But still he couldn't completely avoid the accident and the auto and our car collided, bcz of which the auto fell and the 2 persons inside the auto were injured. our car broke down in the middle of the road. we took the injured to the hospital and we went to police station to settle things, but police took the statement of auto driver and files FIR without taking our statement. the auto driver haven't filed any complaint because he had no documents of vehicle and he didn't even have a DL.
