酒后驾车与机动车事故和死亡率的上升有关。先前的研究表明，酒精会损害对危险行为危险性的判断;然而，酒精如何影响驾驶相关的判断尚不清楚。损伤也被证明在血液酒精浓度（BAC）曲线的各个分支上是不同的，这被称为急性耐受性。检查对酒后驾驶的危险性和驾驶意愿的看法是否在BAC曲线的上升和下降分支之间存在差异。测试感知危险的减少是否与愿意在下降肢体上驾驶有关。五十六名参与者被随机分配接受中等剂量的酒精（峰值BAC = 0.10 g%）或安慰剂。我们评估了在匹配的BAC（~0.067-0.068 g%）下，在上升和下降肢体上感知的驾驶意愿。酒精组的危险感和驾驶意愿都表现出急性耐受性。参与者认为驾驶的危险性要小得多，并且与上升肢体相比，他们更愿意在下降肢体上驾驶。感知危险的变化幅度显着预测愿意驾驶下降的肢体。与急性耐受性相关的损伤减少可能导致个体低估酒后驾驶的危险性，从而做出关于驾驶的错误决定。这项研究进一步强调了下降肢体作为一个时期的风险增加，并提供支持，以加强预防工作，针对司机在下降的BAC水平。
Drinking and driving is associated with elevated rates of motor vehicle accidents and fatalities. Previous research suggests that alcohol impairs judgments about the dangers of risky behaviors; however, how alcohol affects driving-related judgments is less clear. Impairments have also been shown to differ across limbs of the blood alcohol concentration (BAC) curve, which is known as acute tolerance. Examine whether perceptions about the dangerousness of driving after drinking and willingness to drive differed across ascending and descending limbs of the BAC curve. Test whether reductions in perceived danger were associated with willingness to drive on the descending limb. Fifty-six participants were randomly assigned to receive either a moderate dose of alcohol (peak BAC = 0.10 g%) or placebo. We assessed perceived dangerousness and willingness to drive at matched BACs (~0.067-0.068 g%) on the ascending and descending limbs. Both perceived danger and willingness to drive showed acute tolerance in the alcohol group. Participants judged driving to be significantly less dangerous and were more willing to drive on the descending limb compared to the ascending limb. The magnitude of change in perceived danger significantly predicted willingness to drive on the descending limb. Decreased impairment associated with acute tolerance may lead individuals to underestimate the dangerousness of driving after drinking and in turn make poor decisions regarding driving. This study further emphasizes the descending limb as a period of increased risk and offers support for enhancing prevention efforts by targeting drivers at declining BAC levels.
