Two teenagers are dead following a single car crash in Hants County early Monday morning.

Windsor RCMP officers were on patrol at 1:35 a.m. on Highway 1 near Ardoise when a man flagged them down and alerted them of the crash.

Kevin Singer was the first at the scene. He flagged police down. He said the crash woke him up.

"It's a bad spot. It's the second or third car that's gone off the road in the same spot and there's been other numerous accidents around, right along this stretch," he said.

A preliminary investigation revealed four teenagers were inside the Chevrolet Cavalier when it left the road, clipped a power pole and ended up in the ditch.

The 19-year-old male driver and a 16-year-old girl were pronounced dead at the scene. A 19-year-old male passenger was taken to Queen Elizabeth II Health Sciences Centre in Halifax with non-life-threatening injuries.

The fourth passenger — a 16-year-old girl — was taken to Hants Community Hospital with non-life-threatening injuries. She was treated and later released.

Mount Uniacke and Brooklyn Volunteer Fire Departments and Emergency Health Services also responded to assist RCMP at the scene.

The cause of the crash is still under investigation.
