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 eight one-hundredths 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.
