What is the maximum fine for a person age 21 or older who is drinking and driving?

The maximum fine for a person age 21 or older who is convicted of drinking and driving can vary by state or jurisdiction, but it often ranges from $500 to $2,000 for a first offense. In many places, the penalties increase with subsequent offenses, which can include higher fines as well as possible jail time. Additionally, certain aggravating factors, such as a high blood alcohol concentration or the presence of minors in the vehicle, can lead to even steeper fines. Always check local laws for specific penalties.
