In Idaho, drivers who are under the legal drinking age (21 years old) are prohibited from operating a vehicle with a blood alcohol concentration (BAC) of .02% or more. However, the penalties for an underage DUI violation are different than those for a standard DUI.
An underage DUI is a misdemeanor and carries the following penalties:
For all offenses, the driver must complete a substance abuse evaluation and possibly some sort of education or treatment.
Underage drivers who are caught operating a vehicle with a BAC of .08% or more or while under the influence of (impaired by) drugs or alcohol face the standard DUI penalties. Depending on the circumstances, someone convicted of a standard DUI could be looking at fines, jail time, and license suspension.
Regardless of the charge, it's always best to talk to an experienced DUI attorney if you've been cited for driving under the influence. A qualified lawyer can tell you how the law applies to your situation and help you decide on the best course of action.
