A trailer truck driver and his assistant were killed in a fatal accident in Sarawak, Malaysia, on Wednesday, December 3.

The incident occurred while the pair were transporting heavy machinery when the vehicle stopped at a traffic light and the load unexpectedly shifted forward, crushing the cabin and trapping both men inside.

Emergency services responded immediately, but the victims could not be rescued. Authorities have launched an investigation to determine what caused the sudden movement of the cargo and whether safety or securing measures may have been compromised.
