    (b) Windshields required. Each bus, truck and truck-tractor shall be 

equipped with a windshield. Each windshield or portion of a multi-piece 

windshield shall be mounted using the full periphery of the glazing 

material.

    (c) Windshield condition. With the exception of the conditions 

listed in paragraphs (c)(1), (c)(2), and (c)(3) of this section, each 

windshield shall be free of discoloration or damage in the area 

extending upward from the height of the top of the steering wheel 

(excluding a 51 mm (2 inch) border at the top of the windshield) and 

extending from a 25 mm (1 inch) border at each side of the windshield or

through the colored or tinted glazing is not less than 70 percent of the 

light at normal incidence in those portions of the windshield or windows 

which are marked as having a parallel luminous transmittance of not less 

than 70 percent. The transmittance restriction does not apply to other
