Abstract
Results of a research into what drivers should know about dangerous behaviour of children in traffic and into what drivers actually know about it are presented. What they should know, was determined by investigating which are the most important traffic situations in which potentially dangerous meetings take place between drivers and children, which psychological processes in the driver and in the child can give rise to the development of accidents, and which form of internal knowledge representation drivers have of the behaviour of children in traffic and of their own driving behaviour in relation with children.
