A motorist has become Perthshire's sixth road accident victim in two days.
Bill, Allison and William Melville died in the crash on the A85
The accident, involving a man in his 50s, happened on the A9 at the western turn-off into Auchterarder, when his Vauxhall car collided with a Honda.
The incident took place at about 0730 GMT and followed the deaths of five other people in one accident in Perthshire on Saturday evening.
Police named two women who died in the A85 crash as Donna Miller and Tanya Webster, both 19 and from Crieff.
They were passengers in a Vauxhall Corsa which collided head-on with a Honda Civic on the road, near Methven, before it overturned and caught fire.
The incident also claimed the lives of Allison Melville, 60, her husband William, 67, and her son, also called William, who was 33.
Tayside Police revealed how they battled to save the occupants of the Corsa.
The young driver, from Auchterarder, was taken by ambulance to Ninewells Hospital in Dundee where he underwent emergency surgery to serious burns on both of his legs.
He was also treated for a fractured left arm and a facial injury. His injuries were not thought to be life-threatening.
The car was quickly engulfed by flames and the two passengers could not be rescued.
Christine Ross, headteacher of Crieff High School, formerly attended by Ms Miller and Ms Webster, said people had been shocked by the deaths.
"Tanya and Donna were very bright and popular young women," she said.
"They had everything to look forward to and a great deal to offer. The thoughts of the whole school community are with their families."
Donna Miller and Tanya Webster also died in the crash
The Melvilles' home community of Methven has also been in mourning following the deaths.
Resident Adrian Ferguson said of Mrs Melville, a school crossing attendant who was made an MBE in 2002: "She was dedicated to road safety, helping children every day crossing this busy road.
"What a tragedy all lives were taken just a few miles from home and safety."
A special assembly was held at Methven Primary School with local minister, the Reverend Brian Bain.
Headteacher Linda Findlay said: "The school community and the wider community are devastated by the loss of Allison and her family.
"Not only was she a lollipop lady at the school, she was also a Guider and took a karate class in the village, so she was very well-known to the children."
The man who died in the Auchterarder turn-off crash has yet to be named and the driver of the other car was taken to Perth Royal Infirmary with what were thought to be minor injuries.
The accident forced the closure of the busy A9, with traffic being diverted through Auchterarder.
