Possibly. The National Transportation Safety Board (NTSB) is recommending that the national per se limit of .08 be lowered to .05 in all 50 states.
"Today, investigators cited research that showed that although impairment begins with the first drink, by 0.05 BAC, most drivers experience a decline in both cognitive and visual functions, which significantly increases the risk of a serious crash. Currently, over 100 countries on six continents have BAC limits set at 0.05 or lower. The NTSB has asked all 50 states to do the same." See complete article: NTSB May 14, 2013.
