A 90-year-old woman is dead after a head-on collision in Saint-Eustache Thursday night.

The woman was the passenger in a car when it collided with another vehicle that was making a right turn on Arthur-Sauve Blvd. to get into the Saint-Eustache Autodrome.

The driver of her car, an elderly man, was seriously injured and remains in critical condition in hospital.

The condition of the driver of the other vehicle is so far unclear.

Saint-Eustache police are investigating. They don’t believe alcohol was a factor.
