The law did NOT change from 25% to 35%.. it kept the 25%..
On top of that side windows to the rear are exempt now! Black them out!
The only thing this new law does is levy a $1k fine on installers who do not affix a statement that FRONT SIDE SUNSCREENING DEVICES(IE TINT) complies with the 25% rule.
So now Texans can enjoy 25% on the front and anything on the rear side and back window so long as you have 2 side mirrors! I'm waiting until September 1st now to get my tint!
