From what BAC range are a person's judgement and reactions impaired?

When considering the impact of Blood Alcohol Concentration (BAC) on judgment and reactions, the range of .05 to .08 is particularly significant. At a BAC of .05, some impairment begins to occur; individuals may start to experience decreased ability to track moving objects, challenges in maintaining attention, and minor impairments in judgment. As BAC approaches .08, the impairments grow more pronounced, affecting coordination, decision-making, and reaction times to a much greater extent.

This range is noteworthy because .08 is typically the legal limit for driving under the influence in many jurisdictions; therefore, it's associated with a recognized threshold for severe impairment. It's essential to understand that while impairment can begin at lower BAC levels, the .05 to .08 range is highlighted specifically because it encompasses a pivotal shift where individuals may no longer be fully competent to operate a vehicle safely.

Other ranges, like .02 to .05, may show slight impairments, but they do not reflect the level of serious concern associated with .05 and above. The higher ranges, such as .10 to .12, indicate greater degrees of impairment, but the range between .05 and .08 is critical in identifying when individuals become increasingly unfit to drive. Understanding these distinctions is
