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 relecting sunlight or headlight beams.
