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

This bill requires insurers writing private passenger auto insurance in New Jersey to revise their territorial rating plans. It mandates that new territories be defined using contiguous zip code+4 areas (instead of standard zip codes) that follow municipal boundaries as closely as possible, with a maximum of 100 territories per map. Insurers must consider factors like traffic density, population, driving environment similarities, and loss experience - while avoiding unfair subsidies between areas with different risk profiles. The change allows for more precise risk-based pricing by enabling insurers to create smaller, more geographically specific rating areas than current rules permitted.
