During the last 3-4 years the Glass and Glazing Federation (GGF) and other leading window film manufacturers have been putting forward their views, to obtain a clear definition on the law of window tinting. However, as of January 2004 the government has rewritten the law to incorporate a tint level of seventy percent visible light transmission on the front driver and passenger side windows. Vehicles 10 years and older already have this level of tint is manufactured within the glass from the vehicle manufacturers. This means that if any window tinting company or manufacturer installs films to the front driver or passenger side windows or front quarter windows, they are in infringement of the law.
