The additional staff from Sydney will bolster a "highly-visible" road safety operation that starts at midnight tonight.

Officers will be out in force to target key safety-related offences.

Double demerit points will be in place for drivers who fail to abide by speeding and seatbelt laws for the duration of Operation Tortoise.

Sergeant Jason Bush said this year Dubbo had been lucky enough to obtain extra resources.

"Police in the Orana Local Area Command will be supported by additional staff from Sydney to give us greater coverage over the Easter period," he said.

"The message is out there that with increased resources in the area the likelihood of being detected speeding, drink-driving or without a seatbelt is even greater."

History demonstrates the need for enforcement.

Last year 39 people were detected drink-driving in the western region during the Easter period.

More than 480 people were speeding behind the wheel.

Seventy people were caught not wearing seatbelts, a figure that was up from the previous year.

More than 50 crashes were recorded on public roads in the western region, down on the previous year but police reported that more people had been injured.

No lives were lost on western region roads at Easter last year but the result for the entire state was more grim.

Three people died on NSW roads, contributing to a total of 22 fatalities across Australia.

The NSW road toll for 2014 stood at 107 at the time of going to press, 18 more deaths than for the same period in 2013.

Seventy-three of the 107 lives lost were recorded as being on country roads.

Police would also be addressing fatigue issues this Easter, Sergeant Bush said.

The operation will conclude at 11.59pm on Monday.
