Lorry driver arrested after drug test following Shah Alam multi-vehicle collision

The incident occurred at a traffic light junction in Shah Alam when the heavy vehicle ploughed into a series of stationary or slow-moving cars. Emergency responders attended to the scene, and the driver was subsequently subjected to drug screening as part of standard accident investigation procedures.

Drug test results came back positive, prompting authorities to launch a formal investigation into the circumstances surrounding the collision. The positive result raises questions about the driver's fitness to operate the vehicle at the time of the incident.

The driver attributed the crash to brake failure, claiming the vehicle's braking system malfunctioned at the critical moment. Authorities are now examining both the mechanical condition of the lorry and the driver's actions to determine the primary cause of the accident.

The collision resulted in significant damage to the 11 vehicles involved, though initial reports did not specify the extent of injuries, if any. The incident has prompted renewed attention to road safety standards for commercial vehicles operating on Malaysian highways and urban roads.
