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

This bill (A5846) revises how New Jersey insurers define geographic areas for private passenger auto insurance pricing. It requires insurers to create new territorial rating plans using contiguous zip code+4 areas (instead of standard zip codes) that follow municipal boundaries, with a maximum of 100 territories per map - up from the current 50. These changes aim to create more precise risk-based pricing by better reflecting local driving conditions like traffic density and population mix. The bill directly affects auto insurers operating in New Jersey and the Commissioner of Banking and Insurance, who must establish regulations to implement these standards.
