A Petrolia woman remains in critical but stable condition in hospital following a crash just outside Blenheim.
Emergency crews were called to a single-vehicle collision late Friday night on Talbot Trail near Lagoon Road.
Chatham-Kent Police say it appears the 32-year-old driver lost control of her car and struck several trees before coming to rest just west of Lagoon.
The woman was initially taken to hospital in Chatham with life-threatening injuries, and later transferred to Windsor for further care.
The crash remains under investigation.
