Ever wondered why some cars on Missouri’s roads appear darker than others?

It’s all about “Missouri Tint Laws,” legislations enacted in 2002 to govern the tinting of vehicle windows.

If you’re considering adding some tint to your car windows, it’s crucial to familiarize yourself with these laws.

Regulations Regarding Window Tint in Missouri

The state of Missouri has detailed guidelines regarding the permissible tint of darkness and reflectivity.

These rules vary based on the type of vehicle (sedan, SUV, or van) and the specific window.

Car WindowsAllowed Tint DarknessAllowed Tint Reflection
WindshieldNon-reflective tint above manufacturer’s AS-1 lineNot specified
Front Side WindowsMust allow over 35% of light inMust not be more than 35% reflective
Back Side WindowsAny tint of darkness can be usedMust not be more than 35% reflective
Rear WindowAny tint of darkness can be usedNot specified


In Missouri, the law permits non-reflective tints above the manufacturer’s AS-1 line on the windshield.

This is to ensure enough visibility for the driver while protecting them from excessive sunlight.

Front Side Windows

Regardless of your vehicle type, front side windows must allow over 35% of light in.

This rule aligns with the Visible Light Transmission (VLT) measure, ensuring safe visibility levels for drivers.

Back Side Windows

Missouri law is more lenient for the back-side windows.

It allows any level of darkness, provided the vehicle has dual side mirrors for adequate visibility.

Rear Window

Similar to the back side windows, there’s no restriction on tint darkness for the rear window. This rule holds as long as your vehicle has dual-side mirrors.

Additional Regulations

Apart from window-specific guidelines, Missouri has further regulations covering tint color, reflection, medical exemptions, and penalties for non-compliance.


When it comes to tint reflection, Missouri aims to minimize glare and heat.

For both sedans and SUVs or vans, front and back side windows must not be over 35% reflective.

This reduces the chances of reflective glare affecting other drivers.

Medical Exemptions

Missouri also has provisions for medical exemptions.

If you have a medical condition requiring special tint, you can apply for an exemption.

Always check with local authorities to understand the procedure.

Color Restrictions

Interestingly, Missouri law does not explicitly ban any colors of tint.

However, it’s advisable to avoid colors that might interfere with law enforcement or be mistaken for emergency vehicles.

Side Mirrors

If back windows are tinted, the vehicle must have dual-side mirrors.

This ensures visibility and safety on the roads.

Exceptions to Legal Limits

For vehicles registered in other states but driven in Missouri, the law is accommodating.

It recognizes the validity of the tinting laws of the vehicle’s home state.

Penalties for Breaking the Law

Ignoring Missouri’s tint laws can lead to consequences. Fines and other penalties are designed to ensure compliance.


First Conviction

A first-time violation might seem like a small infraction. However, fines can be hefty, with penalties starting at $100.

Second Conviction

Repeat offenders face stricter penalties. The fine for a second offense can be as high as $200.

Third Conviction

Consistent violators pay the most. The third and subsequent convictions can lead to fines up to $250.

Other Penalties

Apart from fines, non-compliance can also result in points added to your driving record, which may impact your insurance rates. It’s always better to adhere to the law and avoid these complications.

Penalties for Non-Compliance

Non-compliance with Missouri tint laws could lead to more than just fines.

Penalties can also include mandatory removal of the non-compliant tint at your own expense and even possible vehicle impoundment in extreme cases.

In essence, understanding and adhering to the “Missouri Tint Laws” can save you from legal troubles, monetary penalties, and potential hazards on the road.

It’s not just about the aesthetics of your vehicle, but more importantly, your safety and the safety of others on Missouri’s roads.
