The halving of alcohol-fuelled car crashes since the mid-1980s boosted US economic output by $20 billion, increased national income by $6.5 billion, and created 215,000 jobs in 2010, reveals an analysis of the economic impact of drink-driving, published online in the journal Injury Prevention.In a bid to estimate the impact of alcohol-fuelled car crashes on the US economy in 2010, the researchers calculated the economic gains (and losses) resulting from the substantial fall in this type of road traffic collision since 1984-6 and the monetary costs directly incurred by employers and consumers in 2010.
