Six people were injured in a dramatic accident involving a taxi and a lorry on Mandai Road on Saturday night.
The accident took place at about 9.40pm along the stretch towards Woodlands Road.
A Singapore Civil Defence Force spokesman said that six people were sent to Khoo Teck Puat Hospital. Four of them had minor injuries such as cuts and bruises.
The other two were a 46-year-old man, believed to be a cab passenger, who complained of chest pains, and a 13-year-old girl who was believed to have suffered a spinal injury.
No one was trapped in the vehicles.
According to Chinese evening daily Lianhe Wanbao, the taxi was carrying a family of four South Korean tourists, including the 13-year-old girl.
They were believed to have just left the nearby Night Safari when the Premier taxi they were in collided with a lorry.
Eyewitnesses said the teenage girl was thrown out of the cab and landed 5m away.
The impact of the crash caused the lorry to spin around before flipping over onto its back, while the taxi had its front smashed and its windshield shattered, reported Wanbao.
Bits of glass and vehicle parts were strewn on the road.
The lorry driver was able to climb out of the vehicle on his own and wait on the side of the road for paramedics to arrive, said eyewitnesses.
The other passengers in the taxi also exited the vehicle on their own and appeared to be in shock.
Mangled vehicle parts were still left on the side of the road yesterday morning.
A police spokesman confirmed that they had received a call about the accident and investigations are ongoing.
There were at least two other serious accidents along Mandai Road this year.
In March, a 24-year-old man, believed to be a Malaysian, fell into a coma after he lost control of his car and crashed into a tree.
The following month, a Singaporean cyclist in her 40s who was riding along the road was admitted to intensive care after a hit-and-run accident.
