A 32-year-old man was killed and four other men injured in a horror three days on Great Southern roads last week. Emergency services were called to the scene of a crash on Albany Highway near Mt Barker about 10.20am on Saturday after a head-on collision between a ute and a truck. Police say a white Toyota Hilux ute was travelling north on Albany Highway when it struck a white Iveco International truck which was travelling south on the highway near Jutland Road, north of the Mt Barker townsite. The driver of the ute, a 32-year-old man, died at the scene. The 56-year-old male driver of the truck, and his 74-year-old male passenger, were taken to hospital with minor injuries. Major Crash investigators were sent from Perth to examine the crash scene, with Albany Highway closed for several hours from Kendenup to Mt Barker. The fatal crash was one of two serious crashes in the area in the space of about 20 minutes. A short time after the Mt Barker incident, emergency services were called to another crash in Porongurup, about 40km away. The single-vehicle crash occurred near the intersection of Chester Pass Road and Porongurup Road about 10.35am. Firefighters from Albany and SES volunteers from Gnowangerup helped at the scene. The driver was trapped and had to be freed from his vehicle. The RAC rescue helicopter took the man to Perth for treatment. On Friday afternoon, a man in his 50s was injured in a crash near the Stirling Range National Park. Initial reports suggested a vehicle was travelling along Chester Pass Road about 12.50pm, when it left the road and struck a tree near Salt River Road in Amelup. The RAC rescue helicopter was deployed to the crash scene before being stood down. The man was taken to Albany Health Campus for treatment to non-life threatening injuries.
