SINGAPORE - A lorry driver was reporting a collision between his truck and a taxi along an expressway when he was struck by another taxi while walking in the middle of the road, a court heard.

Mr Teo Heng Leong, 53, was pronounced dead at Pan-Island Expressway (PIE) at 12.37am on Sept 22 in 2015 by paramedics.

On Wednesday (Sept 28), former taxi driver David Chong Chat Tong alias Chia Chat Tong, 44, was fined $5,000 and banned from driving for five years for causing the death of Mr Teo through his negligence. He had failed to keep a proper lookout between 12.18am and 12.37am that day along the PIE and colliding into Mr Teo.

Deputy Public Prosecutor Krystle Chiang said that sometime before 12.18am that day, taxi driver Sa'adon Abdul Rahman, 66, hit the back of Mr Teo's lorry along PIE in the direction of Tuas, before the Toh Guan exit.

The lorry came to a stop along the centre of the three-lane expressway. Mr Sa'adon's taxi stopped on the leftmost lane, about 80m behind the lorry.

Mr Teo called the police. He was waiting for them to arrive and walking behind the lorry with its hazard lights on when Chong's taxi rammed into him.

DPP Chiang said Chong had switched from the rightmost lane to the centre lane and did not notice the lorry until a collision was imminent.

The right and left lanes of the PIE were clear of vehicles at the time.

She said Chong did not slow down or swerve to avoid the collision and did not notice Mr Teo until after the accident when he exited the taxi and saw Mr Teo lying along the road.

Chong, who now works as a cashier, was allowed to pay $1,000 first and the rest by monthly instalments. He could have been jailed for up to two years and/or fined for causing death by doing a negligent act.
