A video emerged online showing a Mitsubishi Lancer speeding dangerously along the CTE, before crashing and being overturned on the road.
The Mitsubishi Lancer was seen in the video trying to change lanes while speeding, but the driver then lost control of the vehicle and swerved into another car.
It then crashed and turned “turtle” on the road shoulder.
Two people were subsequently sent to Sengkang General Hospital by officers from the Singapore Civil Defence Force.
The video emerged on the Facebook page of SG Road Vigilante, and the accident took place somewhere along the CTE at about 6.45pm.
At the beginning of the video, the Mitsubishi Lancer was seen speeding along the expressway and as it neared the camcar, the Lancer then swerved to the right.
It then hit a black coloured SUV before crashing on the left side of the road shoulder and overturning on the side of the road.
The SUV that was hit by the Lancer also lost control and swerved across four lanes, before ultimately coming to a halt on the left side of the road shoulder.
The Singapore Civil Defence Force confirmed that the accident took place on 30 January at about 6.50am along the CTE after the Ang Mo Kio Avenue 3 exit.
The SCDF said that they sent two people to the hospital.
