If, on or before January 1, 1946, every insurance carrier authorized to write automobile bodily injury liability insurance in this State shall not subscribe to an assigned risk plan approved by the Director of Insurance, providing that no carrier may withdraw therefrom after approval of the Director, the Director of Insurance shall, when he finds that an application for bodily injury or property damage insurance by a risk, which may become subject to this Act or is a local public entity subject to the Local Governmental and Governmental Employees Tort Immunity Act, and in good faith is entitled to such insurance, has been rejected by 3 insurance carriers, designate an insurance carrier which shall be obligated to issue forthwith its usual form of policy providing such insurance for such risk. The Director shall make equitable distribution of such assignments among insurance carriers proportionate, so far as practicable, by premiums to the respective net direct automobile bodily injury premium writings of the carriers authorized to do business in this State. The Director of Insurance shall establish rules and regulations for the administration of the provisions of this Section.
If any carrier refuses or neglects to comply with the provisions of this Section or with any lawful order or ruling made by the Director of Insurance pursuant to this Section, the Director may, after notice and hearing, suspend the license of such carrier to transact any insurance business in this State until such carrier shall have complied with such order.
