Description: A film of road safety training for cyclists and drivers taking place in Hackney, includes shots of the first aid instruction by the St John's Ambulance staff and a Hackney Borough Council lorry. A (tarmaced?) piece of ground has been painted with white lines to lay out an imitation pattern of streets, bollards and level crossings are also added. People walk and cycle amongst this while cars, motorcycles and a red London bus move about the streets. All of this is viewed by a seated and standing audience (mainly schoolchildren). Several traffic accidents are simulated with the Police and ambulance staff seen reacting, controlling onlookers and taking the wounded person away. A water tank (marked EWS) is used to demonstrate a drowning incident. Three adult men dressed as schoolboys are floating a model yacht, one of the men falls in and the other two run away to get assistance. A group of adults rush to assist (including one acting the role of a distressed mother), two photographers snap the event while the child is pulled from the water. Further road traffic accidents are simulated involving pedestrians and cyclists (many carrying inappropriate loads such as long poles and ladders). The men dressed as boys play about a parked truck which moves off injuring one of the 'boys'. Several of the same incidents feature repeated first in colour and subsequently in black and white.
