A DUI arrest, just like an arrest for any other offense, must be based on probable cause. If the officer arrests you for a DUI in Columbus, it is their belief that they have probable cause that you are driving drunk. Probable cause for a Columbus DUI arrest is established based on everything the officer has observed to that point.
Upon arrest for DUI in Columbus, you will be transported to a police station (not necessarily the station of the officer that is making the arrest). It is at the station where the officer will request a breath, blood, or urine test. This testing must be done within a certain time period from your DUI arrest.
Also, at the station, the officer may attempt to interview regarding your intake of alcohol and what you had been doing prior to the stop. The officer must Mirandize you for this interview.
