A driver has been charged after a truck spilled about 840 kilograms of metal fragments on a major NSW road, which damaged the tyres of more than 300 cars.
The spill resulted in major traffic delays before the major road was reopened almost 10 hours later.
Many of the vehicles with tyre damage were stopped in the breakdown lane.
There were no reports of any injuries.
Police said officers spoke with the driver of the vehicle, a heavy vehicle tipper towing a trailer, about the matter on the day of the incident.
Police will allege the secondary locking handles on the trailer were not properly engaged resulting in about 840 kilograms of metal spilling onto the roadway over about 30 kilometres.
The 46-year-old man was served with a future court attendance notice for driving a heavy vehicle not complying with loading requirements.
He is due to appear at Hornsby Local Court in July.
