  1. 0.05%
  2. 0.08%
  3. 0.10%
  4. 0.12%

Answer: B — 0.08%

In Washington, the legal Blood Alcohol Concentration (BAC) limit for drivers over the age of 21 is set at 0.08%. This standard is established to ensure road safety by minimizing the effects of alcohol on driving ability. At a BAC of 0.08%, an individual's coordination, judgment, and reaction times can be significantly impaired, increasing the likelihood of accidents. The enforcement of this limit serves as a guideline for law enforcement and helps deter individuals from driving under the influence, ultimately promoting safer roadways for all users.
