By the number of the deceased in traffic accidents, Slovenia belongs to the less safe countries of the European Union. In case of a traffic accident with injured people, first aid can prevent worsening of the condition, handicap or death of the affected persons. In order to provide immediate first aid, a first aid kit is a necessary and compulsory safety item in all motor vehicles. The purpose of the research was to determine whether motor vehicles are equipped with the necessary (old or new) first aid kit and whether motor vehicle drivers are familiar with the contents of the first aid kit and maintain it properly.
