A mother whose 11-year-old daughter died when exiting her school bus has called for better road safety in Northern Ireland.
Caitlin-Rose McMullan died after being hit by a car in Castledawson, County Londonderry, in March.
Stella McMullan said her daughter may not have lost her life if there had been "bus safety in place".
It comes as plans are in place to bring forward legislation to prohibit drivers overtaking school buses which have stopped to drop off or pick up their passengers.
Ms McMullan said Caitlin-Rose was "blindsided" when she walked out between two buses and "couldn't see traffic coming".
"My daughter unfortunately died on a 60mph road with no footpath, with no bus shelter and basically got off her bus on a mucky, grass verge – so the bus pass that she [was] issued, I thought was a death sentence," she said.
Ms McMullan was speaking at Stormont where other families who lost loved ones in similar circumstances also shared their support for any legislation to tighten road safety laws.
'It's about saving kids' lives'
Calls have been made for new laws to improve school bus safety in Northern Ireland since Caitlin-Rose's death.
Ms McMullan said there are "no words to describe" how poor the safety around the bus stop was.
She said she's working with the infrastructure minister "to get bus safety out there", and added that: "It's about saving kids' lives."
"I just felt that I had to reach out and do something, because it's not like this isn't going to happen again. It's when will this happen again," she said.
Overtaking school buses
There are plans to bring forward legislation to prohibit drivers overtaking school buses which have stopped to drop off or pick up their passengers.
Infrastructure Minister Liz Kimmins said "tragic events" have highlighted the safety of children getting on or off school buses.
"I believe strengthening the law around this issue is an important step in further improving safety for children here," she said.
The St Pius X College, Magherafelt, pupil was described by her school as being "a very popular pupil who was always smiling".
Currently in Northern Ireland there is no legal requirement for other vehicles to stop when a school bus is picking up or dropping off pupils.
In some parts of the United States and Canada, it is a motoring offence to overtake a school bus when it has stopped.
Safety measures in these jurisdictions include retractable stop signs on the left-hand side of buses which flashes amber or red when children are exiting.
Similarly in Germany, drivers cannot overtake a school bus while it is letting passengers on or of, this is usually identified by red flashing lights.
Kimmins, who announced her intention to bring the legislation forward, said she has asked her department officials to "explore the issue".
"Too many families have had their world shattered by receiving the worst possible news after a loved one has set out on a routine journey," she said.
"I have met grieving families and heard their heart breaking stories. I am committing to introducing legislation to help prevent more lives being devastated."
'Tragic death of Caitlin-Rose'
The Social Democratic and Labour Party (SDLP) MLA Patsy McGlone said it's important to improve road safety for children in memory of Caitlin-Rose.
"Everyday across Mid Ulster and across the north, cars speed past school buses, gambling with children's lives," he said.
"The tragic death of Caitlin-Rose McMullan in March has seen a young life cut far too short, devastating her family and our community, and we as legislators need to do everything we can to prevent this from happening again."
Democratic Unionist Party MLA Deborah Erskine said the possible legislation is a "vital step in protecting our children as they travel to and from school".
"Far too often, we have seen reckless behaviour around school buses that puts young lives at risk," she said.
"Families have been left heartbroken by the loss of children."
Issue first raised over 20 years ago
It is now more than 20 years since a motion came before Northern Ireland's Assembly asking for an urgent investigation into how children could be better protected getting on and off school buses.
The 2002 motion came just months after the death of 14-year-old Julie Louise Meldrum from Kesh, County Fermanagh.
The teenager had been knocked down as she got off the bus outside her home in December 2001.
The assembly motion had been brought forward by then Ulster Unionist MLA Danny Kennedy.
He said in 2001, about 300 school children had been injured travelling to and from school.
Patricia Lewsley-Mooney, then an SDLP MLA who would later become the children's commissioner in Northern Ireland, remembers that was among a number of road safety improvements discussed.
It is a move that "still makes perfect sense", she told BBC News NI, and one that would also need other drivers to comply with the required law changes.
"Back then it was decided we would go down a different route, we would put better red warning lights on the back of buses."
That more than 20 years later there are still safety improvement calls, she said, is disappointing.
