Final answer:
The risk of alcohol-related accidents or health issues increases as the BAC level rises; specifically, a BAC of 0.15% indicates a significantly higher risk compared to the legal limit of 0.08%.
Step-by-step explanation:
The risk of alcohol-related accidents or health events significantly increases with higher blood alcohol concentration (BAC). While the legal limit for intoxication typically stands at a BAC of 0.08, a BAC of 0.15 represents a much higher risk level. Critical and potentially fatal responses to alcohol, such as acute intoxication and unconsciousness, occur at even higher BAC levels of 0.20% and 0.30%, respectively. Consuming enough alcohol to reach a BAC of .15 percent drastically impairs judgment and motor skills, increasing the likelihood of injury or death. It's essential to understand the dangers associated with high BAC levels and that they vary among individuals due to factors such as age, sex, and pre-existing health conditions.
