A school bus driver is being sued for crashing into a Wharf Cable car, pushing it off a road into a construction site in an accident which killed two men and injured 16 children. The High Court action was launched by Lee Yim-kuen, the widow of Wharf Cable surveyor Wong Wai-ming - one of the two men trapped and killed inside the vehicle on the afternoon of September 23, 1996. Firemen struggled for two hours to free Wong and Wu Chi-keung from the wreckage. Sixteen children on the school bus were injured. According to the writ, Lam Wai-ho, then 25, was driving the school bus down Hill Road in Sai Wan and hit the Wharf car, which had stopped at a traffic light. Wong, 34, was in the front passenger seat with Wu at the wheel of the Wharf car at the junction of Queen's Road West and Hill Road, the writ states. 'The impact of the collision was so great that the deceased's vehicle was pushed from the road into [an adjacent] construction site,' the writ says. It alleges Mr Lam was negligent in driving a vehicle with a 'defective front service brake'. He had been convicted in Western Court of careless driving and using a defective vehicle. He was fined $3,000. The writ also accuses Mr Lam of failing to heed and stop at the 'give way' sign. Ms Lee is suing for an unspecified sum for Wong's dependants and his estate.
