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.
