Two young men who had just finished their A-level exams never made it home after a late-night snack run turned fatal when the driver of their car raced a friend’s vehicle at speeds exceeding 100mph before losing control on a rural Lincolnshire road.
Harrison Carter, 18, and George Stephenson, 17, died at the scene when the Kia Niro carrying them struck a tree on Toll Bar Road in the village of Marston on 20 June last year. The unlit road carried a 60mph speed limit and featured a warning sign for the approaching bend that the driver failed to negotiate.
Madeleine Lonsdale, now 18, had passed her driving test just 12 weeks before the crash. She was sentenced to 14 months in youth detention at Lincoln Crown Court after pleading guilty to causing the deaths of both passengers by careless driving. She was also disqualified from driving for three years.
The court heard the group had set out in the early hours to visit a petrol station off the A1 to buy snacks, alcohol and vapes. During the journey, Lonsdale and a teenage friend in a separate vehicle began racing one another, reaching speeds of 100mph. Prosecutor Steven Taylor told the court that Lonsdale then turned onto a rural country road and accelerated beyond 70mph, failing to reduce her speed as she approached a right-hand bend. The car was recorded travelling at 76mph in the seconds before the collision. The second vehicle, following closely behind, managed to avoid the crash.
Lonsdale sustained only a minor wrist injury.

The victims’ mothers addressed the court directly. Harrison Carter’s mother, Sarah Carter, described the pain of planning her son’s funeral while watching Lonsdale continue posting on social media, attend parties, and film TikTok videos in the weeks that followed. She told the court her son would never get to celebrate the exam results he had worked to achieve.
Victoria Stephenson, George’s mother, said the family missed his 18th birthday and instead attended his funeral. She told the court a skiing holiday taken by Lonsdale — which pushed back her first court appearance by two weeks — had deepened the family’s anguish.
Lonsdale’s defence barrister John McNally told the court his client understood no words or actions could undo the harm caused, and that the weight of what happened would remain with her permanently.
Lincolnshire Police Detective Sergeant Adam Doona said following the sentencing that the collision was the direct result of Lonsdale’s speed and inexperience, and called on newly licensed drivers to recognise that passing a test marks only the beginning of learning to drive safely.
