Understanding Colorado Tint Laws: What You Need to Know


Window tinting can be a great way to enhance the aesthetics of your vehicle and protect yourself from harmful UV rays. However, it’s important to be aware of the laws and regulations regarding window tinting in your state. In Colorado, there are specific rules that govern the darkness and reflectivity of window tints. Understanding these laws will help you ensure that you are in compliance and avoid any potential legal issues.

Darkness Limits

When it comes to window tint darkness, Colorado has set specific limits for each window of a vehicle. The front windshield must allow in at least 70% of light, while the front side windows must allow in at least 27% of light. The rear side windows and the rear windshield can have any darkness level, but if the front side windows are tinted, the rear side windows and rear windshield must have a minimum of 27% light transmission.

It’s important to note that these limits refer to the amount of light that must be allowed to pass through the window tint. This means that the darkness of the tint itself may be higher than the specified limits, as long as it still allows the required amount of light to pass through.


In addition to darkness limits, Colorado also has regulations regarding the reflectivity of window tints. The front side windows and the front windshield must have a reflectivity of no more than 20%. This means that the tint should not be highly reflective, as it can interfere with the visibility of other drivers on the road.

Medical Exemptions

Colorado allows for medical exemptions to the window tint laws. If you have a medical condition that requires you to limit your exposure to sunlight, you can apply for a medical exemption. To qualify, you will need to provide documentation from a healthcare professional stating the specific medical condition and the need for tinted windows. If approved, you will be issued a medical exemption certificate, which you must carry in your vehicle at all times.

Enforcement and Penalties

Law enforcement officers in Colorado are vigilant about enforcing the window tint laws. If you are found to be in violation of the tint laws, you may be issued a citation and required to remove or modify the tint to comply with the regulations. The penalties for non-compliance can vary, but they can include fines and even the suspension of your vehicle registration.

It’s important to note that ignorance of the law is not a valid defense if you are pulled over for a tint violation. It is your responsibility as a vehicle owner to ensure that your window tints are within the legal limits.


Understanding the window tint laws in Colorado is crucial if you want to avoid any legal issues and ensure your safety on the road. By adhering to the darkness and reflectivity limits, and by obtaining a medical exemption if necessary, you can enjoy the benefits of window tinting while staying within the boundaries of the law.

Remember to always consult the official Colorado Department of Revenue website or contact your local law enforcement agency for the most up-to-date and accurate information regarding window tint laws in your area.
