how rto approved sun control film can improve your driving experience

20 Feb 2025


Sun control films have become an important accessory for many vehicle owners in India, where there is extreme heat and glare throughout the year. These films serve two purposes: enhancing driver comfort and protecting passengers from harmful UV rays while maintaining compliance with legal standards. 

An RTO-approved sun control film for cars is designed to strike a balance between functionality and legality. They are an effective solution that reduces the discomfort that is caused by heat and glare while following legal guidelines set by the Indian Motor Vehicles Act. However, there are many misconceptions about sun films for cars, especially about their legality. Many vehicle owners think that all kinds of films are banned, so they don’t consider RTO-compliant options. 

In this blog, you will find out more about sun control film for cars and answer questions such as: why your car needs them, RTO rules, and which kind of films have been approved by them. So if you are having doubts, use this guide to clear all of them! 

Why Use Sun Control Film?


India’s tropical climate brings many challenges for drivers, particularly in urban settings where vehicles are exposed to a lot of intense sunlight. Excessive heat causes a lot of discomfort and affects driving focus. It also increases air-conditioning usage, which leads to higher fuel consumption. 

Another critical issue that a sun film for a car solves is glare, which happens during peak daylight hours, and in high-traffic zones. A glare also decreases visibility, reducing the chance of safety risks. Sun control films are an effective solution that reduces cabin heat, cuts down glare and provides a comfortable driving experience. 


How to choose an RTO-Approved Sun Control Film?


Importance of RTO Compliance: 

India’s RTO rules for a car glass’ film mandate that: 

  • Front and rear windshields should get a minimum of 70% VLT

  • Side windows should get a minimum of 50% VLT. 

By following these standards, you will ensure legal compliance and easily avoid fines and penalties. 

Here are some key factors you need to consider while choosing the right RTO-approved sun film for cars: 

  • Visible Light Transmission (VLT): Choose a film that meets or exceeds the minimum VLT requirements while still offering optimal heat and glare reduction. 

  • UV and Infrared Ray Blocking Capabilities: Look for films that block over 99% of UV rays, and infrared rays to protect passengers, and prevent interior fading. 

  • Durability and Scratch Resistance: High-quality films last longer and resist scratches, maintaining their functionality and appearance over time. 

  • Aesthetic Appeal and Privacy Needs: Select films that complement your vehicle’s look and provide adequate privacy without compromising on visibility. 

Here is a step-by-step checklist to follow when choosing what kind of sun control film for cars you need: 

  • Verify the film’s compliance with RTO regulations. 

  • Check the manufacturer’s specifications for UV and heat rejection levels. 

  • Ensure that the film has a warranty for durability and performance. 

  • Choose a professional installer to guarantee proper application without any air bubbles or scratches. 

  • Test the film’s VLT after installation and confirm that it meets all legal standards. 

Benefits of Sun Control Film


Reduced Cabin Temperature

Sun control films lower the cabin’s temperature by blocking heat from the sunlight. This helps improve driving comfort, particularly during long travels happening in hot weather. 


Enhanced Windshield Clarity

By minimising glare, these films improve visibility and safety, especially in harsh sunlight or reflective environments. 


Reduced Fading of Interiors

UV rays can cause parts of the car, such as the car seats, dashboard and other interiors, to fade over time. Sun control films for the car will protect these parts, thus extending the interior life. 


Lower Maintenance Costs: 

Using RTO-approved car glass films results in better heat insulation, thus reducing the strain on the car’s AC, further leading to lower energy consumption and decreased wear and tear on the system. 


Fuel Efficiency: 

By reducing the cooling load on your vehicle, RTO-approved films also contribute to fuel efficiency. 


Glare Reduction: 

Films minimise glare from the sunlight, headlights and other reflective surfaces, making driving safe and more comfortable. 


UV Protection: 

Blocking harmful UV rays protects the skin from getting long-term damage and reduces the health risk of skin cancer. 


Improved Glass Durability: 

Premium films also enhance the durability of car windows, making them more resistant to minor scratches and damage. 


Eco-Friendly Solution: 

By reducing energy consumption, sun films for cars support environmentally friendly driving practices. 


All-Weather Comfort: 

These films are effective in all seasons, helping maintain cabin comfort during both hot summers and cooler winters by regulating the heat inside. 


Legal Considerations


RTO-approved sun film for cars allows the following limits for sun control films: 

  • Front and rear windshields must have a minimum of 70% visible light transmission. 

  • Side Windows must allow a minimum of 50% visible light transmission. 

Failing to comply with these standards will result in penalties, including fines and the removal of non-compliant films. Garware sun control films follow these regulations strictly, meaning that you will be RTO compliant if you choose Garware Hi-Tech. 

To avoid any legal issues, make sure that: 

  • The film’s VLT matches the manufacturer’s specifications and follows RTO guidelines. 

  • You retain proof of compliance, such as product certifications or invoices. 

  • The installation is done by a certified professional who can provide documentation confirming RTO adherence. 

How it Works


Black films for cars use an advanced heat rejection technology to regulate the temperature inside vehicles. This is achieved with two mechanisms: 

  • Infrared Reflection: 

Specialised coatings on the film reflect a significant portion of infrared radiation, preventing heat from entering the car. 

  • Infrared Absorption: 

High-quality films absorb infrared heat and then disperse it, ensuring that the heat transferred into the cabin is minimal. 

 

UV Blocking Layers: 

Black films for cars, those RTO-approved especially, incorporate multiple layers designed to block harmful UV rays. UV-blocking films can prevent over 99% of UVA and UVB rays from going through the glass. This gives two major benefits: 

  • Health Protection: Reduces the risk of skin damage, premature ageing and skin cancer that is caused by prolonged UV exposure. 

  • Interior Preservation: It also stops fading, discolouration and cracking of car upholstery, the dashboard and trims. 

Advanced Film Technologies: 

  • Nano-Ceramic Films: Use microscopic ceramic particles to provide the best heat rejection and UV protection without affecting visibility. They are durable, resistant to scratch and effective in extreme conditions. 

  • Metalised Films: Feature a thin metal layer that enhances infrared reflection and durability. However, these films can sometimes interfere with electronic devices like GPS and mobile signals. 

  • Hybrid Films: Combine ceramic and metalised technology to help balance heat rejection, and UV protection and give an aesthetic appeal. 

RTO Guidelines


As mentioned above, all RTO-approved car glass films must allow 70% VLT for the front and rear windshields, and 50% VLT for the windows. 

These guidelines have been implemented to ensure road safety by maintaining clear visibility for drivers, particularly at night, and during adverse weather conditions. 
 

State-Specific Variations: 


While the central RTO guidelines apply nationwide, how they are enforced, and any penalties when they are broken vary from state to state. Some might be strict while implementing, especially in metro cities to address concerns about visibility and security. You must check the local regulations and ensure that your sun control film complies with both national and state standards. 


Alignment with Safety Standards: 


RTO guidelines are designed to balance comfort and safety. By following them, you can reduce heat and glare without compromising on visibility or creating safety hazards on the road.
