A seven-month-old infant and her parents died after their vehicle overturned several times when it was rammed by a speeding vehicle on the Duke Highway in Kuala Lumpur.
The impact of the crash caused the three of them to be thrown out of their Mitsubishi Pajero Sport, reported Malaysia's The Star.
The family had earlier attended a relative's wedding in Putrajaya.
They were hit by a Perodua Myvi, which is believed to have been racing with four other cars of the same model.
Mr Fairuz Nizam Husain, 35, died on the spot in the tragedy, which happened at 1.05am on Saturday.
His wife, Madam Nova Safitri Azhari, 27, and daughter suffered severe injuries and died at the Kuala Lumpur Hospital (HKL).
They are survived by the couple's two other daughters, aged seven and three.
Investigations revealed that their car was hit from behind when they were trying to merge into the fast lane.
Mr Fairuz lost control of his Pajero before swerving into the left lane and crashing into another car.
"Their vehicle overturned a few times," said Kuala Lumpur Staff Officer for Traffic Investigation and Regulation Deputy Superintendent Markandan Subramaniam.
Mr Markandan said a woman driver was arrested while she was seeking treatment for a bruised lip at HKL.
"She was driving the Myvi which hit the victims' Mitsubishi Pajero. We have also identified the driver of the other Myvi, which crashed into the victims' car before it spun around," he said.
The case is being investigated as one of reckless driving.
Representatives of the "Myvi club", which the suspects belong to, have denied eyewitness accounts that they were racing.
Mr Fairuz's brother, who wanted to be known only as Mr Hamlizar, 43, said the family was shocked by the event.
He said: "We still need some time to digest the news. My brother's two other daughters have been informed of their parents' death."
