Truckie admits crash role

A wheelchair-bound truck driver has admitted causing the horrific crash that killed a Kalgoorlie father and son in February.

Kevin Paki, 54, and his 21-year-old son Brian were in their car at a railway crossing on Great Eastern Highway near Kellerberrin when a prime mover truck smashed into the back of the vehicle.

Witnesses described how the car burst into flames as it was pushed through boom barriers, across the level crossing and off the edge of the opposite side of the highway by the truck.

Both men, who were returning home after taking another son to Perth to start university, were trapped inside the burning vehicle and died at the scene.

In Perth Magistrate's Court yesterday, NSW man Jeffrey Moyle, 45, pleaded guilty to two counts of dangerous driving causing death.

The court had been told that Moyle, who was wheelchair-bound before the crash, was on a long-haul drive for JDH Transport when he failed to stop his truck.

A sentencing date in Perth's District Court will be set during a hearing in September.
