A trailer loaded with 400 litres of sulphuric acid has been forced off the road, spilling its load onto a busy route through North Yorkshire.
A tractor pulling a trailer containing the acid crashed after apparently being forced off the road by a car on Wednesday night.
When emergency services arrived the tractor was upside down and the tank was leaking.
Fire crews diluted the acid which is extremely corrosive.
