My interpretation says that any window from the C-pillar forward can be tinted no more than 30% under any circumstances.
The rear window can be tinted as dark as you want, provided that your car has a side mirror mounted on both the right and left front doors.
And I didn't have to type that all in...just a bit of cut n' paste. Formatting it so that it looked tidy was a beeeeotch, though.
