Section 215 ILCS 5/388a - Group vehicle insurance defined(a) Group vehicle insurance is declared to be that form of vehicle insurance covering not less than 10 employees, members, or employees of members, written under a master policy issued to any governmental corporation, unit, agency or department thereof, or to any corporation, co-partnership, individual employer, or to any association upon application of an executive officer or trustee of such association having a constitution or by-laws and formed in good faith for purposes other than that of obtaining insurance, where officers, members, employees, employees of members or classes or department thereof, may be insured for their individual benefit. In addition a group vehicle policy may be written to insure any group which may be insured under a group life insurance policy. The term "employees" shall include the officers, managers and employees of subsidiary or affiliated corporations, and the individual proprietors, partners and employees of affiliated individuals and firms, when the business of such subsidiary or affiliated corporations, firms or individuals, is controlled by a common employer through stock ownership, contract or otherwise.(b) A group vehicle insurance policy may provide physical damage coverage, liability coverage, or a combination of physical damage and liability coverage. A group physical damage policy and a certificate incidental to that policy, issued in accordance with this Section, does not meet the mandatory insurance requirements under the Illinois Vehicle Code and must contain a warning to the consumer that the policy does not comply with those requirements.
