If your blood alcohol level is .04, how much more likely are you to crash compared to a person without any alcohol?

A blood alcohol concentration (BAC) of .04 denotes a significant impairment, even though it is below the legal limit for driving in many places. Research indicates that individuals with this level of alcohol in their system are indeed at an increased risk for accidents. Specifically, studies show that a BAC of .04 can increase a driver's likelihood of crashing by anywhere from 2 to 7 times compared to someone who has not consumed any alcohol.

This increased risk can be attributed to a variety of factors, including reduced reaction times, impaired judgment, and decreased coordination. It’s crucial to acknowledge that the effects of alcohol can vary widely between individuals based on factors like body weight, tolerance, and overall health, but statistically, the general consensus aligns with the range mentioned.

The other options suggested a higher or narrower range of increased risk, which do not accurately reflect the findings of studies regarding alcohol consumption and driving safety. Therefore, the answer indicating a 2 to 7 times greater risk is grounded in empirical research related to the effects of a BAC of .04, making it the most accurate reflection of the potential dangers of driving under the influence of this level of alcohol.
