Section 11-1207. Evidence admitted in court

Upon  the  trial  of  any  action or proceeding arising out of conduct
  alleged to have been committed by any person arrested for a violation of
  any subdivision of section 11-1203 of this title, the court shall  admit
  evidence  of  the amount of alcohol or drugs in the defendant's blood as
  shown by a test administered  pursuant  to  the  provisions  of  section
  11-1205  of  this  title. Evidence that there was five-hundredths of one
  per centum or less by weight of alcohol in such person's blood is  prima
  facie  evidence  that  the  ability  of such person to engage in hunting
  without creating unreasonable risk of injury  or  death  to  himself  or
  other  human  life  was  not  impaired  by  the  consumption of alcohol.
  Evidence that there was less than one-tenth of one per centum by  weight
  of alcohol in such person's blood is prima facie evidence only that such
  person  was  not  in  an intoxicated condition due to the consumption of
  alcohol.
