It is customary for a first arrest on a non-violent
misdmeanor not to have to sit in jail to wait for his first court date unless something about him indicates that he's a flight risk. You clearly are not.
You have not been found guilty of this offense yet, so all of the penalties except the impoundment are yet to come. The choice between jail and community service would be yours.
I can't predict the fine nor can I predict what a lawyer can do for you. So much depends upon the facts and circumstances of a particular offense, the legality of the initial stop, the accuracy and of the breathalyzer, and so on. I can say, however, that given the high BAC count, the state will probably not start out overly generous. A year is the maximum period of suspension.
90 days is the the usual for a first conviction on this, but again it will depend upon the facts and circumstances. If this is pretty garden variety, 90 days is likely. If there was an accident involving injury or property damage, the penalties can go up.
Lawyers charge clients based on the amount of time they think they will have to spend on a case. And the average lawyer bills out his time at $200-$300/hour or more. If your case is to be a negotiated disposition, It will be substantially cheaper than if you have to appear repeatedly to fight the charges. A trial
case even on a misdmeanor level can cost a couple thousand dollars.
YOu can get a more accurate ballpark figure by contacting the Connecticut Bar Association's Legal Referral Service.
If you were interested in having them find a lawyer also, they charge around $50 for the referral which includes a half-hour consultation with the lawyer.
