British man killed in SA crash

A man killed when a car collided with a road train in South Australia's mid-north has been identified as a British citizen.

The 26-year-old passenger died at the scene while three other people, aged 19, 24 and 25, were injured when their car collided with the truck on the Augusta Highway near Port Pirie on Monday night, police say.

The truck driver was not injured and the accident took the state's road toll to 35, on par with the same time last year.
