Police in Halifax are investigating two crashes Wednesday morning on Highway 102 in Halifax, one of which claimed the life of a 57-year-old man.

According to Halifax Regional Police, shortly after 7 a.m. a tractor-trailer left the road and entered the ditch. The driver, the only person in the truck, was unconscious when police arrived.

He was transported to hospital by EHS and later died.

The second crash, shortly after 9 a.m., involved a pickup truck hitting a Halifax Regional Police motorcycle, which was assigned to an officer providing traffic control after the first crash.

Police said the driver of the truck was treated for non-life-threatening injuries.
