This study assessed whether states that lowered legal blood alcohol limits from 0.10% to 0.08% in 1993 and 1994 experienced post-law reductions in alcohol related fatal crashes.
Six states that adopted 0.08% as the legal blood alcohol limit in 1993 and 1994 were paired with six nearby states that retained a 0.10% legal standard. Within each pair, comparisons were made for the maximum equal available number of pre-law and post-law years.
States adopting 0.08% laws experienced a 6% greater post-law decline in the proportion of drivers in fatal crashes with blood alcohol levels at 0.10% or higher and a 5% greater decline in the proportion of fatal crashes that were alcohol related at 0.10% or higher.
If all states adopted the 0.08% legal blood alcohol level, 400-500 fewer traffic fatalities would occur annually.
本研究评估了在1993年和1994年将法定血液酒精含量限制从0.10%降至0.08%的州在法律实施后与酒精相关的致命撞车事故是否减少。
1993年和1994年采用0.08%作为法定血液酒精含量限制的六个州与六个保留0.10%法定标准的邻近州进行配对。在每一对中，对法律实施前和实施后最多相等的可用年份进行比较。
采用0.08%法律的州在法律实施后，血液酒精含量在0.10%或更高的致命撞车事故中驾驶员比例下降幅度高出6%，酒精含量在0.10%或更高的致命撞车事故中与酒精相关的比例下降幅度高出5%。
如果所有州都采用0.08%的法定血液酒精含量水平，每年将减少400 - 500起交通死亡事故。
