Revises territorial rating plans used by insurers writing private passenger automobile insurance.

This bill updates how automobile insurance companies in New Jersey group geographic areas to set insurance rates. It requires insurers and rating organizations to create new territorial rating plans that use more detailed zip code+4 boundaries instead of broader zip codes, while limiting the total number of territories to a maximum of 100. The law also mandates that these territories be defined in ways that reflect differences in driving conditions, traffic patterns, and population density, and that they avoid unfair discrimination between neighboring areas with similar environments. The changes will take effect 120 days after the bill is enacted and apply to rating plans filed after that date.
