A man has been found dead inside a car on the side of Mathinna Road.
Emergency crews were called to the scene on Thursday afternoon, after another driver noticed the car off the road.
After they called triple zero Tasmania Police, SES, and firefighters all arrived, but the driver was already dead.
Crash scene investigators were then called to the scene, and police were trying to determine when and how the man had crashed.

Police said the 66-year-old driver was from Mathinna.
No other vehicles were involved, and the man's next of kin was notified on Thursday evening.
