A man has died following a single vehicle crash on the D'aguilar Highway, about six kilometres north of Yarraman this morning.
Initial inquiries indicate the man's black Ford Falcon sedan left the road and collided with a large rock, before being thrown into a tree.
A passing truck driver found the car about 5.30am this morning, however it's believed the crash occurred several hours earlier.
The Forensic Crash Unit is investigating and anyone with further information or relevant dashcam footage is urged to contact police.
