Windshield Tint: The windshield tint laws are slightly different than other windows as Colorado state laws require a clear and unobstructed view of the road at all times. This means no obstructions hanging from your rear view mirror or in the dashboard that keep you from being able to fully see the road ahead of you. It also means you can’t have window tint on the windshield as it can make it harder to see road lines, signs, etc. The only tint allowed on the windshield is a strip that is no more than 4 inches tall across the very top of the windshield.
Front Side Window Tint: Window tint on front side windows must not be darker than 27% VLT. In vehicles that have the rear side windows or the rear window with a tint that is darker than 27%, the front side windows must not have any tint at all. This is why you never see semi-trucks and box trucks with window tint, as they cannot see out the back of their vehicles, so no tint is allowed on their front side windows due to safety concerns.
Back Side Window Tint: If the front side windows don’t have any tint at all, rear side windows may be as dark as you want. If the front side windows have a 27% or lighter VLT, then the rear side windows must also have 27% or lighter tint.
Rear Window Tint: The same goes for rear windows as rear side windows. If your front side windows don’t have any tint on them at all, then you are allowed to have your rear window as dark as you would like. However, if the front side windows have any tint, then the rear window must have a 27% or lighter VLT.
Window tinting has been around for decades because it can help keep sunlight out of the inside of the vehicle so that the interior temperature of the vehicle remains much cooler. It also keeps bright sun rays from warming up your legs and arms while driving and potentially giving you a sunburn. Many vehicle owners also choose to go with dark window tint because they simply like the look of it on their car and some choose it for privacy reasons. No matter what your reason for choosing to tint your windows is, make sure to keep your VLT values within the legal limits.
Penalties for having illegally dark window tint is a class B traffic infraction, so the penalties are usually just fines and maybe a few points on your license, but the real dangers come from not being able to see the road well which could lead to an accident an end up injuring yourself, your passengers or other people on the road. More on this below.
All vehicles in the United States come factory with a tint that is legal in all 50 states(if they come with window tint at all). So if your car only has factory window tint, then you know you are good to go, but if you or the previous vehicle owners had aftermarket window tint installed, you will need to check with your local police department, car dealership or buy a window tint tester. Some tint will come with a sticker or label showing what the VLT percentage is. If it does have this label, check to see if the numbers listed are within the 27% and 70% limits of Colorado law. Remember, if your VLT number is HIGHER than the legal limit, you are LEGAL. If your VLT number is LOWER than the legal limit, then you are NOT LEGAL.
