Can a person be guilty of driving under the influence in Florida if they only had one drink?
The answer is, it depends. Whether or not you’ve consumed one beverage is not going to be the ultimate test, because the question is whether you were driving impaired. It sounds like most likely if the basis for the impairment is alcohol and you have only consumed one drink, that the evidence will be insufficient to show impairment. However, nowadays we also have to make sure that there isn’t impairment from some other source. Merely having one drink may not be a lifesaver if there is something else in your system.
