Final answer:
The BAC level for commercial drivers to be considered intoxicated is .04. This limit is stricter than the 0.08% for non-commercial drivers, emphasizing the serious responsibility commercial drivers hold in operating their vehicles.
Step-by-step explanation:
The new Blood Alcohol Concentration (BAC) for commercial drivers to be considered intoxicated when driving a commercial vehicle is .04. When BAC exceeds certain levels, a driver is legally deemed impaired. For commercial drivers, this level is set at 0.04% across many jurisdictions, which is lower than the 0.08% that is generally applicable to other drivers. This limit reflects the greater responsibility and potential impact of operating commercial vehicles on public safety. It is important for commercial drivers to adhere to these stricter regulations to prevent being legally charged with driving under the influence of alcohol.
