New Year's Day is consistently one of the most dangerous days of the year for drivers. Not surprisingly, a unusually large percentage of car accidents tomorrow will involve alcohol -- in 2009, alcohol played a role in 40 percent of fatal crashes, as opposed to 32 the rest of the year.

But the geographic distribution of alcohol-related crashes, like their distribution across the calendar, varies widely. "A National Portrait of Drunk Driving," a map created by John Nelson at IDV Solutions' UX Blog, makes this conclusion visually obvious.
