"Sadly, emergency services arrived moments later to find two people, a woman in her 50s and her 16-year-old son, had died at the scene."
The Holden Cruze driver suffered serious injuries and was rushed to the Royal Hobart Hospital for medical treatment.
"Her son (aged in his early 20s) was a passenger in the car and was also taken to hospital with non-life-threatening injuries," Deputy Commissioner Adams continued.
It has been confirmed that the woman driving the Hilux was an off duty police officer, she was not physically injured in the incident.
The Tasmania Police Professional Standards Command attended the scene last night and will fully investigate the matter.
