“…Despite this, however, the studies by Andreuccetti et al (2011), Nagata et al (2008), Norström (1997), and Smith (1986) showed a significant decrease in fatal alcohol-related crashes when the illegal BAC limit was lowered to below .05. The other studies that looked at reducing the BAC limit lower than .05 found no significant impact on fatal crash rates (Assum, 2010, Nakahara et al, 2013, Živković et al, 2013). Similarly, three of the four studies examining the impact of lowering the illegal BAC limit to .05 found significant decreases in alcohol-related fatal crashes after law implementation (Homel, 1994, Hingson et al, 1998, Henstridge et al, 1997) while one did not (McLean et al, 1995).…”
