UPDATE 9.55pm: THE Werona fire is under control.
A CFA spokesman said the majority of trucks had returned home but a few units would remain overnight monitoring the fire.
He said the fire started on the side of the road and burnt into rocky, hilly countryside, burning about 100 hectares.
The fire is not being treated as suspicious at this stage.
7.15PM: Ambulance Victoria spokesman John Mullen said an ambulance was called to the scene and the three men had no obvious injuries.
"The three men are a little bit shaken up, obviously, " he said.
"One man was taken to Bendigo hospital for further assessment, but he did not have any obvious injuries.
"As far as I know the ambulance did not have any difficultly because of the terrain. We did have a helicopter on standby but it was not needed."
ONE man has been taken to hospital after a firetruck rolled in Werona, near Daylesford, as it was on the way to a 100 hectare grassfire burning nearby.
Newstead Police Leading Senior Constable Grant McDonald said the firetruck was going up Robinson Road, a dirt road, when it hit a rock that was sticking out, and rolled onto its side.
"The road is quite small and there are a lot of rocks," he said.
"At about 4.30pm the truck has clipped a rock and tipped over."
Three people were in the truck, one man has been taken to hospital as a precaution.
A State Control Centre spokesperson said the Werona fire was still burning out of control and a watch and act warning had been issued.
"No properties are under threat at this stage," she said.
"It is quite difficult terrain.
"We have 19 trucks and two water bombers at the scene."
