Within what time period after issuance of a new private passenger auto policy in New Jersey may an insurer cancel for any lawful underwriting reason without limitation to enumerated statutory grounds?

Why this is the answer

Under N.J.S.A. 17:29C, the first 90 days of a new private passenger auto policy is the underwriting window during which the insurer may cancel for any lawful underwriting reason on proper notice. After 90 days, mid-term cancellation is restricted to enumerated statutory grounds.
