what is the legal alcohol limit

The legal alcohol limit varies depending on the state and the type of driver. However, across the United States, the legal limit is 0.08% blood alcohol concentration (BAC) for regular drivers. This means that if your BAC is above this level, you are presumed intoxicated in every state. In Texas, for example, it is illegal for a person to operate a motor vehicle with a BAC of 0.08% or higher if they are 21 years of age or older. For commercial drivers, the legal limit is lower at 0.04% in Texas. Additionally, for drivers under the age of 21, it is illegal to operate a motor vehicle with any detectable amount of alcohol in their system. It is important to note that you are breaking the law as soon as drugs or alcohol affect your driving ability, regardless of your BAC.
