In Bedfordshire, Cambridgeshire and Hertfordshire last year, motorists were twice as likely to be involved in a serious or fatal collision if they had been drinking or taking drugs.
Mrs Danks, from Soham, is now an ambassador for the Road Victims Trust, a charity that supports victims of fatal and life-changing road collisions across the three counties.
She said: “Being told our daughter was dead was like dropping a bomb and blowing our lives into pieces. The pain is unimaginable and there is nothing that will fix it”.
Last year, 2,244 motorists were caught drink or drug driving across Bedfordshire, Cambridgeshire and Hertfordshire; the equivalent to one every four hours.
