HE HAD stopped his trailer at the side of the road for forty winks, and was just drifting off when the 12m-long vehicle wobbled.
Mr Shukor Ayub thought nothing of it, but seconds later, a man appeared at his window, rapping furiously.
Startled awake, he climbed out, and saw carnage.
A lorry ferrying 10 foreign workers had smashed into the back of his massive 22-wheeler. Four men were killed, six others injured.
'I didn't even realise it until someone came and told me,' said the stunned 30-year-old Malaysian.
The only damage to the trailer was a loose wheel.
But the front of the lorry was so badly crumpled, rescuers had to use a hydraulic cutter and two winches to free the body of the front-seat passenger.
The accident, which happened in Gul Road in Tuas at about 4am yesterday, is believed to be the worst so far this year.
Indian worker V. Varatharajan, 23, survived the crash.
He said that the day had started as usual for the group, who were minutes away from their workplace at a shipyard at the end of Gul Road at the time.
