FOUR people are fighting for their lives after three separate car crashes in South Yorkshire.
A 20-year-old man and a 19-year-old woman from Sheffield, a 31-year-old man from Thorpe Hesley in Rotherham, and a 17-year-old teenager from Barnsley are each in a serious condition in hospital.
The first collision occurred at around 7.20pm on Thursday, on Brightside Lane in Attercliffe, Sheffield, and left two people injured - one seriously.
A blue Porsche Boxster was travelling along Brightside Lane towards Meadowhall when, police said, it is believed to have gone through a red light before colliding with a red Ford Escort at the junction with Newhall Road.
The Escort had been travelling from Attercliffe towards Carlisle Street East. The Boxster driver - the 31-year-old man from Thorpe Hesley - has been detained at the Northern General Hospital having possibly fractured his sternum, and sustaining bruising.
His condition is described as serious.
The driver of the Escort, a 53-year-old Hillsborough woman, is also detained at the Northern General with bruising to her chest.
Around an hour-and-a-half later, at 8.45pm, another collision occurred on Gleadless Road in Sheffield.
Police said that as a blue Honda Civic car approached the junction with Buck Wood View, an animal - possibly a dog or a fox - ran into the road.
The 21-year-old male driver swerved - and ran into the path of a red Vauxhall Astra being driven in the opposite direction.
The Honda careered off the road and came to rest on a grassed area, as the animal ran off.
The driver of the vehicle suffered slight injuries - but his two passengers, a 20-year-old man and a 19-year-old woman, suffered life-threatening injuries and are both in Northern General Hospital.
The 31-year-old male driver of the Astra sustained whiplash. All those involved in the accident are from Sheffield.
And in a third crash, at 7am yesterday, a 17-year-old boy suffered life-threatening head injuries after his car hit a lorry near Grimethorpe, Barnsley, police said.
His blue Kia Picanto was travelling on the A6195 Park Spring Road when it veered across the carriageway, smashing into a Mercedes Actros LGV travelling in the opposite direction.
The Picanto rebounded, striking trees, before coming to rest facing in the direction of Shafton.
The teenager, who is from the Barnsley area, is being treated at Barnsley District General Hospital.
Police want to hear from anyone with information.
