A 29-year-old woman is dead after a crash on Highway 16, between Prince George and Vanderhoof, Friday afternoon. 

Police say Jennifer Joseph, a mother of three from Fort St. James, was a passenger in a vehicle that lost control and crossed the centre line, colliding head-on with another car.

Cpl. Madonna Saunderson with Prince George RCMP said treacherous road conditions could be a factor in the crash.

"We're into winter driving of course, it is December, and weather conditions and road conditions can change instantly, especially when storms blow through and with the conditions that we've had in the past 24 hours here in the Prince George area with rain — it makes already slippery roads even more treacherous," Saunderson said.

"People need to slow down, have good winter tires on their vehicle and drive according to the conditions."

The driver of the car, a 28-year-old woman also from Fort St. James, along with two passengers — a nine-year-old girl and two-month-old infant — were taken to St. John Hospital in Vanderhoof with non-life threatening injuries.

The four occupants of the other car were taken to University Hospital of Northern British Columbia Hospital in Prince George, where they were treated for minor injuries.
