Although moderate drinking does not necessarily increase a person's blood alcohol concentration (BAC) to the level at which driving is legally prohibited in the United States, any drinking can impair driving tasks. In addition to laws establishing lower legal BAC limits for drivers, legislative approaches for reducing alcohol-impaired driving include imposing sanctions for drinking and driving and restricting alcohol's availability.
虽然适度饮酒不一定会使人的血液酒精浓度（BAC）升高到美国法律禁止驾驶的水平，但任何饮酒行为都会损害驾驶能力。除了制定更低的驾驶员法定BAC限值的法律外，减少酒后驾车的立法措施还包括对酒后驾车实施制裁以及限制酒精的供应。
