What happens if the officer believes that I have not performed the field sobriety tests satisfactorily?

You will probably be asked to take a preliminary breath test (PBT). You should be told that the only penalty if you refuse the PBT is a fine. If you fail either test you will be told that you are under arrest for driving under the influence. You will be handcuffed, searched for weapons, placed in the back of the officer's car and taken to a jail for further tests. At the jail you will be booked and held there until you post bail or until a judge releases you on your own recognizance without bail. Once again, as upsetting and as stressful as being arrested is, it is essential that you continue to act courteously and cooperatively with the officer. Do not argue, or become belligerent in any way.

This type of behavior will only make the experience even more unpleasant for you.
