In Hawaii, what is the legal blood alcohol concentration (BAC) limit for drivers over 21?

  1. 0.08%

  2. 0.10%

  3. 0.05%

  4. 0.00%

The correct answer is: 0.08%

The legal blood alcohol concentration (BAC) limit for drivers over the age of 21 in Hawaii is established at 0.08%. This threshold is used to determine whether a driver is impaired and poses a risk to themselves and others on the road. It's important to adhere to this limit because exceeding it can lead to serious legal consequences, including DUI charges, fines, and potential license suspension. The limit is set to balance personal freedom with public safety; thus, individuals are encouraged to drink responsibly and understand that even small amounts of alcohol can impact driving abilities. Other options like 0.10% are higher than what is permitted, while levels like 0.05% and 0.00% reflect lower thresholds that may apply under different regulations, such as for novice drivers or commercial drivers, not the general adult population.
