Two teenagers died when the driver lost control of his car and crashed into an oncoming vehicle.
An emotional inquest was told that friends Ryan Kirk, 19, of Denford Ash, and Charlotte Filer, 17, of Lilac Place, Kettering, were in his Citroen Saxo along the Warkton Road near Grafton Underwood, when he lost control of the car on a bend, on January 10.
The vehicle veered onto the opposite side of the road, back onto the left-hand lane, before spinning clockwise and hitting an oncoming Vauxhall Astra.
Speaking as a witness at the inquest, Louise Mortimer, who was driving the Astra, said: “I saw headlights up ahead on my side of the road, and it was snaking from one of side of the road to the other.
“I can’t remember if I had time to brake because the car was on me so quickly.
“It was only after that I heard there was a passenger as well in the car, and that is haunting.”
Ms Mortimer was 33-weeks pregnant at the time of the incident, but escaped with only minor bruising and her baby was later delivered successfully.
PC Keith Millard, forensic collision investigator, concluded that although he could not be certain, he attributed the tragedy to driver error or something that distracted Mr Kirk while driving.
He also said both drivers were driving at about 40mph.
Miss Filer was pronounced dead at the scene, while Ryan was taken to Kettering General Hospital, where he died.
Mr Kirk had no traces of alcohol or drugs in his body during the accident.
Friends and family have since organised a series of tributes for the pair.
The inquest heard Mr Kirk passed his driving test first time in June 2011 and his mum, Jayne Coales, said she always found him to be a careful driver with passengers and disliked drink drivers.
In a statement read out at the inquest, she said: “I don’t think he would have been showing off.”
Coroner Anne Pember recorded a verdict of accidental death at the inquest at Kettering Magistrates Court on Thursday last week.
Speaking after the inquest, Charlotte’s mum Jacqueline said: “I don’t blame anyone for the accident.”
