Two men killed on Perth roads

A male motorcycle rider has been killed in a crash on a Perth freeway.

Police say a vehicle was parked on the right-hand side of the freeway heading southbound, near the South Street exit, just before 9.30am (WST) on Thursday when a police officer pulled over in the emergency lane on the left-hand side.

The traffic officer was trying to communicate with the driver when a car also travelling southbound collided with the stationary vehicle.

The crash caused a further collision with a motorcyclist, who was killed.

Major Crash officers are at the scene while Internal Affairs officers are also investigating.

In a separate accident on Thursday morning, a cyclist died in hospital after he was hit by a car in Rockingham, in Perth's south, just after 6am (WST).
