No lawyer can tell you your chances because there are many variables. However, some of the issues that may matter could include: your BAC and how close it is to the .15 cutoff, any issues with the tests that were given, any lack of bad driving, etc. Police don't have to read your rights to you before administering the FST tests so I don't know if that is an actual problem, however, it is certainly something that must be investigated. You should definately consult with an attorney so that more information can be gathered. If you would like a free consult with our office, please give us a call or email.
No attorney can tell you what your chances are at reducing your case without looking at the facts of the case first. The facts in the police report will allow an attorney to review the facts in order to determine whether or not your particular case can be reduced.
As for the admission of rights (Miranda rights), generally, a police officer does not have to read you your Miranda rights when conducting a DUI investigation. However, there are exceptions to this and in order to determine whether your Miranda rights were violated you need to contact an attorney.
There are countless possibilities as to what an attorney can do. Mr. Fish is correct in that your "chances" are better in getting an extreme down to a non-extreme DUI if the blood-alcohol content is close to .15, or if there are other things that happened (or didn't happen), such as: did the police follow correct procedure in conducting the breath or blood test(s)? what was the reason for the stop in the first place? did you ask to speak to an attorney and were denied that request by the officer?
The bottom line: you need to speak to an experienced criminal defense attorney, such as myself, to discuss your case, and your options, in greater detail than can be done in this setting.
