The number of accidents and fatalities in traffic increases every year, with higher rates of death among young drivers who may have passed recent high school. Thinking about this relevant social issue, a comic book called "Physics in Traffic: A Life-Saving Class" was developed, which relates the laws of physics and traffic laws created on the basis of the assumptions of Significant Learning Theory (TAS) by David Ausubel and in the pedagogical practice of Paulo Freire's pedagogy, for students in the 1st year of high school. The general objectives contemplate the importance of accident prevention by assimilating knowledge and behaviors that improve the coexistence in traffic through the laws of physics, stimulating the teaching-learning process by measures that promote a critical reflection and awareness focused on attitudes and responsibilities in traffic and respect for life. The preparation of the material was based on topics of physics as Relative Velocity, Newton's Laws, Friction Force, Linear Moment and Collisions, pertinent to the subjects contemplated in the series under study and with emphasis on the physical phenomena and everyday situations in traffic. After the application of the educational product the results show that the interest and motivation of the students are renewed, when a teaching practice is achieved along with new methodology through new tools and that instigate the creativity and student participation in the teaching-learning process
