Car Tinting Law
Darkest Legal Tint
What are the rules?
Safe driving requires the driver to have the best possible vision of the road users. Any reduction in driver visibility particularly in poor light conditions will lead to a reduction in safety.
Tinted windows may reduce driver vision if not applied accordingly to state and territory regulations. Therefore it is desirable that the light transmittance of windows on a motor vehicle is not reduced below 35%*.
A tinted or opaque band across the top of the windscreen is permitted providing it is no lower than 10% of the height of the windscreen & is above the portion of the windscreen swept by the wipers. Tinted film must not be reflective or mirror-like as it can dazzle other drivers by reflecting sunlight or headlight beams.
In Victoria, VicRoads enforces a 30-35% VLT on all windows (this means 35% of light must come into your car through the glass) excluding the front windscreen which should not be tinted. Therefore, a window tinted below a VLT of 30% will render your vehicle unroadworthy.
If you choose 'Darkest Legal' (NANOTEK or BlackMax) for your vehicle the front windows will be lighter than the tinted glass at the back. Most people would like to colour match the glass on the front two doors, however this can certainly render your vehicle un-roadworthy. It has been a “grey area” for years and although the industry has lobbied government for many years, there is no resolution as yet. There is a ‘Petition” on the WFAA website that relates to this topic, please feel free to sign this.
Vehicles with factory-tinted glass
Most new vehicles are fitted with tinted window glass. This tint is very light and glass may at first appear to be clear. To check, hold a piece of white paper on the opposite side of the glass. If it has a slight gray, green or brown colour when viewed through the glass, then the glass is tinted.
Special grades of film may be applied to factory tinted windows. When these films are applied to tinted glass, the combination of tints must still allow 35% visual light transmittance**.
