"Forty-one% of 1,672 motorcycle operators who died in single-vehicle crashes in 2004 had BAC levels of .08 g/dl or higher. Sixty% of those killed in single-vehicle crashes on weekend nights had BAC levels of .08 g/dl or higher. (NHTSA, 2005)."
"Among drivers involved in fatal crashes, those with BAC levels of 0.08% or higher were nine times more likely to have a prior conviction for driving while impaired (DWI) than were drivers who had not consumed alcohol (NHTSA 2006)."
