Be courteous while passing against any stuck vehicle in the water logged area,
Since ur vehicle is stable & able to sail through, u can drive gentle & avoid ‘too much’ splashing on the stuck car & the people in it.#Humanity #ChennaiRains #அன்பைவிதைப்போம் https://t.co/6lvn7XK7zx pic.twitter.com/ouopKwZi8P
