The purpose of this study was to determine the Blood (breath) Alcohol Concentration (BrAC) rates of college football fans on game day. Researchers employed a time-series study design, collecting data at home football games at a large university in the Midwest. Participants included 536 individuals (64.4% male) ages 18-83 (M = 28.44, SD = 12.32). Approximately 90% (n = 482) of the sample indicated consumption of alcohol. The average BrAC for the entire sample was 0.061 mL/L (SD = 0.044). Results demonstrate the majority of college football fans consume alcohol while tailgating on campus. Various ways to minimize alcohol consumption exist including limiting the number of areas where drinking is permitted on game day. Participants appear to support these measures if alcohol consumption is legal in select tailgating areas. (Contains 1 table and 3 figures.)
