A motorcyclist died from his injuries after he allegedly ran a red light and collided with a car at the junction of Still Road, Koon Seng Road and Lorong J Telok Kurau on Friday morning.
The 27-year-old suffered multiple fractures and head injuries, the Singapore Civil Defence Force (SCDF) said in response to queries from The Straits Times.
SCDF was alerted to the accident at about 6.30am and dispatched an ambulance to the scene.
He was taken conscious to Changi General Hospital, where he died later that day, said a police spokesman.
In a Facebook video posted by road safety interest group Roads.sg on Saturday, a car is seen making a right turn at the junction when the motorcycle rams into its side with a loud "bang".
The traffic lights were in the car's favour at the time of the accident.
The impact throws the motorcyclist up in the air and over the car.
The video was submitted by user Louis Tan, who wrote that "the motorcyclist beat the traffic light by almost three seconds".
Police investigations are ongoing.
