GM National Insurance Company filed in Michigan on September 5, 2025, to revise its Personal Auto program, effective November 10, 2025.

The filing updates the TNC/DNC endorsement to align with the policy, clarifies residency requirements with a new Declaration of Intent to Reside form, and separates the work loss waiver into its own standalone form for insureds age 60+ not earning income. The program also refreshes its PIP Coverage Options form for operational efficiency.

The TNC/DNC endorsement specifies limited business use coverage with exclusions across periods of operation, while new language strengthens compliance on garaging and residency. Telematics and on-board data sources are noted for claims investigation. GM National is domiciled in Illinois.
