SINGAPORE - A driver was arrested for drink driving after crashing into a van on the Ayer Rajah Expressway on Saturday (March 4).
No injuries were reported in the accident before the Normanton exit in the direction of Tuas, police said.
The 25-year-old driver was driving a black BMW which overtook a few cars before the crash, according to a video posted by Mr Mustafa Danial on road safety site Roads.sg.
Mr Mustafa, who was in the first lane, told The Straits Times that he saw the BMW coming up behind him from about 150m away.
Before he could give way to the fast-approaching car, the BMW had overtaken him and another car by switching to the third lane.
A few minutes on, the video from Mr Mustafa's dashcam showed the collision happening in the distance.
The Straits Times understands that the van was behind a lorry, and was in the process of changing to the first lane to overtake the slower vehicle when the BMW crashed into it from behind.
The BMW pushed the van about 30m before they came to a stop, Mr Mustafa said.
Mr Mustafa, a 24-year-old undergraduate, said it was very smoky and the airbags were deployed.
He opened the car door and asked the driver if he was all right but the driver swore at him, Mr Mustafa said.
There was also a woman passenger, who had slid into the space under the dashboard.
The van's back wheels were broken but the van driver could get out of the vehicle and walk around, he said.
Mr Mustafa and his passenger then helped to direct traffic until the authorities arrived. They were at the scene for about two hours to assist with the investigations, he said.
Police said that a 25-year-old car driver was arrested for drink driving and investigations are ongoing.
