Sun control films, or sunfilms, are a hit with car owners in India for cutting heat, blocking UV rays, and adding privacy. But are they legal? Yes, if they follow strict rules. Here’s a simple guide to sunfilms and Indian law as of February 25, 2025.
The Law Basics
Back in 2012, the Supreme Court banned dark tints that made car windows too hard to see through, citing safety and crime risks. Now, updated rules from 2020 (Central Motor Vehicles Rules) allow sunfilms if they let enough light pass through. This is measured by Visible Light Transmission (VLT)—the higher the VLT, the more light gets in.
Legal Limits
These rules apply to both factory-tinted glass and films you add later. Anything darker—like fully blacked-out windows—is illegal.
Why These Rules?
The law ensures drivers can see out and others (like police) can see in. A 2024 Kerala High Court ruling confirmed you can add films after buying your car, as long as they meet these limits.
Benefits of Legal Sunfilms
Brands like Garware offer films that meet these rules and come with proof of compliance.
Breaking the Rules
If your windows are too dark, expect a fine—starting at ₹500, up to ₹1,000 or more if you’re caught again. Cops might also make you peel off the film right away.
Tips to Stay Legal
-
Pick Certified Films: Look for ones tested to Indian standards (IS 2553).
-
Check VLT: 70% for front/rear, 50% for sides.
-
Keep Proof: Carry the certificate or receipt.
-
Get It Done Right: Pros install it better than DIY.
-
Know Your Area: Rules are the same nationwide, but enforcement can vary—check with your local RTO.
The Catch
Some say these limits make sunfilms less effective against heat, and enforcement can be spotty. Still, modern films manage to help while staying legal.
Bottom Line
Sunfilms are fine in India if they’re not too dark: 70% VLT for front and rear, 50% for sides. Stick to certified options, and you’ll enjoy the perks without breaking the law. Easy, right?
