Final answer:
The risk of causing a motor vehicle accident increases to 25 times greater at a BAC level of .15%. Option d) is correct.
Step-by-step explanation:
The peril of causing a motor vehicle accident rises dramatically to 25 times greater when an individual reaches a blood alcohol concentration (BAC) level of 0.15%. This level of intoxication poses a severe threat as it significantly undermines motor skills and impairs judgment, rendering driving at such a BAC highly perilous. Legal standards in most jurisdictions across the United States define intoxication at a BAC of 0.08%, making it illegal to operate a motor vehicle at or above this threshold. However, at a BAC of 0.15%, an individual is nearly twice the legal limit, amplifying the already substantial risk of causing an accident.
The stark increase in accident risk at a BAC of 0.15% underscores the profound impact of alcohol impairment on driving capabilities. At this level, the ability to navigate a vehicle safely is severely compromised, heightening the danger not only to the intoxicated driver but also to others on the road. Recognizing and addressing the hazards associated with elevated BAC levels is crucial for promoting road safety and preventing alcohol-related accidents and their potentially devastating consequences.
