(iv) the named insured or other operator of the motor vehicle insured under the policy, or the insurer thereof, was reimbursed by or on behalf of a person responsible for the accident or has a judgment against such person.
Where more than one motor vehicle in a household is insured by the same insurer, the number of accidents which would permit conditional renewal or non-renewal shall, as for the aggregate, be increased by two for each additional motor vehicle insured. For the purposes of this paragraph accidents occurring as a result of the use or operation of a motor vehicle in response to an emergency, where the operator was responding to a call of duty as a paid or volunteer member of any police or fire department, first aid squad, or of any law enforcement agency; or was performing any other governmental function in a public emergency, shall not be accidents which afford an insurer the right to cancel or to refuse to renew.
