household, which makes contract wording especially important. - The messaging suggests the firm sees policy review as a way to surface coverage problems before a crash exposes them.

What’s next: - Flynn Greathouse is urging Arizona drivers to review their auto policies immediately and consult legal professionals about their coverage limits. - Injured motorists can contact the firm at (602) 777-3476 for a free virtual consultation. - The firm says it will continue monitoring legal precedents that affect UM/UIM coverage and stacking disputes. - Readers can view the company’s announcement.
