A man has died after a multi-vehicle crash in the state’s west overnight.

About 8.40pm on Monday 30 May, emergency services were called to the Barrier Highway at Canbelego, about 50km east of Cobar, after reports a Holden Colorado ute, a Jeep Cherokee and a road train had collided.

Officers attached to Central North Police District have been told the utility and road train were eastbound and the 4WD was westbound, when the crash occurred in the eastbound lanes. The road train subsequently left the roadway, crashed into a culvert and rolled.

Police arrived to find the driver of the ute, believed to be a 41-year-old Broken Hill man, had died at the scene.

A front-seat passenger in the ute, a 33-year-old woman, suffered broken ribs, and a six-year-old child, who was in the back seat, were taken to Cobar District Hospital for treatment.

The driver of the 4WD, a 60-year-old man from Chipping Norton, and the truck driver, a 65-year-old man from Dubbo, escaped injury and were taken to Cobar District Hospital for mandatory testing.

Police will allege the 4WD driver refused to be tested and was taken to Cobar Police Station. Inquiries are continuing.

In the aftermath of the incident, the Barrier Highway remains closed in both directions at Canbelego, with traffic diversions in place via Nymagee and Hermidale.
