Her 25-year-old brother Patrik was reportedly driving the tractor around a corner when the trailer suddenly flipped over while 14 women were standing on it.
According to reports, Jasmin hit a stone wall in her fall and was taken by helicopter to a hospital in the city of Linz in a critical condition.
Five other women were also severely injured, while seven others were treated for light injuries.
A few days after the accident, Jasmin succumbed to injuries to her head and chest.
Jasmin's niece and one of her friends are still in critical condition in hospital.
According to local media, the accident happened when Patrik had to dodge a cyclist on the road while driving too fast round the corner.
The police have started an investigation as the trailer was allegedly only fixed with one axle and was not legally roadworthy to transport people.
Jasmin's memorial service took place last Friday in the local church. She was dressed in her white bridal dress in the coffin.
Friends and family said they remember Jasmin as a loving and caring person ‘who always put the well-being of others in front of her own’.
She worked as a nurse and was active in the traditional music ensemble of the town.
The pastor said: ‘Why do we have to accompany Jasmin today on her last journey and not to her wedding?’
