The mother of a medical student killed by a hit-and-run driver last night spoke of her "relief" after the Court of Appeal doubled his prison sentence and banned him from driving for ten years.
Three judges in London ruled that the original 18-month term handed down to Jaswinder Singh (46) of Ward End, Birmingham, was "unduly lenient".
Abigail Craen, aged 20, originally from Liss, Hampshire, was only five weeks into her course at Birmingham University when she was hit on a pelican crossing in the city in 2005.
She was thrown nearly 100ft by the impact and suffered irreversible brain injuries. She died the next day.
Singh pleaded guilty to causing death by dangerous driving, failing to stop after an accident, failing to report an accident and driving without insurance.
As well as the jail term, he was banned from driving for four years at Birmingham Crown Court in April, when it emerged he had only just had his licence back following a 12-month disqualification for drink driving.
The four-year ban was increased to ten years by Lord Justice Latham, sitting with Mr Justice Forbes and Mr Justice Irwin.
Singh, who was travelling over the speed limit when he hit Abigail and then hid his car in a garage before going to the police seven days later, had waived his right to be present in court for the proceedings.
After the hearing, the victim's mother Susan Craen, who had described the original sentence as an "insult" to her daughter, said: "It's a relief that it has been taken seriously, and this was the best we could have hoped for although it doesn't in any way reflect our loss.
"We are very relieved that the ban has been increased to ten years which, in a way, has always been more critical to us than the prison sentence.
"But I still feel very strongly that anyone involved in a hitand-run accident - lethal or otherwise - should automatically and immediately have their licence removed for life."
The judges increased the prison term after agreeing with submissions made on behalf of the Solicitor General Mike O'Brien that the 18-month term for causing death by dangerous driving was unduly lenient.
It was argued that it failed to reflect the gravity of the offending, the need to deter others and the public concern about road safety.
Giving the ruling, Lord Justice Latham said: "In our judgment this offender should have expected a sentence of five to six years' imprisonment before consideration was given to his plea of guilty."
He added that in those circumstances and bearing in mind the element of double jeopardy - where a defendant faces sentencing twice - "the right sentence for us to impose today is one of three years' imprisonment".
If the original sentence had stood it could have seen him released in August because of time served on remand.
The appeal judges directed yesterday that the 145 days he had spent on remand should be counted towards his sentence.
Lord Justice Latham said it was a "tragic event" which resulted in Abigail's death, adding: "We have before us the evidence of the devastation that the offence has caused to her family."
Roger Vincent, spokesman for the Royal Society for the Prevention of Accidents, welcomed the decision.
He said: "We felt the original court's decision was totally inadequate and was sending out the wrong message to drivers who behave irresponsibly and dangerously on our roads. This was an example of dreadful driving which had appalling consequences. Motorists who disregard the law need to understand such behaviour will not be tolerated."
