Police are considering changing traffic laws to enable the prosecution of owners of cars involved in speeding offences. Under the proposal, the vehicles' owners would be immediately identified through computer records and be held liable. 'The move will not only save money but will also be easier to implement,' Senior Superintendent Allan Wong Sak-pang said. Speeding drivers now face immediate prosecution, or are traced by police with the owners' co-operation, a process taking at least 1.5 months. However, Mr Wong said it would be some time before the change would be introduced. Police and the Transport Department yesterday unveiled the latest camera system to curb speeding on expressways. A round-the-clock automatic camera system has been installed on 10 designated areas on main expressways in the New Territories, including six on Fanling Highway and four on Tolo Highway. Police said the Speed Enforcement Camera System, with a 24-hour radar speeding detector, would be in use from January 15.
