Traffic management says the updated guardrail height standard is part of continuous improvement, and road safety measures. They will work closely with the road builders and maintenance teams to ensure the smooth implementation of the new standards. At the same time, road safety education for the public will also be strengthened to improve drivers' awareness and compliance with the new standards.
