Three killed in separate crashes in Qld

Two motorcyclists and a truck driver have been killed on Queensland's roads in the space of a few hours.

A 52-year-old rider died when his bike left the road near Gympie, in the state's southeast, about 10am on Sunday. Two hours later, the second rider, 22, died near the far north Queensland town of Mt Molloy when he was thrown from his trail bike.

The truck driver, 35, also died on Sunday morning when his semi-trailer ran off the road and overturned at Kumbarilla, near Dalby on the Darling Downs.
