Answer:  I'm sure that many people ask themselves the same questions.  You should get the best lawyer you can afford to represent you and do it as soon as possible, since your license may be suspended if you do not ask for a hearing within ten business days from the date of your arrest.   I would not represent myself if I were to be arrested for DUI as there are things a lawyer can do for you that you can not do for yourself, and if you try to do things for yourself, remember that everything you say will be used against you.  The old saying, "a person who represents himself has a fool for a client", comes to mind and it is true.

Answer: You are assuming that you know the law and whether or not the officer did everything that he should have done when arresting you. The most important thing to remember is that the burden of proof is on the state, not you. An experienced DUI attorney can review your case and determine whether or not you have a good defense and if the state can prove its case beyond a reasonable doubt. There are strict legal requirements that the state must meet in order to prove you guilty. Don't make the mistake of assuming that they can do it all. There are some very good legal challenges to field sobriety tests and breath testing equipment. A good DUI lawyer will know these and be able to help you defend your case.
