The act defines school zones as all roadways within at least 1,000 feet of a school property boundary, except state highways unless they are designated as part of a school zone with the written approval of the Colorado department of transportation, and including school zones established before August 12, 2026, that are 200 feet or more from a school property boundary. A school zone must have appropriate signs posted indicating it is a school zone and that the penalties and surcharges within the school zone will be doubled.
     The act allows a local government that has jurisdiction over a school zone to reduce the size of a school zone after first holding a public hearing, but the act does not allow a school zone to be reduced to less than 200 feet from a school property boundary. Additionally, the act does not prohibit local governments from expanding school zones to beyond 1,000 feet from a school property boundary.
     The act limits requirements the state, a county, a city and county, or a municipality must complete regarding placing and using an automated vehicle identification system along a safe route to school.
     The act allows a local government to designate a portion of a roadway immediately adjacent to a school property boundary as a school street and requires the local government to post signs indicating it is a school street if the local government has jurisdiction to do so. The local government may close a school street to traffic. If there is traffic on the school street, the maximum speed limit is 10 miles per hour and vehicles must yield the right-of-way to pedestrians, bicyclists, or micromobility users. The local government may suspend additional traffic provisions on the school street that endanger pedestrians, bicyclists, or micromobility users.
