The role of restraint omission in alcohol-related traffic fatalities

•Alcohol consumption and restraint use are negatively correlated.•Alcohol and restraint use are correlated for both vehicle drivers and occupants.•Many alcohol-related traffic fatalities can be attributed to restraint omission.

Background and aimsFatal traffic accidents affect thousands of people in the US alone every year. Alcohol consumption has been identified as a strong predictor of traffic fatalities. This result is hardly surprising as drivers who decide to consume alcohol and then drive are more likely to exhibit poor driving performance. In this paper, I argue that alcohol consumption can lead to traffic fatalities by increasing restraint omission.MethodsI analyzed individual-level data about victims (n = 488,829) of fatal traffic accidents that occurred in the US between January 1, 1999 and December 31, 2015 from the Fatality Analysis Reporting System of the National Highway Traffic and Safety Administration.ResultsThere is a strong relationship between alcohol consumption and restraint use. Both vehicle drivers and occupants are far less likely to be restrained when inebriated. Additional analyses show that part of the effect of alcohol consumption on traffic fatalities can be attributed to restraint omission.ConclusionsThere is a significant relationship between alcohol consumption and restraint omission for both drivers and occupants of vehicles that were involved in fatal traffic accidents in the US between January 1999 and December 2015. Past public health campaigns have focused on preventing traffic fatalities by persuading drivers to refrain from getting behind the wheel after consuming alcohol. My data suggest that public health campaigns should inform both drivers and occupants of vehicles about the relationship between alcohol and restraint omission in order to minimize future casualties.
