If, following his arrest, the person arrested refuses upon the request of a law enforcement officer to submit to a chemical test of his breath, after being informed that his refusal will result in the revocation or denial of his privilege to drive, no test shall be given; but the law enforcement officer shall forward to the Department of Motor Vehicles a sworn report that he had reasonable grounds to believe that the arrested person had been driving or was in actual physical control of a motor vehicle upon the public highways of the city while under the influence of intoxicating liquor, and that the person has refused to submit to the test upon the request of the law enforcement officer after being informed that such refusal would result in the revocation or denial of his privilege to drive. (Ord. 299 § 1(c), 1969).
