Abstract:The increased number of road accidents, leading to deaths and serious injuries is a social problem facing most of the world countries, which can affect the sustainable development of a society. This has economic implications, because it impacts the increase of expenditure on hospitalization and the recovery costs of those injured. The current article is based on a quantitative research, coordinated by the authors, conducted among traffic participants from Romania. The major objective of the study was to quantify the main aspects of seatbelt wearing behavior. The research was carried out at national level and used a systematic probabilistic sampling. The sample contains 4346 subjects, of which 3120 were from the automobile section, representing the topic of this article, and being representative of the Romanian adult population. The main research results showed that the percentage of women always wearing seatbelts (76.4%) is higher than the percentage of men (69.9%). Additionally, the highest percentage of people always wearing seatbelts is found at the age group over 55 years (85.2%). The percentage decreases with age-the age group 18-25 are the least likely to wear seatbelts.
