I wanted to make sure you got my last response, since it appears you did not read the answer. I apologize for the confusion. This was my post:
That's odd, since it comes straight from the Virginia statute site. Sorry about that. I just tried to send to another link from Virginia statutes and it keeps copying as a dangerous link, so I have copied the statute below when it was changed in 1994.
§ 18.2-266. Driving motor vehicle, engine, etc., while intoxicated, etc.
It shall be unlawful for any person to drive or operate any motor vehicle, engine or train (i) while such person has a blood alcohol concentration of 0.100.08 percent or more by weight by volume or 0.08 grams or more per 210 liters of breath as indicated by a chemical test administered as provided in this article, (ii) while such person is under the influence of alcohol, (iii) while such person is under the influence of any narcotic drug or any other self-administered intoxicant or drug of whatsoever nature, or any combination of such drugs, to a degree which impairs his ability to drive or operate any motor vehicle, engine or train safely, or (iv) while such person is under the combined influence of alcohol and any drug or drugs to a degree which impairs his ability to drive or operate any motor vehicle, engine or train safely.
For the purposes of this section, the term "motor vehicle" shall includeincludes mopeds, while operated on the public highways of this Commonwealth.
