A driver in her thirties died in a serious accident in Saint-Étienne-des-Grès in Mauricie on the night of Tuesday to Wednesday.
At around 2:20 a.m. emergency services were called to an accident that occurred near kilometer 207 on Highway 55 northbound in the Maskinongé MRC area.
When they arrived on scene, police found a woman in a car parked in the left lane, said the spokesman for the Sûreté du Québec (SQ).
According to initial information, the driver was in the left lane at the time of the collision with a second vehicle that was traveling in the same direction and could not have avoided him.
The victim, who appeared to have no injuries, deteriorated rapidly during transport to a hospital where he was eventually pronounced dead.
The coroner's office, which will investigate the collision, may request an autopsy and toxicology analysis, said SQ publicist Ève Brochu-Joubert.
The driver of the other vehicle was not injured but was taken to hospital for treatment of nervous shock, it said.
