Police were called to the scene at about 6.45pm yesterday on the Warrego Highway, near the Laidley Creek Bridge at Glenore Grove.
Initial investigations suggest the previous night, at about 8.30pm, a white Toyota Landcruiser travelling east along the highway left the road and crashed.
The driver and sole occupant, a 67-year-old Regency Downs man, got out of the car before dying from his injuries.
His body was found a short distance from the Landcruiser.
Any witnesses or anybody with dashcam footage is urged to contact police.
