What is the maximum window tinting allowed?

[derik]

There are so many versions I heard here that I am literally confused now and need some help guys.

• 30% allowed but up to 50% acceptable (no fines)
• Up to 30% allowed only
• Driver (30%), rear passenger window and back glass can be anything
• Front (30%), rear (50%) and back glass (boot) 30%

Second doubt is, does the high end tinting films block the GPS and Mobile signals....?

Does the front clear screen of high end brand like 3M crystalline block the GPS signals....?

Man keep it 30% and you will be safe, don't listen to rule-breakers.

For second question I am also curious to know the answer.
