The City will submit to the State Highways and Transportation Commission for approval any ordinances, rules, regulations, or resolutions appertaining to the regulation of speed where such ordinances, rules, and regulations are applicable to Section 305.010 of this Title and will not enact or keep in force any ordinance not approved by the Commission.

Upon the trial of any violation of ordinances regulating the speed of motor vehicles upon the streets of the City, the Chief of Police, and any and all other Officers of the Police Department of the City are hereby authorized to use radar, speed guns or any other approved electronic devices for measuring speed to determine the violations of ordinances regulating speed upon the streets of the City. Radar, speed guns or any other electronic devices for measuring speed of motor vehicles shall be admissible in evidence. Such evidence shall be construed as follows:
1. 
If the radar, speed gun or other electronic device for measuring speed when used in any specific incident shows that the speed at the time was less than maximum speed allowed by ordinance on any street in the City, it shall be presumed that the person was not exceeding the speed limit.
2. 
If the radar, speed gun or other electronic device for measuring speed when used in any specific incident shall register a speed of the driver of the motor vehicle that is in excess of the maximum speed set by ordinance for the particular street on which the driver was operating, this fact shall be prima facie evidence that the person was violating the City ordinance.

The foregoing provisions of this Chapter shall not be construed as limiting the introduction of any other competent evidence bearing upon the question whether the person was violating the City ordinance regulating the maximum speeds in the City.
