One incident that happened two days before in NH17. I was going in reasonably good speed and I was about to overtake a stopped Omni. But the car behind me didn't see the omni and he overtook me at the same time I turned my indicator on. Actually When I looked at RVM the other car was at the blind spot. I had to apply a sudden brake as the stopped Omni was few meters ahead. Lesson1: Never stop the vehicle on road. You may think others have enough time. But there can be instances where your stopped vehicle can take life others Lesson 2 : Always careful about vehicles hidden in blind spots Lesson 3: This was most important thing. Two of my colleagues were in the car and we were returning after booking hotels for a conference and the other two persons were talking to each other and also to me. Usually I always keep a eye on RVM/ORVM and get a feeling of the vehicle behind. But the chatting of my friends diverted my attention for a second. Never talk too much while driving and when others drive.
