Background: Prevention is one of the main therapeutic weapons in trauma. Within the Andalusian Accident Plan, there is a specific line of work dedicated to it. Its star measure is the “Project on Wheels” aimed at adolescents, the main risk group: young people between 15 years and 24 years of age, male gender. Our objective is to carry out a descriptive and results analysis of this preventive action from its implementation to the present day. Study design: An analysis of the project has been carried out since its implementation in 2009, analyzing the number of events developed, population it has reached, and the results that it entails in terms of accident reduction and type of injuries (deceased, minor injuries, and serious injuries). Results: During this period (2009–2018), there have been more than 150 events with a population impact of more than 600,000 people. The “Road Show” has reached more than 100,000 teenagers. Almost all events are focused on the prevention of traffic accidents, the main mechanism of injury in this population group. Performing a comparative analysis between the data prior to the plan and later, the number of deaths has fallen by 53%, the seriously injured by 60%, and the mild by 16%. In this population group, the mortality rate drops by 66%, being the highest of all the groups analyzed. Conclusion: Prevention plays a key role, being necessary a special attention to the population groups at risk and an adaptation to their peculiarities. Although up to now, the effectiveness of these has been demonstrated, we must insist on this aspect, as well as others (training, assistance, research, and management), with the aim of minimizing injuries secondary to accidents
