A truck has been issued with a defect notice after two of its wheels flew off on a Sydney motorway.
Police saw the incident on Tuesday during a patrol of the M7 at Horsley Park, in Sydney's west, and say the truck driver is very lucky to be alive.
The tyres were flung into north and southbound traffic, narrowly missing oncoming vehicles.
"It was quite fortunate one of our traffic and highway patrol cars was stationed on the M7 at the time and was able to assist in containing the situation very quickly," acting assistant police commissioner Stuart Smith said in a statement.
The 35-year-old driver was issued with a defect notice, which prevented him from driving away the truck.
The news comes two weeks after a fuel tanker, owned by Cootes Transport, crashed in Mona Vale, in Sydney's north, killing two people.
NSW Roads and Maritime Services has grounded 10 vehicles and issued the company with 244 defect notices during inspections.
Mr Smith urged truck operators to ensure their vehicles were regularly maintained."Your actions can have serious implications for others, so it is vital that the utmost care is taken when travelling on our roads," he said.
