Which two metrics are typically used to measure the effects of alcohol consumption?

BAC and NVC
BrAC and NVC
BAC and BrAC
DRC and BAC

The correct answer is: BAC and BrAC

The correct answer identifies the two common metrics used to measure the effects of alcohol consumption: Blood Alcohol Concentration (BAC) and Breath Alcohol Concentration (BrAC). BAC is a clear and quantifiable measure of the amount of alcohol present in a person's bloodstream, expressed as a percentage. This metric is crucial in law enforcement and medical settings to determine levels of intoxication and assess impairment while driving or engaging in other activities. BrAC, on the other hand, measures the amount of alcohol in a person's breath and is also used to assess levels of intoxication. Breathalyzers are commonly used by law enforcement officers to measure BrAC and provide immediate results, which can be pivotal during roadside checks and assessments of suspected impaired driving. These metrics are preferred because they provide a direct correlation to impairment levels and can inform decisions regarding safety and legal consequences effectively. Other options mentioned do not constitute widely recognized measures of alcohol's effects, thereby making BAC and BrAC the most relevant choices for this context.
