A new Bill will be introduced in Parliament today by MP Susan Elan Jones, calling for a review of sentencing for serious driving offences that lead to death or serious injury.
It stems directly from a campaign involving the death of a nine-year-old.
Robert Gaunt from Overton, near Wrexham, was knocked down by a car on the road near his home in 2009.
The car was driven by an unlicensed and uninsured driver, who was jailed for 22 months and banned from driving for four years after he admitted perverting the course of justice.
He only served 10 months in jail.
Susan Elan Jones says she hopes the Bill will save more families from similar heartbreak in the future.
"For far too long, people who commit serious driving offences have received unduly lenient sentences. That's why we need this review."
