since i've seen a lot of posts & tinting law for individual states i thought of posting one site that shows every state

http://www.tintcenter.com/laws/

it also has on the right bottom corner a neat table with some basic FAQ
Window Film FAQ (i didn't know much about tinting b4 this research - am planning to get them tinted this summer)

also i found this for those who encounter picky cops:


Recently the police department has noticed a excessive number of vehicles on the road with illegally tinted windows, and with illegally colored lights mounted on the front and sides. Both of these violations subject the vehicle operator to a moving vehicle traffic citation, with a $40-50 fine assessed.

1) TINTED WINDOWS -The 35% Window Tint Law in Maryland means that the TOTAL amount of light being transmitted through the glass of a motor vehicle cannot be less than 35%. In other words, it doesn't make any difference what percentage
the actual window tinting film is rated at, you still cannot exceed 35% total Light Transmittance Value, or LTV for short.

The problem here is that many people purchase a window tint film that is rated at 35% and think it's automatically okay to put it on their car windows. A 35% window film will guarantee you that your vehicle will be illegal, and here's why:

ALL vehicles come from the factory with a certain percentage of tinting incorporated into the glass. In most cases it blocks out approximately 20% of the available light, which means that 80% is still passing through.
That is an LTV of 80%, and there's no problem there.

An after market window tint film rated at 35% means that the film allows 35% of the available light to pass through, and blocks out 65%. (This is known as 35% LTV Film) And again, there's no problem with that.

Here's where the trouble begins. When you place a 35% window tint film over a vehicle window that is already blocking out 20% of the available light, you have now reduced the LTV to 28%, which is ILLEGAL! Why is it now 28%? Because you
started with a piece of glass that was already blocking out 20% of the available light, and you are now placing a 35% tinting material on a piece of glass that only had 80% available light to start with. (.35 x 80 = 28%)
That means you are now blocking out 72% of the available light, leaving only 28% to pass through.

I hope this helps clarify some points
I do have a question though...does anyone know where i can find out if our tC's already have some base standard tint on them?

 

can you have 20 in the back and 35 upfront?

 

..?

great tnx for replyin to him then

 

Italy, from what I know our windows do not have a factory tint. I have mine tinted 20% in front and 5% in back and back sids. I have not been stopped (knock on wood) and I highly doubt I will, unless im a dick to cops. The legal limit here is 35%. This was too light for me, let in too much sunlight and made my car hotter than it already gets...

 

you can do whatever you want. its just luck if you get caught for it. im gonna do 30-35 all around. great website. thanks

 

smith - u say 35% was too light for u how did u know...? as in do they show u examples in person of how they would look like at the shop? or u saw on the streets?
(knockin on wood for u BTW loving how u called me italy )

 

Italy, I had 35%, and the guy that does my tint gives me good deals so I changed the front to 20%. Since our interior is black and I live in the desert it get extremely hot, so hot my stereo wasn't working the other day. But cops here dont care too much about tint. 35% is alright but I felt it still let in too much light. I love the way my tint is set up now.

 

Yeah, I can guarantee that if I got a tint job like 06smith, I'd get fined. I go through Doraville very often (those in ATL know what I'm talkin' 'bout), those pigs 'll be on you in a hot minute. and I definately don't wanna' get caught in Cobb county...

 

so since my state has the same 35% law as yrs im guessing i wouldn't be bit*ed out either... id like to see the diff. between 35, 30, 25, and 20 on a tC

 

np my pleasure
