(1998 Code, sec. 70.01)
The director of traffic control shall determine on the basis of engineering and traffic surveys the reasonable and safe maximum speed limits for each street within the town and submit recommendations based upon his investigation to the town council. On the basis of the recommendations of the director of traffic control, the town council may alter the maximum speed limit established by this code as the council deems necessary. The director of traffic control shall post the maximum and minimum speeds established by this code by appropriate signs in conspicuous places so that every motorist may be aware of the speed limits. The director of public works shall serve as the director of traffic control in the absence of other specific appointment.
(1998 Code, sec. 70.02)
Ordinances establishing speed limits for specific streets or portions of streets have not been included in this code, but all such ordinances are on file in the town secretary’s office and are specifically saved from repeal upon adoption of the Code of Ordinances. A person commits an offense if he operates or drives a vehicle on the designated streets at a speed greater than the speed designated by the schedule on file in the town secretary’s office for that street or portion of that street, and any speed in excess of the limit provided in the schedule shall be prima facie evidence that the speed is not reasonable nor prudent and is unlawful.
