What's the darkest legal window tint?

[87LX2.3]

I want to put window tint on my Mustang. I think tinted windows look really cool, but I don't want to get a ticket for having my windows too dark. Does anyone know what the darkest legal window tint is in Iowa? Thanks!

Looks like 70% is the limit: Iowa State Patrol Division - FAQ Answers

Keep in mind most factory windows are already tinted 70%-80%.

Basically if the limit is 70%, that means no tint is legal for you.


They way it works, if the factory window is 75%, and you put 35% film on your window, the measured VLT will be about 26% on a meter.
