Windshield and Window Visibility Rules
Dark window tints beyond the legal limit are banned. Windshields must allow at least 70% light transmission.
The Supreme Court of India (2012) banned all aftermarket window tinting/films. Factory-fitted tinted glass must allow at least 70% light transmission on the windshield and front side windows, and 50% on the rear. Any aftermarket sun film is illegal.
Penalty Under Law
₹500–₹1,500 (Sec. 177). Police may remove illegal tint on the spot.
Legal Source
MV Act Sec. 100; CMVR Rule 100; Supreme Court order (2012)
What the Law Says
CMVR Rule 100: Front windshield must have minimum 70% Visual Light Transmission (VLT). Side windows (front): 70% VLT. Rear windshield and rear side windows: 50% VLT. The Supreme Court in Avishek Goenka vs Union of India (2012) upheld the ban on all aftermarket sun films, even transparent ones. Only factory-fitted tinted glass is permitted within VLT limits.
💡 Why This Rule Exists
Dark window tints prevent traffic police from seeing inside the vehicle — a security concern related to kidnapping, smuggling, and VIP culture. For driving safety, excessive tinting reduces the driver's visibility at night and in low-light conditions, and prevents other road users from making eye contact with the driver at intersections.
