Indiana Window Tinting Laws: What You Need to Know

Many cars have window tint installed at the top of the windshield by the factory because it can help keep the sun out of a driver’s eyes and make driving safer, especially in the morning and evening.

For cars, trucks, SUVs, and vans, Window tint laws Indiana lay out certain guidelines to follow. According to state law, non-reflective window tint may be applied all the way down to the AS-1 line, which is indicated on the sides of the windshield glass with tiny letters. If there isn’t an AS-1 line visible on your car’s windshield, you should only apply a tint five inches below the top of the windshield.

Keep in mind that the only window tint that can be applied to a car’s windshield is non-reflective tint.

Windshield tint rules Indiana

Although there are many reasons why Indiana window tinting is a great idea, it’s ironic that the two main advantages of window film for cars are things that most people don’t even consider. Because UV light from the sun causes interior fading and cracking, window tint, which can block 99% of the light coming from the sun, helps protect the interior of your car and increase its resale value.

Second, window tint significantly lowers interior cabin heat by blocking most of the heat produced by the sun’s infrared light. This translates to a more comfortable car that uses less energy to cool, saving money on maintenance and putting less stress on the air conditioning system.

Even though most people associate window tint for cars with privacy and style, there are plenty of reasons to get window tint in Indiana, even if you’d prefer not to have your car’s appearance altered. These two benefits of window tint can be achieved with optically clear window film.

If you’re thinking about adding privacy and style to your windows and windshields, keep in mind that windshield tint rules Indiana dictate what kind of tint you can use and which windows you can apply it to.

Additional Indiana Window Tint Laws and Exemptions

When compared to laws in other states, the Indiana state window film law is quite lenient in many areas. For instance, Indiana does not have any prohibited window tint colors, and stickers indicating which tint is legal are not necessary to be applied.

Similar to other states, Indiana’s Window Film law does not specify where or how side view mirrors must be installed in order for window tint to be applied. Though any respectable tint vendor or installer will only offer such window film and you need only ask to confirm, the rules do require window tint manufacturers to certify window tint that will be sold and installed in Indiana as complying with the state’s laws.

You are able to install much darker window film on your car with a medical window tint exemption, which is permitted by the state. If you feel that your medical condition justifies a window tint exemption—from glaucoma to skin sensitivity to UV light—speak with your physician and ask for a dispensation that will allow you to use a darker tint. Additionally, always keep documentation in your car attesting to your medical exemption.
