Mexico is a country that has implemented public policies with the aim of reducing traffic accidents in drivers who have consumed alcohol, most of the country's main cities have implemented checkpoints and use of breath alcohol measurement instruments and sanctions, fines and prison for those who consume alcoholic beverages and drive. The objective of the study is to analyze the effects of public policies to prevent traffic accidents in Mexico, identifying milestones in the implementation of anti-drunk driving strategies in each of the country's states. The study design is an Ecological study, data obtained from the Global Burden of Diseases 2019, the start dates of the alcohol restriction public policy were established, in each of the states of Mexico, the incidence rates of motor vehicle accidents per 100,000 inhabitants were recorded. Our results show by 2019 at least 90.6% (29/32) of states already had permanent breath alcohol detectors in operations, only 5 of the 32 (15.6%) states were able to demonstrate a statistically significant difference (p=< 0.05) when using breath alcohol detector strategies. It was possible to identify these changes in states with at least 5 years of implementation of the public policy. The states with the longest implementation, >15 years, show contradictory growth, which may be explained by demographic changes and vehicle consumption patterns. This work is limited to the GBD 2019 data, there are several unrecognized confounding variables in the incidence of motor vehicle accidents, perhaps the states with the longest implementation time and with more contemporary implementation dates, allowed to identify a change in the incidence of accidents. The states with sufficient information and at least 5 years of implementation of the public policy on breath alcohol detectors in Mexico showed statistically significant changes in the annual incidence of accidents.
