32-25-19.1. Limited speed zones--Signs posted--Violation as misdemeanor.

Notwithstanding § 32-25-7 or chapter 1-26, if the secretary of public safety and the secretary of transportation, after consultation with the director of the highway patrol, agree the limited speed zones are necessary for the protection of life and property, the secretary of transportation may establish limited speed zones as follows:

(1)    Through highway work areas on the state trunk highways; and

(2)    On any segment of the interstate highway system based upon monitored traffic, weather, or road surface conditions.

Temporary reduced speed limits may be established for different times of day, different types of vehicles, varying weather conditions, and any other factor that has a bearing on a safe speed. A limited speed zone is effective when it is conspicuously posted on appropriate fixed or variable signs. The beginning and end of each limited speed zone established under this section shall be conspicuously posted with signs showing the maximum speed permissible. The location and duration of this posting shall be filed with the secretary of transportation. A violation of the speed limit established under the provisions of this section is a Class 2 misdemeanor. Any fine for a violation of this section while workers are present shall be double the usual fine for speeding, but may not exceed the maximum fine for a Class 2 misdemeanor as provided in § 22-6-2. Signs showing that a fine will be double the usual speeding fine shall be erected in advance of the regulatory speed limit signs.
