With a BAC of 0.06%, how likely is an individual to be involved in a fatal crash compared to a nondrinker?

1. Half as likely

2. Twice as likely

3. Three times as likely

4. Four times as likely

The correct answer is: Twice as likely

A blood alcohol concentration (BAC) of 0.06% indicates that an individual has consumed enough alcohol to impair their judgment and coordination, albeit not to a level considered legally intoxicated in many jurisdictions. Research indicates that as BAC increases, so does the risk of being involved in a crash. At a BAC of 0.06%, the likelihood of being in a fatal crash tends to be linked to a twofold increase in risk compared to a nondrinker. This increase in risk can be attributed to diminished abilities to make safe choices and react appropriately to driving conditions, impairment in balance and coordination, and a higher tendency to take risks due to reduced inhibitions. While higher BAC levels correspond to even greater increases in risk, the data supports this specific increase in likelihood at 0.06%. Hence, it shows that the correct understanding of the impact of a BAC of 0.06% aligns with being twice as likely to be involved in a fatal crash compared to individuals who do not consume alcohol.
