A man was airlifted to Royal Perth Hospital with serious injuries after becoming trapped in his car that collided with a truck, forcing the closure of Albany Highway for several hours south of Mt Cooke on Friday afternoon. At about 1.50pm emergency services were called to serious crash after a small hatchback and truck collided near McDowall Road in the Shire of Wandering. Crews from Armadale Fire and Rescue Service and Boddington SES were able to extricate the man from his vehicle. The RAC Rescue Helicopter was sent to the scene and a man in his 30s was flown to RPH with serious injuries. He was in a stable condition on Friday night. The male truck driver was not injured in the smash. A Department of Emergency Services spokesman said firefighters worked to free the injured driver and the RAC Rescue Helicopter arrived at about 2.30pm to transport him to Perth. Albany Highway was closed Reg Road and McDowall Road for several hours, causing major delays with holiday traffic. DFES said that about 400 litres of diesel had been spilt on the busy route from the crash. At 5.37pm Main Roads confirmed that one lane of Albany Highway had been re-opened to traffic as the clean up continued.
