Fatal^d (unit of analysis = drivers) and Fatal^c (unit of analysis = crashes) denote prevalence estimates for fatally injured drivers (unit of analysis = driver) estimated from actual BACs for all drivers (unit of analysis = driver) in the 1997–1999 and 2004–2006 FARS and from actual BACs in each fatal crash (unit of analysis = crashes) in the 1997–1999 and 2004–2006 FARS, respectively. “N” for PDO (property damage only) and nonfatal injuries from Blomberg et al. (2005); “N” for fatal injuries from selected FARS records (selection criteria described in text).
