Tint applied to any side or rear window behind the driver’s seating position of a light passenger vehicle (vehicle with a gross vehicle mass not more than 4,500kg) must not have a light transmittance of less than 20% (T20) behind the driver’s seating position, provided there is a rear view mirror fitted to both sides of the vehicle. Tint applied to the windows in front of, or level to the driver’s seating position must not have a light transmittance of less than 35% (T35). This includes the combination of any applied tint and factory tinted glass.
A goods vehicle is allowed to have window tinting with 0% light transmittance, provided there is a rear view mirror fitted to both sides of the vehicle.
However, please be aware that the Australian Design Rules now allow privacy glass to be fitted rearwards of the driver’s vision. Privacy glass has no minimum light transmittance and is often darker than T35 tint.
Privacy glass incorporates tinted film within the glazing and does not involve an applied tint. All applied tint must meet the above requirements (for example, must not be darker than T20) and not the requirements set out for privacy glass in the Australian Design Rules.
Please note: Tinting may be fitted to the upper portion of a windscreen of a motor vehicle. The tinting must not extend lower than a horizontal line connecting the uppermost points of the arcs swept by the vehicle manufacturer’s original wiper blades or upper 10% of the windscreen, whichever is the lesser. The tinting may be of any shade but must not have a reflectance of more than 10%.
For the tinting requirements that apply to heavy vehicles (vehicles with a gross vehicle mass of more than 4,500kg), please contact the National Heavy Vehicle Regulator.

Is tinting my Taillights legal?
Often we have our customers ask us whether or not tinted tail lights comply with the Australian Design Rules (ADR). Below is information extracted from QLD Transport Operations (Road Use Management) Act 1995.
Disclaimer: This is by no means “legal” advice, but it may help you get out of a bind if a police officer issues a fine for such an offence. Please note that we are not road worthy assessors, compliance offices or the police; so this should be just considered as a guide only. We would suggest to get in contact with the appropriate authorities for clarification on the laws associated with this subject. Again; This information is provided simply for your interest, not as legal advice.
