Oxazepam, then wine 24 hours later. Can this be a factor in impaired driving?

15 mg of oxazepam taken at 11 pm & 2 glasses wine are consumed 24 hours later can this be a factor in impaired driving

I took 15 mg of oxazepam at 11:00 p.m. The next nite I had 2 glasses of wine  8:00 p.m. & 10:00 w/ dinner. I was pulled over for speeding & arrested. My BAC was 0.02.  They did a blood test. The oxazepam read which I took 23 hours prior was <100 ng/mL.  The toxicologist said that even thou my BACs were low & drug read was low I was driving impaired. There was a 23 hour time span between the 2. Is she right?

Considering that half-life of oxazepam is reported to be 4–15 hours, some oxazepam was possibly still in you system -- the question is how much. If the level was close to 100 ng/ml, it is conceivable that combined with alcohol, it could have caused some degree of impairment in some people (i.e. those with more susceptible nervous system). It is hard to be more specific w/o the exact oxazepam level in your bloodstream at that time.
