Final answer:
Penalties for a first offense DUI with a BAC of .10% or higher typically include fines, license suspension, and possible jail time, but exact consequences vary by state.
Step-by-step explanation:
The penalties for a first offense DUI (Driving Under the Influence) for someone over 21 with a BAC (Blood Alcohol Concentration) of .10% or higher vary by state, but generally include a combination of fines, license suspension, and possibly jail time. In almost all US states, a BAC of 0.08% is the legal limit for intoxication, so a BAC of 0.10% or higher is well over this threshold, which could lead to more severe penalties. Every individual metabolizes alcohol differently, so despite having the same BAC, the effects of alcohol can vary, but legal consequences are based on the BAC, not individual tolerance. Additional measures such as mandatory alcohol education, community service, and installation of an ignition interlock device may also be required.
