A COUPLE and their son who were injured when their car and a bus collided have issued a writ in the Supreme Court. Yau Kwan-kong, 43, a fruit-stall keeper, his wife Sze Sau-chun, 37, and their son Yau Cheuk-wa, 14, are seeking damages from the driver of the bus, Shum Kwok-wa, and the New Lantau Bus Company at Silvermine Bay, Lantau. On August 23 last year at about 2.30 pm, the family was in a vehicle being driven by Mr Yau along Keung Shan Road near Shek Pik reservoir. They claim the collision with the bus was caused by the negligence of the defendants. The plaintiffs claim the driver was driving too fast, was not keeping a proper look-out and was drifting onto the wrong side of the road. Shum was charged with careless driving at Western Court on March 1 and fined $500. Mr Yau suffered lacerations and the fracture of a facial bone. He suffered five per cent permanent disability and 10 per cent loss of earning capacity, it was stated. Two of Ms Sze's ribs were fractured, causing three per cent permanent disability which could rise to 10 per cent if a knee condition worsens. Their son suffered a fractured collar-bone, the writ stated. The family is claiming special damages of more than $40,000 and damages, interest and costs.
