Yes it is legal to have mirror tint, but there is a limit on how much it mirrors, if that makes sense.

Most cars you see on the road that have mirror tint do not meet the standard as they are too reflective.

i think the mirror limit is 10% reflective

if i were to get the bottom quaters of my side windows in mirror tint, so it looks blue almost, and on an angle starting 2" up at the front and moving 6" up to the back, does anyone know if that would be leagal, because its not a constant tint pattern?
cheers
