Instead of driving the VCE student home Rana, 30, started to kiss her and remove her clothing as she sat slumped in the passenger seat.
He then raped her and forced her to have oral sex.
Jailing Rana for six years today, County Court Judge Wendy Wilmouth said the public deserved to feel safe in taxis.
"Parents should be able to trust that their teenage children will be safe in taxis," she said.
"This girl's safety was entrusted to you when the people who helped her gave you the money for her fare, to take her safely home.
"Instead you violated that trust when you raped her."
The court heard the girl had been drinking heavily and had taken two months' worth of anti-depressants in an attempt to end her life before the November 2012 attack.
She was spotted by a group of four good Samaritans in Melbourne's eastern suburbs who tried to help her.
They hailed Rana's cab and paid him $50 to take her home.
CCTV footage from security cameras installed inside the taxi captured the attack.
Rana was arrested two days later and has been held in custody since.
The court heard he migrated from India in 2008 and had been driving taxis to support himself while studying.
He had planned to return to his middle-class family in India and has no prior convictions.
Judge Wilmouth said the attack had left Rana's victim unable to get her life back on track and had worsened depression and anxiety.
It also derailed her final year of school and has put her chances of qualifying for university in doubt, she said.
Rana, whose temporary resident visa expired in September, must serve a non-parole period of four years.
He has been placed on the sex offenders' register for 15 years and is facing deportation on release.
He has also been ordered to provide police with a DNA sample.
