What is the driving limit for alcohol in US?

In the United States, the legal blood alcohol concentration (BAC) limit for driving is 0.08% for most drivers. This means that if a person has a BAC of 0.08% or higher, they are considered legally intoxicated and should not drive. However, some states have lower legal limits, such as 0.05% for commercial drivers and 0.02% for underage drivers. It's important to note that even below 0.08%, driving with any amount of alcohol in your system can impair your judgment and increase the risk of a crash.
