There are specific laws regarding car window tinting in Australia. These refer to the darkness of the film used on windows or, more specifically, the visible light transmission or VLT of the film you apply. These laws were implemented because window film used in car windows may lead to theft and even accidents. Regulations and limits have been formulated and imposed because of the following reasons:
- Most car owners believe that the darkest shades of window film cut out more light and reduce heat inside the car, which isn’t always true. This is because the quality of the film determines the level of heat rejection, not its depth. Moreover, the manufacturing process and material also affect the amount of light and heat a window film successfully keeps out.
- A light, vehicular window tint, which is metal-based, rejects a far greater amount of heat than any dark product that is dye based. The UV ray rejection factor also doesn’t depend on film darkness in all cases. Undoubtedly, darker film cuts out more light, but inevitably, results in poor vision from behind the glass while driving at night. This may obviously lead to accidents or other mishaps.
- In addition, the authorities may impound your vehicle and removal of the film would be required. Moreover, your vehicle may fail to pass registration during inspection.
- The most important factor to consider is that if state regulations are not followed when it comes to applying window film, the vehicle’s motor insurance will be declared null and void. Also, should an accident occur due to incorrect window tinting, the vehicle’s owner exposes himself to further prosecution and dire consequences as per laws.
All Australian states stipulate a VLT limit of 35 per cent for front and passenger windows. This means that a minimum of 35 per cent light must be able to pass through the window glass after installing the film.
