A man has died following a serious two-vehicle crash on the M1 Motorway at Mount Colah, New South Wales, north of Sydney, Australia, police confirmed on Sunday.
According to a statement released by the New South Wales Police Force, emergency services were called to the scene about 8:35 a.m. on Sunday, March 8, 2026, following reports of a crash involving a truck and a passenger vehicle in the southbound lanes of the busy motorway.
When first responders arrived, they located the car driver, a man who had suffered critical injuries in the collision. Tragically, he was pronounced dead at the scene before emergency personnel were able to provide medical assistance. Authorities said the man has not yet been formally identified as investigations and family notifications continue.
The 27-year-old driver of the truck involved in the crash was not physically injured. Police said he was transported to Hornsby Hospital for mandatory testing, a routine procedure following serious traffic incidents.
Officers from the Ku-ring-gai Police Area Command attended the location shortly after the crash and established a crime scene while specialist investigators began examining the circumstances surrounding the fatal collision. Authorities are working to determine exactly how the crash occurred, including whether speed, road conditions, or other factors may have contributed to the incident.
Police are appealing to anyone who witnessed the crash or who may have captured dashcam or mobile phone footage from the area at the time to contact Hornsby, New South Wales police or reach out to Crime Stoppers NSW.
The crash caused significant traffic disruptions along the M1 Motorway throughout the morning while investigators processed the scene. Authorities have since confirmed that the crash site has been cleared and all lanes have reopened, with traffic conditions gradually returning to normal.
