A 42-year-old man is in critical condition in a London hospital following an ATV crash Wednesday night in Sarnia.
Sarnia police responded at about 10:15pm to Vidal St. S. at Clifford St. where they say a four-wheel machine had left the road.
A man was located on the scene along with the ATV.
Police continue to try to determine exactly what happened. The intersection was closed to southbound and westbound traffic into the early afternoon hours but has since re-opened.
The man was taken to local hospital and then transferred to London.
Anyone with information is asked to contact the Sarnia police traffic unit.
