Forget that the number of injuries in alcohol-related crashes from from 4,889 in 2007 to 4,511 in 2008. While the number of fatalities in those accidents rose from 243 in 2007 to 262 in 2008, an alcohol-related crash is any crash in which any person involved (drivers or passengers) consumed alcohol.
