Hundreds of cars left with flat tyres after sharp debris spills over 30km stretch of busy motorway into Sydney

Sharp metal debris from a truck has caused significant disruption on a 30km stretch of the M1 motorway near Sydney's central coast, affecting over 300 vehicles with punctured tyres and leaving drivers in difficult conditions due to rain and darkness. Authorities have dispatched numerous tow trucks and heavy vehicle inspectors to address the incident, which requires extensive efforts to clear. While the truck had previously experienced similar incidents, the cause of this latest metal debris leak remains unclear. The incident has resulted in traffic delays and lane closures, prompting motorists to allow extra time and stay away from the area.
