Window Tinting in Missouri: Following the Laws and Maintaining Privacy

Window tinting is a popular modification for vehicles, offering benefits such as reduced glare, increased privacy, and protection from harmful UV rays. However, tinting windows also comes with specific legal restrictions to ensure safety on the road. Missouri, like many states, has established laws regulating the level of tint allowed on vehicle windows. Understanding these laws is crucial for vehicle owners to avoid legal penalties and ensure compliance.

Legal Framework for Window Tinting in Missouri

Missouri's window tinting laws are codified in the Missouri Revised Statutes, specifically under Section 307.173. These laws outline the permissible levels of tint for different types of windows on a vehicle. Here are the key points:

  1. Front Side Windows: The law requires that front side windows allow more than 35% of light to pass through (VLT – Visible Light Transmission). This means that the tint must not reduce the light transmission below 35%.

  2. Rear Side Windows: Missouri law is more lenient for rear side windows, allowing any darkness of tint. Vehicle owners have more flexibility in choosing the level of tint for these windows.

  3. Rear Window: Similar to rear side windows, the rear window can have any level of tint darkness. However, if the rear window is tinted, the vehicle must have dual side mirrors.

  4. Windshield: Tinting is restricted to the top portion of the windshield. Missouri law permits a non-reflective tint on the top 15 inches of the windshield. This is commonly referred to as the "AS-1 line," which is usually marked on the windshield.

  5. Reflectivity: The law also regulates the reflectivity of the tint. Reflective or mirrored tints can create glare and impair visibility for other drivers. Missouri restricts the reflectivity of window tint to not exceed 35% reflectivity.

  6. Medical Exemptions: Missouri allows exemptions for medical reasons. If a driver has a medical condition that requires lower light transmission, they can apply for an exemption with appropriate documentation from a physician.

Factors to Consider When Getting Windows Tinted

  1. Compliance with the Law

    • Understanding Legal Limits: Familiarize yourself with Missouri's window tinting laws to ensure compliance. Violating these laws can result in fines and the need to remove the non-compliant tint.

    • Medical Exemptions: If you require a darker tint for medical reasons, obtain the necessary documentation and apply for an exemption. This will protect you from potential legal issues.

  2. Type of Tint

    • Dyed Window Tint: This is the most affordable type of tint and offers a darker appearance. However, it may not be as effective at blocking heat and UV rays compared to other types.

    • Metalized Window Tint: This type of tint contains tiny metallic particles that reflect heat and UV rays. It is more durable but can interfere with electronic signals.

    • Carbon Window Tint: Carbon tint provides excellent UV protection and does not interfere with electronic signals. It is more expensive than dyed tint but offers better performance.

    • Ceramic Window Tint: This is the highest-quality tint available, offering superior heat and UV protection without any interference with electronic signals. It is the most expensive option but provides the best overall performance.

  3. Benefits of Window Tinting

    • Heat Reduction: Tinting can significantly reduce the amount of heat entering your vehicle, making it more comfortable to drive in hot weather.

    • UV Protection: Window tint blocks harmful UV rays, protecting your skin and reducing the risk of skin cancer. It also helps prevent the interior of your car from fading and deteriorating.

    • Glare Reduction: Tinting reduces glare from the sun and headlights, improving visibility and reducing eye strain.

    • Privacy and Security: Tinted windows offer increased privacy by making it harder for others to see inside your vehicle. This can also deter potential thieves.

  4. Quality of Installation

    • Professional Installation: Choose a reputable professional for installing window tint. Proper installation is crucial for ensuring the tint's effectiveness and longevity.

    • Warranty: Look for installers who offer a warranty on their work. This can provide peace of mind and protection against defects or issues with the tint.

Deciding How Much Tint to Apply

  1. Legal Limits

    • Adhering to Legal Standards: Ensure that the tint level complies with Missouri's laws. For front side windows, choose a tint that allows more than 35% of light to pass through.

    • Personal Preference: For rear side windows and the rear window, you have more flexibility. Decide on the level of darkness based on your personal preference and desired level of privacy.

  2. Purpose of Tinting

    • Climate Considerations: If you live in a hot climate, you may want a darker tint to reduce heat and glare. Consider a high-performance tint like carbon or ceramic for the best results.

    • Daily Use: Think about how you use your vehicle. If you frequently drive at night or in low-light conditions, a very dark tint may not be practical and could reduce visibility.

    • Medical Needs: If you have a medical condition that requires lower light transmission, apply for a medical exemption and choose a tint that meets your needs while complying with the exemption requirements.

Where to Go for Professional Tinting Services

  1. Reputation and Reviews

    • Research: Look for reputable tinting service providers with positive reviews and ratings. Ask for recommendations from friends, family, or online communities.

    • Experience: Choose a provider with experience in installing window tint. Experienced installers are more likely to deliver high-quality work and avoid common issues.

  2. Certifications and Warranty

    • Certified Installers: Look for providers with certified installers. Certification ensures that the installer has received proper training and adheres to industry standards.

    • Warranty: Ensure that the provider offers a warranty on both the tint film and the installation. A good warranty can protect you against defects and provide peace of mind.

  3. Cost and Quality

    • Get Multiple Quotes: Obtain quotes from several providers to compare prices and services. While cost is an important factor, don't compromise on quality. Cheaper options may use lower-quality tint that doesn't perform as well or last as long.

    • Quality of Materials: Ask about the types of tint films used by the provider. High-quality films may be more expensive but offer better performance and durability.

Legal Penalties for Non-Compliance

  1. Fines and Citations

    • Initial Offense: Violating Missouri's window tinting laws can result in fines of up to $75 for the first offense. The exact amount may vary depending on the jurisdiction.

    • Subsequent Offenses: Repeat offenders may face higher fines and additional penalties. Law enforcement officers have the discretion to issue citations for non-compliant tint levels.

  2. Correction Orders

    • Removal of Tint: In addition to fines, you may be required to remove the non-compliant tint and replace it with a legal tint. Failure to comply with correction orders can result in further penalties.

    • Inspection and Proof: You may need to provide proof of correction to law enforcement or undergo an inspection to verify compliance with the law.

  3. Impact on Vehicle Inspections

    • Vehicle Inspections: Missouri requires periodic vehicle inspections to ensure compliance with safety and emissions standards. Non-compliant window tint can result in a failed inspection, preventing you from legally registering your vehicle.

  4. Insurance Implications

    • Insurance Coverage: Non-compliant window tint may affect your insurance coverage. Some insurance policies may have clauses that void coverage in the event of an accident if the vehicle is found to be non-compliant with state laws.

    • Claims and Liability: In the event of an accident, non-compliant window tint could be used against you in insurance claims or legal proceedings, potentially increasing your liability.

Conclusion

Understanding and complying with Missouri's window tinting laws is essential for vehicle owners who wish to enjoy the benefits of tinted windows while avoiding legal penalties. By considering factors such as legal limits, types of tint, benefits, and quality of installation, you can make informed decisions about window tinting for your vehicle. Additionally, choosing a reputable provider and adhering to the law can help you avoid fines, citations, and other penalties associated with non-compliant window tint.
