It shall be unlawful for any person to drive on any highway a motor vehicle registered in the Commonwealth and manufactured or assembled after January 1, 1935, and designed or used for the purpose of carrying persons for compensation or hire or as a public conveyance to transport school children and others, unless such vehicle is equipped with safety glass wherever glass is used in doors, windows, and windshields. It shall be unlawful to drive on any highway any motor vehicle registered in the Commonwealth, manufactured or assembled after January 1, 1936, unless the vehicle is equipped with safety glass approved by the Superintendent, or meets the standards and specifications of the American National Standards Institute, Incorporated, or the regulations of the federal Department of Transportation whenever glass is used in doors, windows, and windshields. The term “safety glass” as used in this section shall mean any product composed of glass so manufactured, fabricated or treated as substantially to prevent shattering and flying of the glass when struck or broken. The Commissioner shall maintain a list of types of glass approved by the Superintendent as conforming to the specifications and requirements for safety glass as set forth in this section and shall not issue a license for or relicense any motor vehicle subject to the provisions herein stated unless such motor vehicle is equipped as herein provided with the approved type of glass. No glazing material other than safety glass shall be used in any motor vehicle registered in the Commonwealth, except that the Superintendent may permit safety glazing materials other than glass to be used in lieu of safety glass in portions of motor vehicles, trailers, and semitrailers designated by him, provided any such material bears a trade name or identifying mark, and has been submitted to and approved by the Superintendent. If any person drives any vehicle in violation of this section while under a certificate issued by the State Corporation Commission, in addition to the penalty provided in § 46.2-113, the certificate of such person may, in the discretion of the State Corporation Commission, be suspended until this section is satisfactorily complied with. Replacement safety glass installed in any part of a vehicle other than the windshield need not bear a trademark or name, provided (i) the glass consists of two or more sheets of glass separated by a glazing material, (ii) the glass is cut from a piece of approved safety glass, and (iii) the edge of the glass can be observed.
