People living near a Suffolk road where a mother and her three children were killed, say they had been campaigning for years for safety improvements.
Police are asking witnesses to contact them
Cortina Hamilton, 20, from Ely, Cambridgeshire, and her children died on Friday in the accident at Kenny Hill, near Mildenhall in Suffolk.
Mrs Hamilton, sons Jalin Brent, aged five, and 23-month-old Malik Hamilton, and her daughter Alyssa Hamilton, aged three, died at the scene of the crash on the A1101.
A man and a woman travelling in a Vauxhall Vectra suffered minor injuries.
Special church service
It is thought Mrs Hamilton was on her way to RAF Mildenhall, where her husband works, when the crash happened.
Local resident Kay Sallis said the local community had been devastated by the tragedy.
"We're very, very upset, more than you can imagine," she said.
"But more frustrated after so much effort has gone into the last 10 years to do something about this.
"This was an accident which was waiting to happen."
'Road safety top priority'
Suffolk County councillor Peter Monk, portfolio holder for public protection, said: "Suffolk County Council is working with the police to investigate the cause of this tragic accident.
"We can draw no conclusions until this extensive investigation is complete .
"I have already asked our officers to furnish me with data from previous accidents in the vicinity and remedial work undertaken.
"I shall also be contacting local councillors and visiting the area.
"Improving safety on our roads is a top priority for the county council."
Mrs Hamilton's husband is an aircraft maintenance engineer at RAF Mildenhall where a special service was held for the family on Sunday.
