Give it a share!

The degree to which a driver can legally tint their car’s windows vary from state to state. To make it just a little easier for drivers, we’ve got all the laws here in one place.

If you’re looking to get your car windows tinted (or even tinting them yourself), you might want to double check the window tinting laws in your state. As with many regulations, window tinting laws vary state by state and can be nuanced and hard to understand. This may not be a problem if your car has never and will never leave the state, but it can get complicated for those who travel a lot, purchase out-of-state vehicles or move around the country. If that’s you, you’ve come to the right place.

We’ve consolidated all the information you need to know to make sure your cool tinted windows are legal.


These are the terms you need to know in order to interpret the various state laws and limits.

VLT%: Visible light transmission is the measurement used to assess automotive window tints. This is the percent of visible light that gets through either the film (film VLT%) or window plus film net VLT%. The lower the VLT%, the darker the tint.

Front-side window tint level: This is the amount of tint (VLT%) you’re allowed on your driver and front passenger windows. This is frequently a higher value than for the rear, which allows the driver of the vehicle to be seen from outside.

Rear-side window tint level: This is the amount of tint (VLT%) you’re allowed on your rear side windows. This value is sometimes different for passenger cars and multi-purpose vehicles (MPVs).

Rear window tint level: This is the amount of tint (VLT%) you’re allowed on your rear window. This value is typically the same as for the rear side windows, but some states are more restrictive.

Windshield: Your windshield cannot be tinted in any state, but some states allow you to add a sticker to the top of the windshield, usually in the area of the manufacturer’s sun shield.

Color: The state laws on tint color vary from no restrictions at all to restrictions on the use of certain colors or reflective/mirrored finishes.

AS-1 Line: This is the line extending from the letters AS-1, found on most motor vehicle windshields, running parallel to the top of the windshield.

Even if most of the laws for state window tint are straightforward, some use slightly ambiguous terms that leave some room for law enforcement and licensing agencies to interpret.

Use your best discretion but it may be best to stay on the safe side to avoid headaches in the future.
