A driver in his 30s died following a six-vehicle pileup at KM31.9 of the North-South Expressway (PLUS) near the Kulai Rest and Relaxation (R&R) area. According to Kulai Fire and Rescue Station operations commander Senior Fire Officer II Khairil Mohd Adzami, the collision occurred on the morning of June 23, resulting in multiple vehicles catching fire. Authorities confirmed the victim was pronounced dead at the scene by Health Ministry personnel.
What caused the multi-vehicle collision near Kulai?
Emergency responders arrived at the scene at 10:03 a.m. after receiving a distress call at 9:02 a.m. The crash involved six distinct vehicles: a container lorry, a 40-foot trailer transporting metal fencing, a pick-up truck, a van, a 10-tonne lorry carrying mosaic tiles, and a one-tonne bonded lorry. Khairil Mohd Adzami stated that while the trailer driver succumbed to his injuries, four other drivers—aged 29, 32, 29, and 34—were reported safe and uninjured. The drivers of the container lorry and the 10-tonne lorry were not present at the site when fire department officials began their operation.
High-speed expressways like the North-South Expressway utilize emergency response protocols that prioritize fire suppression and victim extraction. In this incident, fire crews were tasked with managing flames that caused between 60% and 90% damage to the involved vehicles.
How do fire damages impact vehicle recovery and investigation?
The intensity of the fire significantly complicates the forensic investigation of the crash. According to the Fire and Rescue Department, the pick-up truck and the van sustained 90% fire damage, while the trailer suffered 80% damage. The 10-tonne lorry and the one-tonne bonded lorry both sustained 60% damage. Forensic investigators typically rely on vehicle telemetry and structural integrity to determine the cause of high-speed collisions; however, fire-ravaged wreckage often obscures mechanical evidence, making the recovery of electronic control units (ECUs) more difficult for police investigators.
Future trends in expressway safety technology
Transportation authorities are increasingly looking toward Advanced Driver Assistance Systems (ADAS) to mitigate the risk of multi-vehicle pileups. Industry experts suggest that the integration of automatic emergency braking (AEB) and vehicle-to-everything (V2X) communication could allow lorries to “talk” to one another, providing warnings of sudden stops before they are visible to the human eye. As logistics companies expand their fleets, the implementation of mandatory fatigue-monitoring sensors in heavy-duty vehicles remains a primary safety focus to prevent incidents on long-haul routes like the PLUS highway.

Pro Tip: Staying safe on heavy-traffic corridors
When driving on major expressways, maintain a “three-second gap” between your vehicle and the heavy transport ahead. If you see smoke or a collision, pull over safely to the shoulder and alert emergency services immediately rather than attempting to approach burning vehicles yourself.
Frequently Asked Questions
- What should I do if I witness a highway accident?
- Contact the emergency services immediately. Provide your exact location, typically found on the highway kilometer markers, and stay behind the safety barrier.
- Why are multi-vehicle crashes on expressways often severe?
- High speeds and the presence of heavy commercial vehicles create significant kinetic energy. According to the Fire and Rescue Department, fires often break out due to fuel tank ruptures during high-impact collisions.
- Are there specific regulations for heavy lorries on the North-South Expressway?
- Yes, heavy vehicles are subject to strict speed limits and lane restrictions to minimize the risk of accidents with lighter passenger vehicles.
