How Dark Can Your Glass Be?

What is VLT?

Visible Light Transmission is the percentage of visible light that passes through the glass and film together. Higher number means clearer glass. CMV Rule 100 and IS 2553 (Part 2) (First Revision): 2019 set the minimum, subject to periodic amendments.

70%

Windscreen & Rear Glass

At least 70% of visible light must pass through.

50%

Side Glasses

At least 50% of visible light must pass through.

See What a VLT Number Looks Like

The law measures glass and film together. Pick a film shade and your glass clarity to see the estimated combined reading, how dark it looks from inside, and whether it should clear the minimum for each glass position.

An estimate for illustration only. The same film measures differently on different glass, so always ask for a VLT meter reading after installation.

VLT Meter

Measured, Not Guessed

A VLT meter reads how much light passes through your windows, so you can check it against the 70% and 50% limits.

  • Reads glass and film together
  • Checks whether windscreen & rear glass reach 70% or more
  • Checks whether side glasses reach 50% or more
  • Ask your Ultraguard installer for a reading after fitting

Window Film Laws

Frequently Asked Questions

Yes, if it meets the rule. Since 1 April 2021, Rule 100 of the CMV Rules (as amended by G.S.R. 457(E)) recognises safety glazing that conforms to IS 2553 (Part 2) (Revision 1): 2019. Windscreen and rear glass must transmit at least 70% of visible light, and side glasses at least 50%. Anything darker isn’t permitted.
In Avishek Goenka v. Union of India (27 April 2012), the Supreme Court directed that no black film or other material be pasted on windscreens and side glasses of vehicles. That order came before the 2020 amendment introduced safety glazing. Enforcement practice can vary between states, so keep your installation invoice and VLT reading with you.
On the glass and film together. Factory glass already blocks some light, so the final reading on your car is always lower than the film’s own VLT. A VLT meter gives the real combined number after fitting.
The rule places the duty on the vehicle owner to maintain the required light transmission. Choose a compliant shade with your installer and ask for a meter reading.
No. If the combined reading falls below 50%, the glass doesn’t meet Rule 100 in any position on a road vehicle in India. A 5% or 35% film always goes below that.
The legal limit of window tints in India is 70% for the front and rear windshield and 50% for the side windows. If you choose a non-compliant film, the result can be a fine, challan or instant removal of the window film.
The Ministry of Road Transport and Highways (MoRTH) manages window tinting laws in India through the Central Motor Vehicles Rules (CMVR), 1989. Enforcement of these laws, penalty collection, and compliance monitoring are managed by the Regional Transport Office (RTO). These laws are also subject to change via the Hon’ble Supreme Court of India.
When you visit an installer for window tint application, ask them to measure the film with a window tint meter. This equipment shows the VLT, IR rejection and TSER of the film. After the demonstration, you can choose a film that sits within the legal parameters.
Yes. Strict compliance with tinting laws is mandatory in India. Failing to comply can lead to immediate legal, financial, and procedural penalties. Traffic police will issue an on-spot or electronic challan. Fines start around ₹100 to ₹500 for a first offence under Section 177 of the Motor Vehicles Act and can scale up to ₹5,000. Police can also order on-spot removal.
Yes, you can. Factory-tinted glass is usually very light and can fail to reject significant heat and UV, so window tinting is still an option. But note that the legal limit applies to the VLT of your glass and film together. If your glass is 80% VLT and you choose a 70% VLT film on top of it, the combined reading will be about 56%, which is fine for side glass but below the 70% needed for the windscreen and rear glass.
