Three passengers are dead following a single-vehicle crash at Tarago, about 30km north of Bungendore, on Sunday afternoon.

The driver, a man aged in his 20s, was able to get out of the vehicle unassisted and has been taken to Canberra Hospital with minor injuries. He will also undergo mandatory blood tests.

NSW Police say emergency services were called to the intersection of Bungendore and Collector roads at Tarago after reports a vehicle left the road and rolled. Three passengers – a man and two women – were trapped in the car and died at the scene.

Bungendore Road is closed (as at 6.30pm Sunday) between Collector Road and the Kings Highway, and north to the Tarago township. The road is likely to be closed for some hours and police advise motorists to delay their travel if possible or find an alternate route.
