How much more likely is an individual to crash with a BAC of 0.04% compared to sober driving?

An individual with a Blood Alcohol Concentration (BAC) of 0.04% is approximately 1.4 times more likely to be involved in a crash compared to someone who is sober. This statistic underscores how even low levels of alcohol can impair an individual's ability to operate a vehicle safely. At this BAC level, a person's motor skills, reaction times, and judgment can begin to be affected, increasing the likelihood of accidents.

In the context of the options provided, it is important to recognize that while the risks do increase with alcohol consumption, they may not be as dramatically elevated as they are at higher BAC levels. At concentrations closer to 0.08% or higher, the likelihood of a crash rises significantly more, which is why people often associate higher BAC with much greater risk. However, even a BAC of 0.04% can still lead to a noticeable increase in risk, emphasizing the importance of responsible drinking and understanding the dangers associated with driving under the influence of any amount of alcohol.
