SINGAPORE - Two men were hurt in a chain collision involving four cars at the Woodlands checkpoint in the early hours of Sunday (July 1).
The police said that they were alerted to the accident involving four cars at the Woodlands checkpoint at about 3.30am.
Two men who were drivers, aged 32 and 51, were conscious when taken to Khoo Teck Puat Hospital.
The Singapore Civil Defence Force, who received a call for assistance at around the same time, said that the two men suffered minor injuries.
The Straits Times understands that the accident involved three Singapore-registered cars and a Malaysian-registered car.
Police investigations are ongoing.
Photos and a video posted on road traffic Facebook page SG Road Vigilante show the early morning wreckage.
It includes a black Subaru with severely damaged front bumper and hood.
At least two other cars were crushed at the rear and the passenger doors were dented.
The accident led to a 1 1/2-hour closure of the departure viaduct at the Woodlands checkpoint on Sunday morning.
The Immigration and Checkpoints Authority (ICA) said in a Facebook post at 4am that the viaduct was temporarily closed due to a traffic accident, and advised motorists to drive carefully and listen to instructions from officers.
At 5am, ICA told motorists to use the Woodlands Crossing when departing Singapore.
The departure viaduct reopened at 5.30am, ICA subsequently said.
Sunday's accident comes a day after a fatal accident near the Woodlands checkpoint killed two men and injured three others.
The accident, which happened at about 1am, involved a trailer, a lorry and three motorcycles.
A 30-year-old trailer driver was arrested for suspected drink driving, while a 23-year-old lorry driver, who was one of the injured, was arrested for allegedly causing death by rash act.
