Generally, when you make a mistake, it may have a few undesirable consequences, but you can soon move past it. However, when you make a legal mistake, the consequences can follow you throughout your life. This is especially true if you have a conviction for operating under the influence. An OUI on your record could impact your life in many negative ways. Fortunately, you may be able to expunge the conviction from your record.
Being questioned by a police officer who suspects you may be impaired while driving is no doubt something that would cause a person to be very nervous. Part of the nerves experienced in this situation is due to the fear of what consequences you might be given if you are convicted. Part of the nerves also come from a lack of understanding about the process and the tests used during the arrest.
