Sara-Louise Scott was described by her family as a "bubbly, fun-loving, beautiful girl" after she died after a crash on the A92 near Freuchie in Fife on Friday.
Ms Scott, from St Andrews, was the passenger in a blue Seat Ibiza that overturned at about 8pm. She died in hospital that evening.
Her distraught relatives yesterday said in a statement released through the police: "Sara-Louise Scott was a much loved daughter, granddaughter, sister, partner, niece and friend.
"Her family are devastated at this time and will desperately miss the bubbly, fun-loving, beautiful girl Sara was. She will be missed by everyone who knew and loved her."
Friends also posted tributes on Sara's Facebook page. Siobhan Dunn wrote: "I can't believe you have gone so soon. I'm going to miss all the good times we had together. Missing you millions, you will always have a place in my heart and soul."
Paul Robertson wrote: "Major shock to my system - rest in peace Sara-Louise Scott, my thoughts are with all family and friends."
Samantha Macintyre added: "My thoughts are with Sara-Louise Scott's family and friends. Taken away far too young. You will be missed by everyone."
Ms Scott leaves behind mother, Louise Reilly, and father Kevin Scott, as well as siblings Chloe, Declan and Stephen.
Her boyfriend, Jamie Murray, lives in nearby Ladybank.
The road near the accident scene was closed for eight hours after the crash while police carried out investigations. The man driving the car suffered minor injuries.
Fife Constabulary says it was continuing to investigate the circumstances surrounding the accident and was keen to speak to anybody who may have seen the vehicle before or at the time of the accident.
Local residents claim the road where the crash happened is an accident blackspot.
Colin Nikolic, secretary of the Glenrothes Area Futures Group, said: "Agencies including the police, Fife Safety Camera Partnership, Transport Scotland and others all accept the road needs action, but the council ignores this issue despite the deep anger and resentment in the community."
