Got an idea for you... when doing your reading, you might want to check out the Texas Statutes. You're dealing with a Class B Misdemeanor. Let me help you:
PENAL CODE**CHAPTER 12. PUNISHMENTS
dmcc10880, you need to follow your own advice and read the applicable statutes. I can see where you got the language that you quoted from your initial post and it comes straight off of an attorney's website that I would describe as unscrupulous and misleading. All of those extreme punishments that are listed refer to what a juvenile court can impose on a "child" (as defined in the family code) for any offense referred to juvenile court. Those extreme punishments are things that you'd see imposed for serious felony offenses like Aggravated Assault or sexual offenses. An MIC is almost never even going to be referred to juvenile court unless the juvenile is already on probation or has significant other juvenile history, and even then those extreme conditions are not going to be done on an MIC... ever... period. That website is an attorney trying to scare up some business. In any case, none of this applies to this poster because he is over the age of 17 and therefore is not a juvenile so the charge cannot be referred to juvenile court.
If you look at the actual statute then you can see that a first offense MIC is a class C offense punishable by a maximum of a $500 fine. nat2011, if you want to you can walk in there and plead to the absolute max punishment and you will pay $500 plus court costs and will have your drivers license suspended for 30 days. I would seriously doubt that such a conviction would have much impact on your recruitment for the military but I cannot guarantee anything. You can certainly speak with a recruiter and find out though. I can however confirm that a class C conviction for MIC is not going to disqualify you for military service.
It may be possible for you to receive deferred probation which would likely require that you pay a fine, perform some amount of community service and/or attend either AA or some form of alcohol awareness course. If you complete the probation successfully you will not receive a conviction and your driver's license will not be suspended.
Since this is a first offense MIC, jailtime is absolutely NOT a possible punishment.
