The government on Friday proposed amendments to road traffic regulations to improve road safety and keep up with new technology. Among the changes is requiring electric vehicles to have acoustic warning systems to alert pedestrians. Private cars will also need to use child restraining devices, while vehicles with extendable aerial structures must have over-height warning systems installed. The proposals also include allowing remote control parking features and camera-monitor systems as alternatives to traditional mirrors. Electric commercial vehicles will also be permitted to use expressways without special permits under the new rules. In a statement, a Transport and Logistics Bureau spokesman said the government will continue updating regulations as needed to keep pace with evolving technologies and international standards. "We aim to create a safer and more convenient road environment for road users in Hong Kong through optimising vehicle design and construction standards with the amendment regulations," the statement read. The amendments will be tabled to the Legislative Council next Wednesday for negative vetting.
