Australian Auto Tinting Laws
All States and Territories in Australia stipulate a maximum darkness, known as the visible light transmission level or VLT, of 35% on all vehicle windows (excluding the front windscreen, which cannot have any window film, except for a visor strip across the top). The only exceptions are NT, which allows a minimum VLT of 16% for windows behind the driver; and WA, which allows 20% VLT on windows behind the driver.
Automotive films supplied by WFAANZ member manufacturers are low reflectivity, as the law states window film on vehicles must not be reflective. Reflective films are even more dangerous than illegally dark windows. All Police Forces and Transport Departments are very vigilant on defecting vehicles with reflective films. Reflective films are the shiny silver and bronze films, which can be “fader” films changing from dark to reflective, solid reflective films or sometimes shapes such as flames or similar.
Commercial vehicle tinting laws differ in most States and Territories - so ensure you know the rules before you tint a commercial vehicle. Typically, any darkness film is allowed behind the driver in commercial vehicles. ‘Commercial vehicles’ do not mean 4WDs, but rather vehicles registered as a commercial type.
WFAANZ is dedicated to ensuring compliance of our members with government regulations. Failure to comply with tinting laws can result in fines, insurance cancellation and even criminal charges if a vehicle is involved in an accident and its illegally dark windows are considered a contributing factor - so you are doing your client a disservice if you fit their car with illegal film.
Remember, modifying a vehicle with illegally dark windows renders that vehicle unroadworthy.
