I'm not a Virginia lawyer, but my research suggests that a 10-day jail sentence in your state, for DUI, is for a first offense with a blood alcohol reading of .21 or higher, and it's mandatory;  a second offense would be a month.  "Mandatory" means the judge doesn't have a choice.It looks like the only way you stay out of jail is to be found not guilty, which might be very difficult with that high a reading;  it's possible that if your reading was exactly .21 or .22, a good lawyer might be able to get you sentenced for only being over .15, which is 5 days in jail, again mandatory.  One place to look for a qualified DUI attorney in your area is our website, http://attorneypages.com
