21 Window tinting
(1) Glazing used in a windscreen of a heavy motor vehicle must have a luminous transmittance of at least 70%.
(2) Glazing used in a windscreen of a heavy motor vehicle must not be coated in a way that reduces its luminous transmittance.
(3) However, subsections (1) and (2) do not apply to the greater of the following areas of a windscreen—
(a) the area above the highest point of the windscreen that is swept by a windscreen wiper;
(b) the upper 10% of the windscreen.
(4) Glazing used in a window or interior partition of a heavy motor vehicle must have a luminous transmittance of at least 70%.
(5) Glazing used in a window or interior partition of a heavy motor vehicle, other than rear glazing, may be coated to achieve a luminous transmittance of not less than 35%.
(5A) A heavy motor vehicle’s rear glazing may be coated to achieve a luminous transmittance of 0% or more.
(6) The requirements about luminous transmittance applying to glazing used in a window of a heavy motor vehicle stated in a second edition ADR or third edition ADR do not apply to a window that has been coated as provided in subsection (5) or (5A).
(7) Glazing used in a windscreen, window or interior partition of a heavy motor vehicle that has been coated to reduce its luminous transmittance must not have a reflectance of more than 10%.
(8) In this section—
glazing—
(a) 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
(b) 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.
