First do not be over disturbed if you are having a valid driving license and third party insurance clause. Search the area and find out the CCTV cameras if any in surrounding areas, and seek that footage under RTI Act, as it helps you to establish that you are carefully driving the vehicle.
Some bad times can not be avoided even though you are vigilant and such things happen out of our misfortune. Do not worry unnecessarily and keep prepared all the evidence ready.
