Mudança na lei seca e mortes por acidentes de trânsito: evidências para o Brasil

Abstract

This work aims to analyze the impact of the change that occurred in law 13,546, art. 302 of the “Lei Seca”, in mortality caused by traffic accidents in the period from 2017 to 2019. The change in the law was put into effect in 2018, with the purpose of increasing the penalty for drivers who drove under the influence of alcohol. Data were extracted from SIM-DATASUS and grouped according to external causes of morbidity and mortality. Using the synthetic control method, it was shown that general mortality caused by traffic accidents was not impacted after the intervention. To analyze heterogeneous effects, the cause of treatment was analyzed by region and by weekdays and weekends, to capture the impact in different situations, however the results showed no impact caused by the intervention through the change in the “Lei Seca”.
