Most likely you are on this page because you got a DUII charge in Oregon. We can probably point you in the right direction. If you haven't gotten a DUI, then you are here to learn how to avoid getting your drunk ass charged with driving under the influence.
No, these aren't all the best defense's against DUI, you should probably at some point contact a DUII attorney in Portland if you have actually been charged. Seriously, your drinking buddy BarFly (that's us!) is not the best source of legal advice.
