Two teenagers have been jailed for five years after admitting causing the death of a 17-year-old girl as they raced their cars.
Olivia Alkir, from Efenechtyd, Denbighshire, died after a two-car crash on the B5105 on 27 June.
She was a passenger in a Ford Fiesta which crashed at about 19:30 BST.
Thomas Quick, 18, from Clawddnewydd, and a 17-year-old boy from Dyffryn Clwyd, both pleaded guilty to death by dangerous driving at Mold Crown Court.
The defendants also pleaded guilty to four counts of causing serious injury by dangerous driving.
Quick was not directly involved in the collision, but was “repeatedly racing” with the 17-year-old driver, who cannot be named for legal reasons.
The 17-year-old’s car crashed with another car coming in the opposite direction between Clawddnewydd and Ruthin, leaving the passengers of the other vehicle, Dylan Jones and his mother Anwen, with serious injuries.
Judge Niclas Parry called for law changes for newly-qualified drivers to only be able to carry one passenger and have a monitoring box installed in the first year after passing their test.
Olivia was a “fun-loving, wise, ambitious individual” who was “loved by all who knew her”, her family said in a statement last year.
She was a deputy head girl and A-level student at Brynhyfryd School, where she studied physics, mathematics, geography and the Welsh Baccalaureate.
Her family said she had hoped to go on to study architectural engineering at university.
“She had a uniquely unbreakable bond with her adoring parents and was cherished by her cousins, friends, grandparents, aunts and uncles,” her family said in a statement.
“Although her life has been cut tragically short, she filled her 17 years with a lifetime of achievements.
“Olivia was beautiful inside and out and the world was a better place because of her.”
