I just blew into the machine and it showed my BAC was over .08. Should I just plea guilty?
No! It is very unlikely you are going to gain any benefit by pleading guilty in your case. You have a constitutional right to require the State to prove that you are guilty beyond a reasonable doubt. There is nothing wrong with exercising your rights and making the State do its job. I do know that you have zero chance to win your case if you plea guilty.
