A truck driver died at Hepburn Springs last night when he was crushed by his rig.

The man, who was aged in his 60s and from Hepburn Springs, had attached the prime mover to a trailer a short time before it rolled forward.

He was crushed as he tried to get into the cabin and apply the brakes; however he fell under the wheels.

Preliminary inquiries suggest the brakes on the prime mover had not been applied.

The added weight was initially supported by the trailer’s parking brakes, but a build up of air pressure in the system allowed the trailer brakes to be released.

Two people have died at work in Victoria this month.
