The condition of a Palmerston woman was upgraded to 'stable' Thursday after she suffered major injuries in a two-vehicle crash Wednesday afternoon.
The 52-year-old woman was the driver of a car that was in a collision with a transport truck at the intersection in the hamlet of Parker in Mapleton Township.
Two family members were with her in the car. A 29-year-old woman and a 1-year-old boy suffered non-life threatening injuries. They are also from Palmerston.
The transport driver was not injured.
Members of the Wellington County OPP and Technical Collision Investigators continue to investigate.
