No one likes dealing with the cops, for any sort of criminal defense or questioning, including DUI. You have responsibilities and rights, regardless of the crime being investigated. It's important to get a lawyer on your side.
You May Not Need to Show ID
Many citizens are not aware that they aren't required by law to answer all a police officer's questions, even if they have been pulled over. Even if you must show identification, you may not have to say more about anything such as your recent whereabouts and activities or what you've been drinking, in the case of a DUI investigation. Federal law protects all people and gives special protections that provide you the option to remain quiet or give only a little information. You have a right not to testify or speak against yourself, and you may usually walk away if you aren't being officially detained.
Even good guys need criminal defense lawyers. Whether you have been a drunk driver and violated other laws or not, you should take advantage of the protections available to you. State and federal laws change often, and disparate laws apply jurisdictionally. Furthermore, laws occasionally change during legislative sessions, and courts of law are constantly making further changes.
Sometimes You Should Talk to Police
It's good to know your rights, but you should think about the fact that usually the officers aren't out to hurt you. Most are good people like you, and causing an issue is most likely to hurt you in the end. You don't want to make cops feel like you hate them. This is an additional reason to hire an attorney such as the expert counsel at Criminal defense attorney Portland OR on your defense team, especially after being arrested. Your lawyer can tell you when you should volunteer information and when staying quiet is a better idea.
Know When to Grant or Deny Permission
You don't have to give permission to search through your house or car. Probable cause, defined simply, is a reasonable belief that a crime has been committed. It's less simple in practice, though. It's usually best to not give permission.
