Four people, including two children, have been injured in a serious collision on the A19 in the early hours of today.
The crash involved a white car which overturned just prior to the A67 Crathorne junction at around 2.55am, coming to rest upside down in a ditch

An ambulance crew spotted the car and they called for assistance from the fire service, police and also the Highway Agency to manage the road closure.
A high-volume of traffic had to be diverted north via Stokesley throughout the morning.
The driver, a man aged in his late 40s, was taken by ambulance to James Cook Hospital in Middlesbrough for treatment.
A young boy in a rear seat was taken to the Royal Victoria Infirmary at Newcastle while a young girl, also in a rear seat, is receiving treatment at James Cook Hospital.
The front seat passenger, a 29-year-old woman, is believed to have escaped serious injury.
Police collision investigators carried out a full examination of the scene as part of ongoing enquiries to establish the circumstances surrounding the incident.
The stretch of road re-opened at 11.30am.
Witnesses to the collision or anyone who recalls seeing a white car prior to the incident, are urged to call North Yorkshire Police on 101, select option 1, and speak to the Force Control Room.
