TRAFFIC cops want to track down witnesses of a head-on car crash which left a driver in a serious condition and put two young children in hospital.

The collision involving two cars happened on the A71 at Stonehouse at around 8.25pm on Thursday, July 13.

Cops say a black Audi A3 car was travelling west on the A71 Stonehouse Road near to Canderside Toll when the car apparently went out of control causing it to cross the eastbound lane of the carriageway and collide head-on with a black coloured Audi A4 car.

The 36-year-old driver of the Audi A3 was taken by air ambulance to the Queen Elizabeth Hospital where he is currently being treated for multiple injuries. Hospital Staff describe his condition as serious.

His 31-year-old passenger was taken to Hairmyers Hospital where he is currently being treated for his injuries which hospital staff say are not life threatening.

The 42-year-old driver of the Audi A4 and her two male passengers aged eight and five years were all taken to Wishaw General Hospital.

The driver and the five-year-old boy were released after treatment whilst the eight-year-old boy remains in hospital with a leg injury. Hospital staff say his injury is not life threatening.

Inspector Graham Conner at Motherwell Traffic Department is appealing for witnesses to the crash and anyone with information should contact officers there via 101 quoting incident number 3874 of 13 July 2017.
