Mr Koh was with four Singaporeans – his friend, her husband Edwin Ng and her parents – for a four-day stay in Genting Highlands and another two nights in Kuala Lumpur, with the bus leaving Singapore on Tuesday night.
Said Mr Ng, who suffered whiplash: “There was blood everywhere and it was not an option to get out of the bus because the expressway started filling up with traffic around 6am.”
The system administrator, 42, said he turned to check on his wife and found her nose bleeding profusely while her parents, who are in their 70s, were lying on the floor of the bus.
“My 75-year-old mother-in-law’s face swelled up while my 79-year-old father-in-law had a huge gash in his leg, a broken tooth and abrasions,” he said.
The wound on his father-in-law’s leg was so severe that a sanitary pad his wife had on hand could not stop the bleeding.
As the crash damaged the front door of the bus, Mr Ng said he and another passenger had to force open the emergency exit at the back of the vehicle.
About one hour passed before the Malaysia Civil Defence Force whisked all the passengers to two hospitals, he added.
At Selayang Hospital on the outskirts of Kuala Lumpur, Mr Ng said he spent an hour queuing to pay about RM1,000 (S$315) for a computed tomography (CT) scan, X-ray and magnetic resonance imaging (MRI) for his mother-in-law.
His father-in-law needed four stitches for the gash on his leg.
