Born and raised in Iowa.....1998 joined the Air Force and i have been gone since then. Well, the last 20 years has been amazing, but it may be time to call it a day after 20 years serving this great country. The wife and I plan on moving back to Iowa, yes, sounds crazy, but we have lived all over the country but we want the 4 seasons and the slow simple life that Iowa offers. Now to my question, how strict are the tint laws nowadays? All three of my vehicles are heavily tinted and I am wondering how much of a pain it may be. My car is very dark, my truck needs the tint redone after 16 years of the same tint, and my wife's Jeep has no tint on the driver/passenger window. Right now we live in Texas, and will be for the next 18 months, just wondering how the laws are nowadays.

Thank You!!!

From what a tint shop told me in Cedar Rapids, when I lived there, the law says no less than 70% light transmittance in the front door windows, no more than factory tint on the windshield, and no restrictions in the back door (or quarter windows) and rear window.

Enforcement varies by jurisdiction, in any event, anything darker than the above always provides a reason for an officer to pull you over if he suspects something else. Cedar Rapids tended not to worry so much about it, but Marion was real strict on it, so best just to abide by the law.

Thank you for your service from someone who still stands for the National Anthem!
