An earlier accident involving a car and a motorcycle snowballed into a bigger accident, when an oncoming truck rammed into a police car at the scene, brushing past an officer.
At about 9.45am yesterday, Mr Fahmy Mahony's BMW GS Adventure collided with a stationary Honda Civic in slow-moving traffic at Lentor Avenue.
The 1,200cc motorcycle's front suspension was damaged, and Mr Fahmy, 30, could not move the 260kg bike to the side of the three- lane road in the heavy traffic.
A police car soon arrived and was parked in the middle lane of Lentor Avenue towards Ang Mo Kio, acting as a buffer to prevent vehicles from crashing into the motorbike.
Mr Fahmy, a Land Transport Authority engineer, said: "It was very dangerous for my motorcycle to be left in the centre lane.
"I thought everything was under control when they were redirecting traffic while waiting for the tow truck."
But the real drama was just beginning.
As he stood on the pavement, Mr Fahmy suddenly saw a Kia truck crash into the police car as the policeman stood beside it.
"The police officer saw the lorry just in time and his quick reflex saved him - he tried to move out of the way, but the truck grazed him and he fell," he said.
From the momentum of the crash, the police car then rammed into Mr Fahmy's fallen motorcycle, moving it 5m forward.
Meanwhile, the truck swerved to the left and crashed into a lamp post.
Mr Fahmy ran to the truck and pulled the driver out as the door was ajar.
Mr Fahmy said: "He was in a complete state of shock. He repeatedly said, 'I did not see' as I pulled him out of the vehicle."
The driver had no visible wounds but he told Mr Fahmy that he was experiencing severe chest pains.
Mr Fahmy said: "It was terrible. The policeman was trying to help, if he had not moved away, he would have been directly hit by the truck and died. He is extremely lucky."
Police said the 21-year-old police officer and the 61-year-old driver suffered only minor injuries.
The Singapore Civil Defence Force was notified of the accident at 9.50am. It dispatched one ambulance to take the two to Khoo Teck Puat Hospital.
