More than 10,000 children from across the East of England have taken part in a special 'Kids walk' organised by the road safety charity Brake.
Schools from across the UK have been invited to take their children out for a walk to teach them about staying safe by the roadside.
Watch a report by ITV News Anglia's Emily Knight.
Icknield Primary School in Sawston near Cambridge took part in the 'Kids walk' and also invited the police to talk to the children in reception and year one about road and cycle safety.
Other short, supervised walks have taken place in and around schools and nurseries across the UK.
Children have been walking in a crocodile formation and holding hands to highlight the importance of being able to walk without fear or threat from traffic.
Brake wants to see five measures in place to improve road safety:
- Better access to footpaths
- Cycle paths
- Safe places to cross the road
- Slow traffic
- Clean traffic
