 If you are accused of a DUI, first of all, you're going to want to be cooperative. You don't want to get arrested simply because the officer is upset with you or you have a bad attitude. The officer doesn't like you. Obviously, so you want to be polite and cooperative. It really depends on, you know, whether you've been drinking, whether you're over the legal limit, whether you're drunk. If you're not drunk, if you've only had one or two drinks and you're fine, then you're probably okay to cooperate. As far as a breath test, if you are arrested, then they can legally ask you for a breath test. Put it to you this way. The law says you're supposed to comply with that breath test. Whether you comply or not is your decision. There are consequences, though, to not complying. If you don't comply, then your license could be suspended for a year for not complying. If you do comply and you blow over the legal limit, then you're looking at a six month license suspension. One thing that officers don't tell you, they make it sound like on a first time DUI, you don't take the breath test, you're going to automatically lose your license for a year. That is not the whole story. There's actually a process by which you can get a permit to drive on a first time DUI so that you could refuse and still continue to drive for an entire year and not lose your license for you. So it definitely gets complicated. Best bet is don't drink and drive.
