Seremban police chief Hatta Che Din said the incident occurred at about 4pm at Km254.6 of the highway heading towards Seremban.

He said the 4WD, driven by a 65-year-old man with a 54-year-old female passenger, was heading towards Shah Alam from Rembau.

Hatta said the vehicle was on the emergency lane when it braked suddenly. The motorcyclist on a BMW bike tried to swerve to the right to avoid it, but scraped the right brake light.

The rider fell onto the left lane of the highway and was run over by a trailer. He died at the scene from severe head injuries.

Another motorcyclist also rear-ended the 4WD drive on the emergency lane, but he was unharmed.

“The driver of the 4WD did not not suffer any injuries,” Hatta said, adding that the case was being investigated for causing death by reckless driving.
