That sounds about right. I had mine done this past spring at 35% too. Although it isn't legal in Illinois, something about SUVs with factory tints in the rear, can only do 50%. There's a picture in my gallery with a side view of my MO where you can get an idea how it looks. Also, an earlier one, same view, before I had the tinting done. Hope this helps and take care!

I made the huge mistake of tinting the windows last week (wanted it even darker than the factory stained OEM glass) at 4% tint. Its all but impossible to see out the windows at night, because of the compounding factor of the tint and darkened glass.

Even during the day, it's a nuisance and not worth it. Will definitely have to get the job redone, especially now taht I realize my hatch is only getting 1% light through...(.25X.04).
Dan, thanks for one of the most thoughtful posts I've read on the topic of glass tinting.

The thing some folks tend to forget is that your LIFE depends on being able to see out those windows - all of them.

Every state has different laws regarding the acceptable amount of tint on windows. Excessively dark windows are dangerous to you and also make law enforcement people nervous if they ever approach the vehicle. Both are huge negatives.

I researched this once and found a helpful site: Auto Window Tint Laws | TintCenter Window Tinting

Some states have no limitations, but most do. It's a good idea to adhere to them and not to exceed the legal limits for light reduction.

Congratulations on realizing that your eyes are telling you something important! :4:

Wow, I knew that the windshield was tinted, but not so much that you could block 21% of the light! Also good to know that 100% of UV radiation is blocked by the windshield and a few other passes through the glass.

Cool. How's this? I also corrected some errors in the previous post (got some digits in the wrong place for thickness and Tv).

Sorry I have to ask what is Visible Ray Transmittance mean exactly?

Also what is the percentage that the front door glass is tinted at? My front windshield was replaced with an aftermarket one it very clear that it doesn't look anything like the factory one; its so clear that during sunny days my MO gets fairly hot from the sun beating in the windshield while the back which is tinted stays a bit cooler. I would like get my windshield tinted close to what my front door windows are, anything darker would be silly I think. as my front doors are lighter than my back, side windows, and rear hatch window.

Thanks
A.

Just look at the chart, the windsheild is tinted at 79% and the front windows are at 74%. Although i would let the tint shop correctly match them as materials have different properties and colors between brands.

Does anyone know if photochromatic lenses (glasses that turn dark in the sun) work with 100% UV blockage? I would hate to be driving in the sun and they don't turn dark! That's what they always tell me when I buy new prescription glasses....they won't work inside a car.

Photochromic lenses will not darken in a car (with all windows up) because they react to the UV light that is so effectively blocked by auto glass. I know, I keep a pair in the car.

The reason that the windshield is 100% blocking the UV is because it is laminated glass. The plastic interlayer stops all the UV which manages to pass through the glass.

Even clear window glass will stop most UV. It is just the nature of normal glass to not transmit UV very well. Fused silica glass transmits nearly 100% of the UV, but is never found in windows outside of laboratory settings because it is very difficult to manufacture.

This is right, I have to wear clip on sunglasses over my Transitions lenses when I'm driving.

My co-worker just told me that he got a new prescription and he told me there is a new product (and he has it) that transition while inside the car.

I also wear glasses but my transition NEVER turns dark when I'm inside the car.

BTW, I'm about to purchase a pre-cut windshield tint.. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370593415698#ht_6556wt_907

Anybody here has a recommended other brand?

TIA

I just got a traffic violation for having 12% tint on my 2 front windows. I didn't even know they were 12%. I told the guy to match up the front windows with the back ones. But I had forgotten he had already put a layer of 35% on the back windows which were already dark from factory.

Sorry to hear that. It's a reminder that staying within state law is a very good idea, and looking up the numbers online before installation is also a good idea.

I know but it was daytime and the the sun was out. I didnt think they would stop me for that. I once got stopped at 4am and I was drunk as a fish and I got stopped. the cop asked me "do you know why I stopped you?" I said cuz my music was too loud? he said "yes your right, license and registration" I said no problem Im gonna get a ticket for noise pollution and I wont have to take a breathalizer. 35 minutes later he comes back and gives me a ticket for my 2 front windows being too dark(he never measured how dark they were) and for noise pollution. I said "thank you Baby Jesus" Never again I go clubbing, drinking and driving. Now I carpool to places.

Dang! Sounds like it was actually both a beneficial experience, and cheap at the price. Congrats on learning from it.

So rear factory tint is 18%-20% or so?

Fronts can use a 35% and still be legal within most states and provinces? Nice.

In Canada and I wouldn't be surprised if the law is the same your windows can't be darkened or tinted, and the police must be able to see into your vehicle not matter is what time of day or night it is. Just be thankful you don't live in Colombia because you aren't allowed to tint your windshield if you do you were given a warning first, the second time the police smash your windshield in. :)

In Ontario and Quebec;

Window tinting is addressed in sections 73 and 74 of the (Highway Traffic Act) whereby the surface of the windshield or any side window to the left or right of the driver cannot be coated with any colour spray or other colour coating in such a manner as to obstruct the driver's view of the roadway, or obscure the view from outside to the interior of the motor vehicle; Translation: you have to be able to see outside, and other people, especially police, have to be able to see you.

If they decide they can't see you, you could be fined anywhere from $85, plus surcharges and fees, to $500.

In British Columbia, Alberta, Saskatchewan and Nova Scotia, it's illegal to have any tint at all on driver and passenger side windows.

"A lot of people are surprised to find that out," says Calgary Police traffic section Staff Sgt. Paul Stacey. "Shops here aren't supposed to do the front side windows but some still do."

Likely if you look at the laws in the States they are probably similar to the Canadian ones when it comes to window tinting.

As for the police, and other emergency vehicles being tinted, well there is a law that exempts them from the tinting law. Just like there is law that exempts them from the driving while talking on your cell phone. :)

Lol whassup guys. Haven't been on here for a while. But just an update. I've gotten stopped dozens of times by now and never been ticketed or summoned. I haven't taken off the tints. Tints are still the same. I now work for the city of NY as a public transportation bus driver. Every time I get stopped I show my work ID and they let me go. One cop stopped me once and told me "oh ok nevermind I'm not gonna give you a bull**** ticket, have a good night" I was like :30: ok thank you. Lol
