DWI Information
In a roadside DUI case the type of test you take sometimes is critical. In your case it would not have mattered. Assume you had 4 quick drinks in a chug-a-lug. It could take a half hour for sufficient alcohol to enter your blood stream or urine and register at the 1.0 or the .08 level. But the breath test would show a higher level almost as soon as you drank the last drop.
You are lucky, as some states don't give much of a choice. Next time don't drink and drive, or if you do, call a DUI lawyer before playing lawyer yourself.
DWI Answers
The officer is supposed to give a warning of your right to remain silent and tell you that anything you say may be used against you in a court of law (your 5th Amendment rights) and that you have a right to consult an attorney, and if you can not afford one you have a right to have a lawyer appointed for you (your 6th Amendment rights) after s/he arrests you. Sometimes officers do not. The only consequence of failing to tell you is that the prosecution cannot use any of your answers to questions asked by the police after the arrest.
Of more consequence in most cases is the failure to advise you of the state's "implied consent" law, that is, your legal obligation to take a chemical test and the results if you refuse. This can impact the suspension of your license.
