A two-year-old child is currently in a critical condition following a collision in the Dodworth area of Barnsley earlier today.
Just after 2.20pm, it was reported that a grey Audi A3, travelling along Whinby Road away from the motorway, crossed on to the opposite side of the carriageway, for reasons unknown.
The Audi has then been in collision with a white Mercedes Sprinter van and a white VW Transporter van, both travelling in the opposite direction.
The collision happened between the roundabout from Higham Common Road and Barnsley Business Park.
A two-year-old girl, a passenger in the Audi, suffered a serious head injury as a result of the collision. She currently remains in hospital in a critical condition. A four-year-old boy, also a passenger in the Audi, and the driver, a 31-year-old woman, both suffered minor injuries.
A 47-year-old man travelling in the VW Transporter van was treated for minor injuries at the scene. No one else was injured in the incident.
Officers want to hear from anyone who saw what happened, in particular the driver of a HGV with a plain yellow trailer and the driver of a blue Ford KA, both travelling towards Manchester at the time of the collision.
