The accident took place when the mother and son, both residents of Ashok Vihar in Northwest Delhi, were returning home after attending a function, police said. The car was being driven by the son, they said.
The impact of the accident was such that the woman was thrown out of the car and fell off the flyover, a senior police officer said. The car was crushed in front, she said.
