"One of our patrol cars headed off to stop the vehicle and recorded it travelling at 113km/h.
"Never mind that the legal speed limit for driving through a crash scene is 20km/h, the speed the driver was doing on the open road was too high," he said.
When stopped 4km down the road, the 51-year-old female driver returned a breath alcohol limit of 1131mcg, he said.
The legal limit for a fully licensed driver is 400mcg.
The woman was processed for third or subsequent excess breath alcohol, driving with an expired licence and speeding.
Her car was also impounded for 28 days.
The driver would appear in the Huntly District Court on December 2 but in the interim police wanted people to think about the risks on our roads, Mr Mansill said.
"Monday's incident highlights the risks posed to those first responders putting their lives on the line trying to save others.
"It is not acceptable in this age of such public awareness that people speed, regardless of the situation a speed limit is just that, a limit not a target and people caught infringing either by speeding or drink driving can expect to be held to account for their behaviour."
