You might be surprised to learn that over 70% of Idaho drivers have window tints on their vehicles, but do you know if yours meet the state’s regulations? Idaho has specific laws governing window tint darkness and reflectivity, and failing to comply can result in fines and penalties.

As you’re cruising down the highway, you’re likely unaware of the nuances of Idaho’s window tinting laws, but it’s essential to understand them to avoid getting pulled over. What are the exact rules, and how can you certify your vehicle is compliant?

Idaho Window Tinting Laws

Idaho Window Tint Laws Overview

Since 1992, Idaho has been enforcing window tint laws that apply to all privately owned autos registered in the state, regardless of type or size.

As you consider getting your vehicle tinted, you should know that Idaho window tint laws in Idaho prioritize Visible Light Transmission (VLT) and window tint reflection.

For your front side windows, you’re allowed non-reflective tint above the AS-1 line or top 6 inches of the windshield.

Rear side windows have fewer restrictions.

Medical exemptions are also available, but you’ll need to follow Idaho window tinting regulations.

Window Tint Darkness Regulations

Frequently, drivers in Idaho wonder about the acceptable levels of window tint darkness.

Idaho window tint rules specify that your front side windows must allow more than 35% of light in, measured by the Visible Light Transmission (VLT) percentage.

The rear side windows can have a tint rated as dark as 20% VLT.

The windshield can have non-reflective tint applied above the AS-1 line or top 6 inches, and medical exemptions allow for tint as dark as 20% VLT on front side windows.

The rear windshield can be tinted down to 35% VLT, but you’ll need dual side mirrors.

Window Tint Reflection Rules

Beyond the darkness regulations, Idaho’s window tinting laws also dictate the acceptable levels of window tint reflection.

You’ll need to guarantee that your window tint doesn’t exceed the allowed reflectivity levels.

  1. The front side windows can’t have a reflective material with a reflectance of more than 35 percent.
  2. The side windows to the rear of the driver can’t have a reflective material with a reflectance of more than 35 percent.
  3. There’s no specified reflectance limit for the rear window, but it must allow at least 5 percent light transmission.

Medical Exemptions and Special Cases

If you have a medical condition that requires darker window tint, you may be eligible for a medical exemption.

This exemption allows you to install window tint with a lower visible light transmission (VLT) percentage than normally permitted, such as 20% VLT on front side windows or even 75% VLT on the windshield itself.

To qualify, you’ll need to provide documentation from a licensed physician explaining the medical necessity for darker window tint, which is often related to skin or eye health issues.

Medical Exemptions

Your doctor’s note can be your ticket to darker window tints, even in states with strict laws.

In Idaho, medical exemptions are permitted for individuals who require special tint due to medical conditions. This means you can enjoy the benefits of darker window tints while still complying with Idaho state regulations pertaining to window tinting laws.

Idaho allows medical exemptions for certain conditions, such as photosensitivity or lupus.

You’ll need to obtain a doctor’s note explaining your condition and the required tint percentage.

Variance: State laws allow for exemptions for special tint, so be sure to review Idaho’s specific regulations.

Skin Health Issues

You may be surprised to learn that certain skin health issues can qualify you for a medical exemption from Idaho’s window tinting laws. If you have a condition that makes you extremely sensitive to light, such as albinism or porphyria, you may be eligible for a special window tinting permit. This permit allows you to install window film with a lower percentage of light allowed, reducing glare and reflection.

LupusReduce UV exposureWindow tint with high UV protection percentage

Eye Health Conditions

Certain eye health conditions can also qualify you for a medical exemption from Idaho’s window tinting laws, much like skin health issues.

If you have a condition that makes you sensitive to light, you may need a darker tint to reduce glare and discomfort.

  1. You have a condition that makes you sensitive to light, such as photophobia, and need a darker tint to reduce glare and discomfort.
  2. You experience severe eye strain or headaches from window reflection when using a lighter tint, and a darker tint would alleviate these symptoms.
  3. You have a condition that requires you to reduce glare and reflect incoming light, and a darker, non-reflective tint is allowed under Idaho’s window tint law, which permits a higher Visible Light Transmission (VLT) percentage for medical exemptions.

Idaho Window Tint Installation Guidelines

Idaho’s window tint installation guidelines provide specific regulations for motorists who want to tint their windows.

In terms of your windshield, you can apply tint above the AS-1 line or top 6 inches, but it must be non-reflective.

For your front side vents, the window tint VLT must allow more than 35% of light in, with a maximum reflectivity rating of 35%.

Rear side windows can have tint rated as dark as 20% VLT, with a 35% reflectivity rating, but you’ll need dual side mirrors if the back window is tinted.

In regards to certification, there’s a three percent variance allowed in Idaho, and installers don’t need to certify the window tint they install.

Idaho Tint Law Enforcement and Penalties

Window tint violations in Idaho are taken seriously, with law enforcement actively enforcing regulations to guarantee motorists comply with the state’s window tint laws.

Failing to comply with these laws can result in fines and penalties.

  1. Window tint violations are treated as traffic infractions, with fines and potential requirements to remove the tint.
  2. Idaho law enforcement actively enforces window tint regulations, with the Idaho State Police empowered to promulgate rules and implement the laws.
  3. You’re allowed a three percent variance in window tint VLT, providing some flexibility in enforcement and measurement.
