Final answer:
In Washington State, the legal limit for blood alcohol content while driving is 0.08 or above. This standard is set in line with the majority of US states and is enforced to prevent impaired driving and ensure road safety.Option 2 is the correct answer.
Step-by-step explanation:
In Washington State, you can be arrested for driving with a blood alcohol content (BAC) of 0.08 or above. This is because a BAC of 0.08% by volume is considered legally consumed alcohol in almost all US states, according to the consensus on the legal limit for intoxication. Driving with a BAC at or above this level is a serious offense, given the impaired judgment and motor skills associated with such a level of intoxication.
The regulation comes in the context of the National Minimum Drinking Age Act of 1984, which required states to adhere to the minimum drinking age of twenty-one or risk losing federal highway funds. This act played a significant role in creating uniformity in the legal response to alcohol consumption and driving across the United States. Breathalyzer devices are commonly used to measure BAC, and they rely on the oxidation of ethanol to indicate the level of alcohol in the bloodstream.
