A police officer participating in a ride commemorating police who have died in the line of duty has been killed after a car smashed into his motorbike.
Victoria Police say the car was travelling along the Princes Highway near Orbost on Friday afternoon when it veered onto the opposite side of the road about 2.20pm and struck the policeman's bike.
He died at the scene.
The officer was among 300 riders in the Wall to Wall Ride who set out from the Victoria Police Memorial in St Kilda Road, Melbourne headed for Merimbula and then on to Canberra on Saturday.
The male driver of the car stopped at the scene and is assisting police with their enquiries, Victoria Police said.
The Princes Highway is currently closed from Marlo Road, Orbost to Cabbage Tree Creek, and traffic is being diverted along Marlo-Cabbage Tree Road.
Detectives are investigating the incident.
