Windshields and wind screens. Face shields. Goggles

(a) The "United States of America Standards Institute (formerly American Standards Association) Safety Code for Safety Glazing Materials for Glazing Motor Vehicles Operating on Land Highways, Z26.1-1966" is adopted as the standard for flexible plastic glazing material which shall be used in windshields and wind screens on motorcycles. All wind screens and windshields shall be constructed and maintained so as to provide the operator with an unobstructed view of the highway. Materials other than those meeting the requirements of this standard may be used in areas below that which is necessary to provide an unobstructed view of the highway and in any supporting frame. (b) All face shields shall be made of plastic material and shall attach to the wearer's helmet. Such face shield shall cover the wearer's face from above both eyes to a point below both eyes on a horizontal line even with the tip of the nose. During such periods as vehicles are required to display lights, only face shields of non-tinted (clear) plastic shall be used. No material which will obscure or reduce the wearer's field of vision shall be affixed to or be contained in such face shield other than such devices as may be necessary for attachment to the helmet. (c) All goggles or glasses shall be equipped with lenses of plastic or shatter-proof glass and shall be so designed as to shield the eyes of the wearer and deflect small objects, bugs or other similar material. All glasses and goggles shall be so designed as to allow the wearer an angle of vision of not less than 105 degrees and shall be worn in such a manner as not to be accidentally dislodged. During such periods as vehicles are required to display lights only goggles or glasses with non-tinted (clear) lenses shall be used.
