Meanwhile, the region's police officers have made a plea following a high number of fatalities on Western NSW roads so far this year.

Western Region Traffic Tactician Inspector Ben Macfarlane said a number of single-vehicle and off-road accidents had featured among the region's fatalities.

"They could be fatigue or driver distraction, it's a concern," he said.

"We're still getting that percentage who weren't wearing their seatbelts when they crashed."

Two separate stints of double demerit points apply for motorists, these run from April 18-22, and then April 24-28. The period applies from midnight on the start date to midnight on the finish date.
