In Ohio, driving under the influence includes driving while intoxicated with too much alcohol, or driving under the influence of a drug of abuse. One can be convicted be "under the influence" if a jury determines that:
"the defendant consumed some alcohol or drug of abuse, whether mild or potent, in such a quantity, whether small or great, that it adversely affected and appreciably impaired the defendant's actions, reactions, or mental processes under the circumstances then existing and deprived him of that clearness of intellect and control of himself which he would otherwise have possessed."
In Ohio, even if you are not "under the influence," you may still be guilty of a alcohol related crime if you are "over the legal limit." Driving over the legal limit is not the same as driving under the influence" (although the two may certainly occur at the same time and one may be charged and convicted of both). In Ohio, the legal limit for persons 21 and over is any of the following:
.10% (by weight) for blood, or
over .10 of 1 gram (by weight) per 200 liters of for breath, or
.14 of a gram (by weight) per 100 milliliters of urine.
For persons under 21 it is even less (e.g. .02% (by weight) for blood.)
You state that your blood alcohol was .098, 2 1/1000's less than the legal limit. Certainly enough to convict on "under the influence".
The only stupid one here is the person that believes their not drunk when they have drank to much!
