A particularly vulnerable group of road users are children, who are often not focused on traffic events due to play and speed. The cause is the psychological and physical factors of growth and development of the child, which is why adult road users must pay special attention to children and take into account that children's behavior in traffic is quite different from the behavior of adults. In order to increase the safety of children in traffic, it is necessary to teach children the basics of traffic and safety rules from an early age. It is necessary to explain and present possible dangerous situations in traffic, in such a way that the child can understand the dangers of the situation and react in an appropriate and acceptable way. Nowadays, the most frequent transport of children is by car and school bus. Adherence to legislation and proper placement of children in vehicles increases the safety of children in traffic and reduces the consequences of accidents. Traffic safety depends solely on the behavior of road users.
