It is a Class 2 misdemeanor to exceed any of the speed limitations contained in §§ 32-25-12 to 32-25-15, inclusive. However, local authorities, in their respective jurisdictions, may increase the speed limits on through highways if vehicles are, by ordinance of such local authorities, required to stop before entering or crossing such through highways.
