The safety-service director is authorized and directed to supply police officers with citation tags for the purpose of giving notice to persons in violation of any provision of the traffic code or of other laws or ordinances affecting the use of highways. The notice may be given by delivering the tag to the violator, or by affixing it to the vehicle by means of which the violation occurred. Citation tag shall direct the violator to appear and to present the tag at a designated office in the city hall at or before a date and hour specified thereon. Nothing in this section shall be construed to abridge the power of a police officer to arrest any violator and take him into custody.
