Driving Drunk and Over the Limit, Under Arrest! This seems to be the motto in the Cincinnati area. At least, this is the motto on the electronic billboards on the highways.
So, if I understand it, you can drive drunk as long as you are not over the limit. Likewise, you can be over the limit if you are not drunk! But, don’t drive drunk AND be over the limit. If you do, you will be under arrest.
At least they give you options.
