Calibration tests for Automated Awareness Safety System (AWAS) speed cameras will be conducted at the Bukit Beruntung to Sg Buaya stretch on a specific timeline.
Lane closures are expected tonight from 11pm to 3am the following day at KM431.55 southbound towards KL.
AWAS will be upgraded to use a point-to-point method, monitoring average vehicle speeds between two points to determine violations.
Drivers are advised to be cautious, follow traffic signs, and cooperate with crew in the affected work area.
