The correct answer is At or above 0.08 percent. In Washington State, like most U.S. states, a blood alcohol content (BAC) of 0.08 percent or higher constitutes legal intoxication for adults aged 21 and over. This standard is based on extensive research demonstrating that at this BAC level, most individuals experience significant impairment in judgment, coordination, and reaction time, making it unsafe to operate a vehicle.
At or above 0.01 percent: This is incorrect because 0.01 percent BAC is an extremely low level of alcohol and would not typically result in significant impairment. While any alcohol can affect a person's judgment and reaction time, the legal limit is set at a level where impairment is considered substantial. This option is too low to represent legal intoxication in Washington State.
At or above 0.04 percent: While 0.04 percent BAC indicates some level of alcohol consumption, it is not the legal limit for adults in Washington State. A BAC of 0.04 percent may cause some impairment, but it is not considered legally drunk for individuals 21 and over. This option is too low to represent legal intoxication for adults. This level is more relevant to commercial drivers who have a lower legal limit.
