As a taxi driver, he was supposed to send his passengers to their destination safely.
Instead, Ang Wei Leong, 37, molested four unsuspecting women between October 2013 and last June.
The married man was jailed for nine months yesterday after pleading guilty to two counts of outrage of modesty.
Three other counts of molestation and a theft charge were taken into consideration during sentencing.
One of the victims, a 31-year-old woman, boarded Ang's taxi with a friend at Clarke Quay around 4.40am on Oct 31, 2013.
She sat directly behind the cabby and rested her head against the headrest of his seat. She was feeling drowsy as she had earlier consumed alcohol, the court heard.
Ang drove the friend home before making his way to the Serangoon area, where the woman lived.
Noticing that she was asleep during the journey, he stopped his taxi, turned around and molested her, by rubbing her breast with his hand.
The woman was roused awake and felt that she had to throw up.
Seeing this, Ang got out of his seat and slipped into the space beside her. He passed her a plastic bag and while she was vomiting, he squeezed her breasts a few times.
He stopped molesting her when she was done and drove her home.
Ang struck again about eight months later when he picked up a 42-year-old woman near Concorde Hotel on Orchard Road.
He was driving to her home in the northern part of Singapore when he told her that he had two bottles of beer in his boot.
He asked her if she wanted to find a place to drink them with him, but she declined.
Despite this, Ang drove to the deserted Yishun Dam and stopped the vehicle to retrieve the drinks.
Deputy Public Prosecutor Krystle Chiang said: "Fearing for her safety, the victim alighted from the taxi and sat on a kerb. She observed that there was no one else around at Yishun Dam."
Ang then sat beside the woman and hugged her. When she pushed him away, the cabby tried to kiss her face, but she managed to block him.
The pair returned to the taxi after Ang finished his beer and he drove her home.
During the journey, the terrified woman sent a text message to her godsister, giving the taxi's registration number.
Ang's lawyer, Mr Jeremy Pereira, said in his mitigation that his client had ensured that the first victim reached home safety as she was intoxicated.
However, before handing out the sentence, District Judge Michelle Yap said members of the public must be protected so that they have confidence when taking public transport.
For each count of outrage of modesty, Ang could have been jailed up to two years, or fined, or caned, or given any combination of such punishments.
