A tow truck driver was reportedly killed in a fatal car crash on North Lantau Highway on Sunday shortly after midnight, leading to a temporary closure of the major traffic artery to the airport for an hour. The accident also prompted another three-car collision on the same road. The 37-year-old tow truck driver, surnamed Kwok, was travelling along the highway towards Hong Kong International Airport at 12.50am on Sunday morning. Kwok was called to Sham Shui Kok Drive to tow away a private car – a red Audi, which had stopped by the side of the road due to a flat tyre. The 24-year-old Audi driver – surnamed Lau – and Kwok were standing by the road as Kwok was loading the Audi onto the truck. A medium goods lorry reportedly knocked Kwok down, colliding with the truck and Audi. “The [force of the impact] pushed the private car 12 metres and the tow truck 50 metres away. The truck driver was hit and suffered serious injuries to the head,” Chan Wing-fai, senior inspector of the Special Investigation Team of Traffic, New Territories South, said. “The medium goods vehicle was not speeding when the accident took place. We will look into the driving attitude of the driver and road condition.” The truck driver was rushed to North Lantau Hospital unconscious, and was certified dead at 1.30am. The fatal crash became the second tragic blow to Kwok’s wife in a single day. On Saturday morning, less than 24 hours before the crash, she reportedly learned from doctors she had suffered a miscarriage. The 45-year-old lorry driver, surnamed Wong, was arrested for dangerous driving causing death and was being detained for further inquiries. It is understood he passed a breathalyser test. The rear of the Audi was completely damaged. Both Wong and Lau were reportedly unhurt in the accident. The fatal crash caused traffic to come to a halt, and just five minutes later, near the scene of the accident, a tour bus reportedly rammed into a container trailer and a lorry in front when it could not brake in time. The 46-year-old tour bus driver and a six-year-old female passenger suffered minor injuries to their head and legs respectively. They were discharged after receiving treatment in North Lantau Hospital. Both lanes of North Lantau Highway were closed for an hour due to the accidents. Lanes in the direction of the airport were completely opened by about 6am. The police were urging members of the public who witnessed the accident or have any information to contact investigating officers.
