GM National Insurance Company filed a rules-only update to its Florida private passenger auto underwriting guidelines, effective April 29, 2026, for new business and June 28, 2026, for renewals.

The changes introduce new vehicle eligibility restrictions, including ineligibility for vehicles used primarily for peer-to-peer car sharing and new business limits for households where the number of vehicles exceeds the number of drivers plus three. The company also clarified that vehicles not owned or leased by a resident relative are ineligible and expanded app-based rideshare and delivery restrictions to apply to renewal business.

The filing does not include rate changes and was submitted under Florida’s file-and-use provision.

State filings indicate GM’s insurance book exceeds 18,000 policies, with Texas dominating the portfolio at $12.3 million in premium and 8,417 policies, representing about 55% of total premium and 47% of policies. The next tier is much smaller, led by Arizona with $3.15 million and 1,869 policies, Illinois with $2.30 million and 2,511 policies, and Georgia with $1.91 million and 1,193 policies.
