A man whose fiancee and two friends died when the speeding car he was driving crashed and caught fire last year was jailed for 20 months yesterday. Driver Ng Pak-wing, 29, and another passenger survived with serious injuries when his red Subaru WRX crossed double white lines at a bend after he lost control and hit a concrete divider in the opposite lane at 106km/h. The speed limit on the road was 70 km/h. The collision sent the car airborne for 3.5 metres before it flipped on its side at the flyover outside Sunshine Kowloon Bay Cargo Centre in Kwun Tong, in September, and burst into flames. Ng, who choked back tears throughout yesterday's District Court hearing, pleaded guilty to dangerous driving causing death to three passengers - aged 23, 24 and 29. The charge carries a maximum five-year jail term. Judge Stanley Chan Kwong-chi described the accident as a merciless tragedy which had left the defendant with permanent guilt, physical pain and mental trauma for life. Ng appeared in court with serious burn marks on his face and arms. He was limping and had to support himself with a walking stick. The court heard in mitigation that Ng had suffered insomnia, nightmares and had become depressed and suicidal after the accident. The judge, who also disqualified Ng from driving for five years, accepted his guilt and remorse. But he said a deterrent jail term was needed because Ng had failed to improve his reckless driving manners despite his seven previous traffic convictions since gaining his licence in 1998. The professional truck driver had previously been fined and disqualified from driving on charges related to speeding, careless driving and drink driving.
