Trends In Alcohol Related Fatal Traffic Crashes United States PDF Download

This is the 21st annual surveillance report from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) on trends in alcohol-related fatal traffic crashes. Data in this series of reports are compiled by the Alcohol Epidemiologic Data System (AEDS) from sources provided by the National Highway Traffic Safety Administration (NHTSA), the Federal Highway Administration (FHA), and the U.S. Census Bureau. Beginning with the current report, AEDS implemented major methodological changes in determining alcohol involvement of fatal traffic crashes. This includes using imputed data on blood alcohol concentration (BAC) for drivers who were not tested for BAC or whose test results are unknown. The imputed BAC data are provided by NHTSA for 1982 and later years. In order to present consistent trend data, AEDS recalculated all historical numbers with the imputed BAC data and excluded data before 1982 from this report. As a result, the proportion of alcohol-related traffic crash fatalities as well as the proportion of drivers alcohol involvement in these crashes increased substantially from data presented in the previous issues of this report.
