What is the legal limit for BAC while driving in most states?

1. 0.06

2. 0.08

3. 0.10

4. 0.05

The correct answer is: 0.08

The legal limit for Blood Alcohol Concentration (BAC) while driving in most states is set at 0.08%. This level has been established as a standard threshold indicating impairment because it reflects a point at which both coordination and judgment start to be significantly impaired, making driving unsafe. At a BAC of 0.08% or higher, an individual is legally presumed to be intoxicated, which makes them subject to penalties, fines, and possible imprisonment. This limit applies to most adult drivers, but it’s worth noting that different limits may exist for commercial drivers and underage drivers, who often face stricter regulations. The establishment of this standard is rooted in research showing that as BAC increases, the risk of accidents significantly rises. Therefore, it is crucial for drivers to stay at or below this legal limit to ensure safety on the road.
