Two people have died following a horror multi-vehicle crash 20km north of Dubbo.

Five cars and two trucks collided on the Newell Highway around midday where two people died at the scene.

Three people were initially trapped, including a teenager whose car was crushed under a truck, but all have since been freed.

Eight people were rushed to Dubbo Base Hospital with a total of 10 injured.

It’s believed four cars, a truck and a utility were stopped at a roadworks site when they were hit from behind by the semi-trailer who failed to stop.
