Understanding Window Tint Laws in Maine: What Need to Know

Window tinting is a popular automotive customization that can offer several benefits, including reduced heat and glare, increased privacy, and protection of upholstery. However, it is important to comply with state regulations when it comes to window tinting. In this article, we will discuss the window tint laws in Maine and what drivers need to know to stay in compliance.

What are the window Tint Laws in Maine?

Maine has specific regulations when it comes to the percentage of visible light transmission (VLT) allowed on each window of a vehicle. For the front windshield, tinting is allowed only at the top of the windshield, and the tint cannot extend below the manufacturer’s AS-1 line. 

The AS-1 line is usually marked on the windshield and is a reference point for where the windshield wipers sweep. The tint on the top of the windshield must not extend more than 6 inches below the AS-1 line or down to the horizontal line at the top of the rear-view mirror, whichever is longer.

For the front side windows, tinting is allowed, but it must allow at least 35% of visible light to pass through. The rear side windows and rear windshield can be tinted to any degree, but they must still allow at least 35% of visible light to pass through.

Exemptions to Maine’s window tint laws are available for medical conditions, but drivers must have proper documentation from a licensed physician.

Types of Window Tinting Available:

There are different types of window tinting available, including:

Dyed window tint: A thin layer of dye is applied to the film to achieve the desired darkness. This type of tint is the most affordable but can fade over time.

Metallic window tint: Metal particles are embedded in the film to block heat and reduce glare. This type of tint is more durable than dyed tint but can interfere with electronic signals, such as GPS and cell phone reception.

Ceramic window tint: This type of tint is made of ceramic particles that block heat and reduce glare without interfering with electronic signals. It is the most expensive type of tint but also the most durable.

Penalties for Non-Compliance:

Drivers who violate Maine’s window tint laws can face fines of up to $250. Additionally, drivers may be required to remove the illegal tint and replace it with a compliant tint.

Ensuring Compliance with Maine’s Window Tint Laws:

To ensure compliance with Window Tint Laws in Maine, drivers should:

  • Have their vehicle’s tint measured by a professional to ensure it meets the state’s regulations.
  • Only use tint that is compliant with Maine’s laws.
  • Keep documentation of any medical exemptions in their vehicle.
  • Avoid using aftermarket films or adding tint to already tinted windows, which can increase the darkness beyond the legal limit.

Benefits of Window Tinting:

Window tinting can offer several benefits, including:

  • Reduced heat and glare: Tinted windows can block up to 99% of harmful UV rays, which can reduce heat and glare in the vehicle and protect the driver and passengers from sun damage.
  • Increased privacy: Tinted windows can provide increased privacy, making it more difficult for others to see inside the vehicle.
  • Protection of upholstery: Tinted windows can protect the interior of the vehicle, including upholstery, dashboard, and other surfaces, from fading and cracking due to sun exposure.

How to Choose a Reputable Window Tinting Professional

When choosing a window tinting professional in Maine, it’s essential to find a reputable and experienced provider. Here are some tips to help you select the right professional for your needs:

  1. Do your research: Start by doing research online to find potential window tinting providers in your area. Check their websites, social media pages, and reviews on sites like Yelp and Google.
  1. Read reviews: Reviews can give you valuable insights into the quality of work a provider offers. Look for reviews from customers who have had similar jobs done to yours.
  1. Consider experience: Check how long the company has been in business and how much experience they have in window tinting.
  1. Ask for references: Ask the provider for references from previous customers. Contact those references and ask about their experience with the company.
  1. Get multiple quotes: Get quotes from multiple providers and compare them. Don’t automatically go with the lowest price. Consider the quality of the work and the reputation of the provider.

Remember, the cheapest option may not always be the best choice. Look for a balance between quality workmanship and affordability.
