How are speed limits posted and enforced?
By city ordinance, the speed limit in subdivisions is 25 miles per hour, unless otherwise posted. Other streets and thoroughfares have varying posted speed limits. When there is a change in a particular street’s speed limit, unless it is a flagrant and dangerous violation, there will be a 30 day warning period on traffic violation citations in that particular speed zone. The Madison Police Department does employ the use of speed detection units (radar). Radar is utilized 24 hours a day – 7 days a week on all city streets and highways. The main purpose for the use of radar is to reduce the number of traffic crashes and subsequent injuries and fatalities.
