UPDATE: Two men taken to hospital after truck rollover
4.05PM: THE TWO men involved in the truck rollover this afternoon on the Dawson Hwy have been taken to Gladstone Hospital for observation.
Traffic diverted around the crash this afternoon for a short period, however all emergency vehicles have since left the scene and the highway is open as normal.
12:30PM: TWO MALES who were in the truck which rolled on the Dawson Hwy just before midday have escaped serious injury.
Police were called to the scene of the crash at 11.55am and are still in attendance.
The truck is on its side and "taking up some room on the highway", according to a Queensland Fire and Emergency Services spokeswoman.
One fire crew is also on scene, while others who were on their way have been re-directed from the job - meaning it is unlikely the truck contains any potentially hazardous cargo.
