A horror crash between a ute and truck on a country road which sent both vehicles careening off the road has left one driver dead.

Emergency services received reports of a two-car crash on the Mid-Western Highway in Carcoar, southwest of Bathurst in NSW, about 1:25pm on Monday.

There they found the driver of the ute towing a trailed, a man aged in his 60s, dead at the scene.

The driver of a Pantech truck towing a horse float was not injured in the crash while two passengers, a boy and a girl, received minor injuries. 

The Mid-Western Highway has been closed to heavy vehicles between Mandurama and Blayney as police launch an investigation into the collision.

More to come.
