Peter and Allison Fennon, from Redcar, know only too well the devastation and finality road accidents can bring.
Their only child Kirsty died at the age of 18 after being hit by a taxi after a night out in the town.
Instead of looking forward to the day Kirsty would get married and have children, now her parents are struggling to cope without her.
Allison said: “Kirsty had everything to live for, but she was gone in an instant and our lives will never be the same again.
“She wasn’t just a daughter – she was my best friend – and I only wish I could make things different. I keep asking ‘why did this happen, why was she there, why was the driver speeding?’, but it’s too late for questions.
“We want to urge young people to stay with their friends after a night out and to always get a taxi home. We know people drink, but it’s important that they keep their wits about them and that they look out for each other.
“However, drivers also need to be responsible and must watch their speed, particularly after dark and close to pubs and clubs. If the taxi driver had been going slower in our case, maybe Kirsty would have lived.”
