What was it at 7:30 when the crash happened? The article says it was .02 at 9:00. That is an hour and a half after the accident.
You don’t go from sober to drunk in 1hr 30 minutes. I’m not sure by law if you can extrapolate (?) BAC back. I would think that if you do a BAC test you have to go with what you got. But whatever. I defer to jagusafr.
Whoops, sorry. You most assuredly can go from sober to drunk in 1hr 30 minutes. I meant to say “drunk to sober”.
