If you are stopped for DUI, how long do they have before they charge you with a crime?

With exceptions the statute of limitations pertaining to DUI/DWI in Minnesota is three years. In some circumstances the statute of limitations may be 'tolled' (delayed, prolonged, stopped from running), typically for a determinate length of time.  Certain limited circumstances can give rise to there being no statute of limitations.  In my legal work as a criminal defense attorney it is not uncommon for me to confer privately with a person who is concerned, worried, he/she may possibly be charged with some criminal offense or offenses.  This is known as 'pre-charge' legal assistance or representation. In the event that you or a loved one are worried or concerned about a possible criminal charge, I urge you immediately to confer with a criminal defense attorney.  I recommend that you make several phone calls in choosing an attorney, because it is critically important that you feel a sense of great safety and trust in the attorney you choose to help you. Based upon my professional experience, the sooner a client contacts me and confers with me, the more effectively I can assist the client.
