Police stopped a stock truck east of Dubbo on June 4 after observing an issue with the rear doors.

"They observed a rear door on the trailer open, exposing the stock to a risk of falling from the vehicle," NSW Police State Rural Crime Co-ordinator Detective Inspector Cameron Whiteside said.

"We were working on a report that one [sheep] fell out and died and one was injured."

Det Insp Whiteside said the open doors had "exposed both decks of sheep from falling out of the truck".

Officers will allege that the 57-year-old female driver from Tooraweenah did not hold a driver's licence for this type of vehicle and did not hold the correct permits for stock transport.

Det Insp Whiteside said it was a very challenging incident for officers to attempt to pull over the truck without using lights and sirens for fear it would spook the sheep and cause more to fall out of the moving vehicle.

The merino sheep were being transported from Elong Elong to the Dunedoo sale yards.
