Anything over .08 is considered legally drunk and all offenders are of equal "offense". Now, we need to look at the variables in the equation. Mainly the arresting officer and Sentencing judge.
If you blow a .11, cooperate with authorites and show up to court fairly presentable, you will likley receive something close to the minimum guilty penalty as far as fine/probation/jail time. If you blow a .24, swear at the cop, and show up at the court house smelling like Jack Daniels, you won't leave the court room without a set of cuffs and an orange jumpsuit.
