The tragedy in Guangdong over the Lunar New Year is the latest in an unacceptably long line of similar accidents. While it is true that road travel inevitably involves a certain amount of risk, there is no doubt that the death and injury toll among Hong Kong people travelling by coach on the mainland has reached a level that demands urgent action. The Hong Kong Government cannot force the mainland to regulate to keep unsafe drivers and operators off the road; it can only lobby for standards to be improved. And holidaymakers have a right to know the standard of holiday they are buying. It is time therefore that Hong Kong took the initiative by imposing standards that mainland operators must meet before receiving a seal of approval from the travel industry here. Customers could then choose between an operator they know conforms to basic safety requirements, or one who does not; in which case, caveat emptor.
