A. It is unlawful for any person who is an habitual user of narcotic drugs or any person who is under the influence of intoxicating liquor or narcotic drugs or other drugs such as antihistamines, tranquilizers, ephedrine compounds or soporific medications which would impair the driver's ability to drive any vehicle within this City.
B. Upon the trial of any action or proceeding arising out acts alleged to have been committed by any person while driving or in actual physical control of the vehicle while under the influence of intoxicating liquor, evidence of the amount of alcohol in the person's blood at the time of the act alleged as shown by a chemical analysis of his breath, blood, urine, saliva or other bodily substance is admissible, and the result of any such analysis shall give rise to the following presumptions:
1. If there was 0.05% or less by weight of alcohol in the person's blood, it shall be presumed that such person was not under the influence of intoxicating liquor.
2. If there was in excess of 0.05% but less than 0.10% by weight of alcohol in the person's blood, such fact shall not give rise to any presumption that the person was or was not under the influence of intoxicating liquor, but such fact may be considered with other competent evidence in determining whether such person was under the influence of intoxicating liquor.
3. If there was 0.10% or more by weight of alcohol in the person's blood, it shall be presumed that such person was under the influence of intoxicating liquor.
4. The foregoing provisions of this subsection shall not be construed as limiting the introduction of any other competent evidence bearing upon the question whether or not the defendant was under the influence of intoxicating liquor.
C. Every person who is convicted of a violation of this Section shall be fined not less than one hundred dollars ($100.00) nor more than five hundred dollars ($500.00). (Ord. 0-77-17, 6-7-1977)
