A BAN on importing noisy vehicles is being introduced. Noise emission standards from Europe and Japan are being adopted in the legislation, among the most stringent internationally. The plan is to reduce noise levels over the next few years by replacing most vehicles on the road with new models. 'There will not be any problem for most importers . . . since a great proportion of the vehicle fleet are Japanese and European-made models,' a government spokesman said. Importers would have to submit noise specifications of models for approval, said Environmental Protection Department senior officer Aaron Lui Shiu-wai. Some Korean-made models were unable to meet the standards, he said. The standards require a car to have a noise level below 77 decibels during acceleration. The figure is 84 decibels for a large truck. They will not apply to special purpose vehicles, motor tricycles, village vehicles and vehicles which cannot travel above 50km/h.
