I had to cough up 100 bucks for the tint on my rear window. Well, my car is Andhra Pradesh registered and I am currently using it in Chennai. The cop (actually there were a bunch of em ) stopped me on my way to office at Tharamani, I was coming from Tiruvanmiyur RTO. The moment he looked at the reg plate, he stopped me (I have been using this route for the last 3 months and nobody ever stopped me) and said show me the NOC. I said I travel quite frequently between Hyderabad and Chennai, he asked how can you prove it (actually I was waiting for this question). I slapped the toll receipts and the fuel bills on his face, well I kept smiling and he did too. Then he came closer and started checking the windows for the tint, I had removed them already. He was like what is this on the rear glass I cant see anything inside - I told him its company fitted and I cant remove it because of the warranty issues. He was actually waiting for me to agree that there is some kinda tint and there you go, he got an opportunity. He said dont you know the apex court ruling and blah blah..while doing that he prepared a receipt for 100 bucks. I was like Is there a way to escape this guys ? I dont want to remove the tint on my rear windshield either !
