Ohio may need a new acronym for impaired driving. Our state has used various drunk driving abbreviations in the past. There was ‘DUI’ for Driving Under the Influence and then ‘OMVI’ for Operating a Motor Vehicle Intoxicated. Now that Ohio law does not require the vehicle to be motorized, we use ‘OVI’ for Operating a Vehicle under the Influence. In the future, the acronym may be ‘OVD’ for Operating a Vehicle Dehydrated. A study published in Physiology & Behavior suggests dehydrated driving is similar to intoxicated driving.
