The woman was seriously injured in the crash in Uttar Pradesh state on Sunday. Two of her aunts were killed and her lawyer was seriously injured. Her family and opposition MPs have alleged the crash was a deliberate attempt on her life.
BJP lawmaker Kuldeep Sengar is in jail awaiting trial charged with raping her. He was charged under India's stringent child protection laws, since the teenager was a minor in 2017, when she claims he attacked her. But he has consistently denied the allegations.
Mr Sengar's lawyer, Awadhesh Singh, told Reuters that Sunday's crash was "just an accident" and that the allegations were intended to politically damage his client. On Monday night, activists held a protest in the capital, Delhi, to show solidarity to the woman, who remains in a critical condition in hospital.
