Campainging schoolchildren from Leeds took part in a world record attempt while marching to promote road safety.
The 274 pupils from Park Spring Primary School in Bramley and 486 from Carr Manor Primary in Moortown marched from their school gates as they called for safer roads for children.
They were also attempting to break the Guinness World Record for the biggest ‘walking bus’.
The youngsters appealed to drivers to slow down to 20 miles an hour, and less, in built-up areas, to protect children like them walking on foot.
It was all part of charity Brake’s ongoing road safety campaign and its annual ‘Giant Walking Bus’ fundraising event.
This year the Giant Walking Bus involves more than 125,000 children from nearly 600 schools around the UK.
The aim is to break the record of 119,697 children taking part simultaneously, and to raise £35,000 for Brake’s work.
The money will help pay for a helpline for bereaved and injured families.
Wendy Logan, whose 10-year-old son Gordon was knocked down and killed by a speeding driver, said: “So many children are killed or horrendously injured in the UK by dangerous driving.
“I support this event to raise awareness of the importance of driving slowly in communities, and to raise funds for such an important charity that is providing vital support to road crash victims.”
The charity has found that 1,041 children are hurt every year while on foot on Yorkshire’s roads.
As well as calling on drivers to slow down, the charity is calling for widespread 20mph limits in built-up areas.
Julie Townsend, Brake’s campaign director, added: “Brake supports families whose children have been killed or maimed on roads, so we know the terrible devastation these tragedies cause.
“Yet many could be prevented. You never know when a child might make a mistake and run out. Your slower driving could save their life.”
