Columbus DUI Detection Phase One: Drunk Driving

Over the next few days I will try to give you some useful information regarding DUI testing procedure in Columbus; well in the State of Ohio actually. I hope this information isn't terribly boring and will be useful whether you are currently facing a DUI charge, or you're the type of person that just likes to be informed.

Police are looking for specific clues to give them probable cause to arrest a person for OVI or DUI. Unfortunately, most people being detained and investigated for DUI have no idea what the officer is looking for. Columbus Police are trained to detect DUI using the National Highway Traffic Safety Administration's testing procedures (NHTSA manual). 

Big shocker: the first clues are those observed while you're driving. . . usually. If you're so intoxicated that you don't realize you're driving the wrong way down a one way street or you've been in an accident, well, that's going to be a problem. Other clues are much harder to detect. Here is a list of possible DUI indicators taken directly from the NHTSA manual:



Last week the Arizona Supreme Court ruled that state cannot prosecute a driver for marijuana DUI unless that driver shows indications that they are impaired by the drug at the time of the stop. This is a major victory in the battle to protect people's constitutional rights. 
The Court found that a certain chemical compound can be found in a person's blood or urine when they are under the influence of marijuana. Further, they found that  chemical compound is not present when a person regularly uses marijuana but is not under the influence at the time of arrest.
