In this section—glazing—
means material that may be used in a windscreen, window or interior partition of a heavy motor vehicle, through which the vehicle’s driver can see the road; but
does not include a coating added after manufacture of the material.
luminous transmittance, for glazing or a coating on glazing, means the amount of light that can pass through the glazing as a percentage of the amount of light that would be transmitted if the glazing or coating were absent.rear glazing, for a heavy motor vehicle, means glazing used in a window or interior partition of the heavy motor vehicle located behind the driver in the normal driving position. sch 2 s 21 amd 2015 SL No. 188 s 33; 2017 SL No. 113 s 24
