No one likes dealing with the cops, whether for DUI or questions in a criminals case of any kind. You have both rights and responsibilities, regardless of the kind of crime being investigated. It's almost always valuable to get a qualified criminal defense attorney on your side.
Police Can't Always Require ID
Many people are unaware that they aren't obligated to answer all police questions, even if they were driving. Even if you must show identification, you generally don't have to answer other questions cops might have about anything your plans or what you've been drinking, in the case of a DUI investigation. The law covers all people and gives specific protections that let you remain quiet or give only some information. You have a right not to incriminate yourself, and you have a right to walk away if you aren't being detained or arrested.
Even though it's important to have a thorough education about your rights, you should hire a lawyer who knows all the minutia of the law so you can protect yourself fully. Knowing all the laws and being aware of the various situations where they apply should be left up to professionals. Find someone whose first responsibility it is to know these things if you want to prevail in any crime, even a DUI.
Know When to Talk
It's wise to know your rights, but you should realize that usually the officers aren't out to hurt you. Most are good people like you, and causing disorder is most likely to trouble you in the end. You probably don't want to make police officers feel like you're against them. This is yet one more reason to get an attorney such as the expert counsel at lawyer pleasant grove on your defense team, especially after being arrested.

Know When to Grant or Deny Permission
You don't have to give permission to search through your home or automobile. Probable cause, defined in a simple way, is a reasonable belief that a crime has been perpetrated. It's less simple in practice, though. It's usually good to deny permission.
