The mother and baby were taken to hospital in Baie-Comeau, where the girl was pronounced dead at 5 p.m. The mother was treated for shock.
Collision investigators with the Quebec provincial police were sent to the scene. Authorities are trying to determine the sequence of events that led to the tragedy and how the mother failed to see the child.
Police expect to speak with the mother when her health permits.
