Chile’s recently passed law (as of March, 2019) permitting the unconditional application of aftermarket tinted windows on cars is already being debated in congress.
Previous legislation permitted tinted windows installed by automakers, the new and less restrictive law are subject to regulation, with some local lawmakers claiming that darker shades could hinder the enforcement of traffic infractions and crime investigations such as the authorities’ ability to enforce laws such as seatbelt usage and child safety seat usage.
One solution could be to follow the international standard which is allowing at least 18% transparency in the rear windows and 45% in the front windows.
In Ireland, motorists must meet a requirement of not less than 65% light transmission. There is no limit on the tint level in the rear window and rear side windows.
