Motor Vehicles (Standards) Regulations - Australian Vehicle Standards Rules

(1) Glazing used in a windscreen of a motor vehicle must have a luminous transmittance of at least:

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

(3) However, subrules (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;

(4) Glazing used in a window or interior partition of a motor vehicle must have a luminous transmittance of at least 70%.

(5) Glazing behind the rear of the driver’s seat may be coated to achieve a luminous transmittance of not less than 35%.

(6) Glazing in a side window forward of the rear of the driver’s seat may be coated to achieve a luminous transmittance of not less than 70% or, if another law of this jurisdiction allows a lesser luminous transmittance, the greater of:

(a) the lesser luminous transmittance allowed under the other law; and

(7) Glazing that has been coated to reduce its luminous transmittance must not have a reflectance of over 10%.

(8) The luminous transmittance requirements in subrules (5) and (6) apply to a vehicle instead of the corresponding requirements in the relevant ADR.

glazing means material fitted to the front, sides, rear or interior of a vehicle, through which the driver can see the road, but does not include a coating added after manufacture of the material.

luminous transmittance, for 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 were absent.
