The man was not injured in the accident however the cow died and was moved off the road by a passer by.

Imbil police sergeant Bill Greer said a second car came along directly after and swerved to avoid the accident, but crashed into a guard rail on the bridge.

The driver of the second car was also uninjured.

A QAS media spokesperson said an ambulance came across the incident while on the way to hospital with another patient at 6:41am and police, firefighters and ambulance crews were called to the scene.

"Fortunately no one was injured in the accident but the beast was deceased," Sgt Greer said.

"This could have been a lot worse, there could have been a fatality.

"Stock move this time of year and it's probably going to get worse over the coming months.

"We ask farmers be aware of your fences, be aware of your stock."
