Abstract: This study evaluates the impact of the mandatory drug test requirement for truck and bus drivers on traffic accidents on Brazilian highways from 2010 to 2020. Employing the difference-in-differences approach, the results reveal a significant reduction of 12.9% in accidents involving heavy vehicles on Brazilian highways. Although no statistically significant relationship was found with the mortality rate, the decline in accident rates underscores the significance of public policies aimed at enhancing traffic safety.
