Abstract
Objective: To analyze traffic mortality in the state of Maranhão and the impacts of implementing Law No. 11,705 / 2008, popularly known as "Dry Law." Methods: Data from death certificates from 2005 to 2017 were obtained on a platform digital on DATASUS of the Ministry of Health and worked in the Microsoft Excel program, with the deaths being divided into groups. Results: Traffic mortality represented about 4.50% of the deaths in the period. Much of this percentage was of young adults, however, when compared per 100,000 inhabitants, the elderly make up the majority. The male sex had the highest mortality, about 82.90% of deaths from traffic accidents. The group "motorcyclists" showed the highest increase in mortality during the study period. Conclusion: A decrease in mortality was noticed in the year after the implementation of Law No. 11,705 / 2008 and in the years when there were changes in it, improving inspection and increasing awareness actions on Prohibition can result in declines in the mortality rate due to traffic accidents.
