Anything forward of the B pillar (front windows) must not be tinted in any way.
You are however still allowed to perform any level of tinting on your rear windows.
This new legislation came info effect in January 2004, However it has been applied retrospectively and so if you’ve tinted your windows before January that does not mean that you are safe, if the police believe that your tint causes reduced visibility they can issue you with an order to have it removed.
