"fatalities that occur in crashes where at least one driver or non-occupant (pedestrian or bicyclist) involved in the crash has a positive Blood Alcohol Concentration (BAC) value."
The only way your scenario (sober driver, drinker passengers) would be counted is if they ran into a drinking pedestrian or bicyclist.

Ooops! just opened the gate to a "WUI" and "BUI" discussion... '-]
Any alcohol found on the scene of an accident is counted.
I know several people (yes, more than one) who have been convicted of DUI for riding their horse while under the influence of alcohol.
Sooo...following that reasoning, if you are sober, but carry a drunk friend home on your back, can that friend be convicted of DUI even though you're sober?
