What is the legal blood alcohol concentration (BAC) limit for drivers over 21?

• A. 0.05%
• B. 0.06%
• C. 0.07%
• D. 0.08%

Answer: (D)

The legal blood alcohol concentration (BAC) limit for drivers over 21 is set at 0.08%. This standard reflects the national guideline established by the National Highway Traffic Safety Administration (NHTSA) and is implemented in every state. At this BAC level, individuals are considered impaired, significantly hindering their ability to drive safely. The reasoning behind setting the limit at 0.08% is supported by research indicating that this level of alcohol consumption affects reaction time, coordination, and overall judgment, increasing the likelihood of accidents. Thus, adhering to this legal limit is critical for promoting road safety and reducing incidents related to drunk driving.
