A Scotch Village man has been charged with impaired driving after a crash in Mount Uniacke.

The 75-year-old was arrested after he refused to give a breath sample following the collision Thursday morning.

RCMP say he was driving a truck, and allegedly rear-ended another car on Highway 1, pushing it into oncoming traffic.

That caused a head-on collision with another car.

Multiple people were hurt, a 72-year-old woman in the car that was rear-ended suffered life-threatening injuries.

A passenger in the truck had serious injuries, three others sustained minor injuries.
