(1)  Glazing used in a windscreen of a light motor vehicle must have a luminous transmittance of at least 70%.

(2)  Windscreen glazing of a light motor vehicle must not be coated in a way that reduces its luminous transmittance.

(3)  Subregulations (1) and (2) do not apply to the greater of the following areas of a windscreen:
