349.07(7)(a)(a) The department may, when it deems necessary for the public safety, by order provide for the installation of yield signs on state trunk highways and connecting highways, and the governing body of any city, or county, may by ordinance or resolution provide, when it deems it necessary for the public safety, for the installation of yield signs on any through highway which has been so declared under sub. (3) and under its exclusive jurisdiction to regulate merging traffic movements and conflicting movements occurring within the intersection of 2 or more highways. Yield signs shall not be used in lieu of stop signs where a highway directly crosses a through 2-way highway.

349.07(7)(b)(b) The governing body of any town, city, village or county may by ordinance or resolution provide for the installation of yield signs at any intersection over which it has exclusive jurisdiction, but if the intersection is part of a through highway such yield signs can be installed at such intersections only as provided in par. (a).

349.07(8)(8) The governing body of any town, city, village or county may by ordinance or resolution provide for the installation of stop signs and traffic signals at intersections on highways over which it has exclusive jurisdiction.

349.07 AnnotationLegislative Council Note, 1977: Section 349.08 (6) (a), relating to the placement of yield signs, is renumbered s. 349.07 (7) (a) and amended to prohibit the use of yield signs in lieu of stop signs where a highway directly crosses a through 2-way highway; the present prohibition against the use of yield signs in lieu of stop signs is overly broad in that it is not restricted to highways which directly cross through highways. By definition, the entrances to a “through highway” from intersecting highways must be controlled by traffic control signals or stop signs; “through highway” is defined in s. 340.01 (67). [Bill 465-A]

349.085349.085 Authority to install stop signs at railroad grade crossings. Local authorities may, by ordinance, when they deem it necessary for the public safety, install official stop signs at public traveled railroad grade crossings on highways maintained by the respective authorities.

349.09349.09 Authority to remove prohibited signs or signals.

If such nuisance is not removed within 30 days after such notice is given or if an unauthorized signal or device is found to be in operation at any time after such notice is given, the authority in charge of maintenance of the highway may cause the nuisance to be removed and collect the expense of removal from the person notified to remove it. The expense of removal may be charged against the premises and, upon certificate of the highway authority causing the removal, assessed as are other special taxes.

349.10(1)(b)(b) Designate by pavement marking certain places on highways as safety zones or erect and maintain islands of safety and regulate and control traffic with respect to such safety zones and islands of safety.

349.10(1)(f)(f) By order, ordinance or resolution and by the erection of appropriate signs, prohibit U-turns at specified locations. The local authority with the approval of the department may prohibit U-turns and erect appropriate signs on state trunk highways within cities, villages and towns.

349.10(2)(2) No local authority shall declare any part of a connecting highway between portions of the state trunk highway system to be a one-way highway or prohibit right or left turns or U-turns at any intersection of one such connecting highway with another without due regard for the expeditious flow of intercity traffic using the state trunk highways and without first conferring with the department on the problems involved.

349.105349.105 Authority to prohibit certain traffic on expressways and freeways. The authority in charge of maintenance of an expressway or freeway may, by order, ordinance or resolution, prohibit the use of such expressway or freeway by pedestrians, persons riding bicycles or other nonmotorized traffic or by persons operating mopeds or motor bicycles. The state or local authority adopting any such prohibitory regulation shall erect and maintain official signs giving notice thereof on the expressway or freeway to which such prohibition applies.

349.11(1)(a)(a) Whenever the department with respect to the state trunk highway system and the local authorities with respect to highways under their jurisdiction determine upon the basis of an engineering and traffic investigation that any statutory speed limit is greater or less than is reasonable or safe under the conditions found to exist upon any part of a highway or that the actual speed of vehicles upon any part of a highway is greater or less than is reasonable and prudent, the department with respect to the state trunk highway system and the local authorities with respect to highways under their jurisdiction may, subject to the limitations set forth in subs. (2) and (3), determine and declare a reasonable and safe speed limit on the highway or part thereof in question. When appropriate signs giving notice of such speed limit have been erected and are in place, such speed limit shall be effective at all times or at such times as indicated by the signs.

(2) and (3), determine and declare a reasonable and safe minimum speed limit on the highway or part thereof in question. When appropriate signs giving notice of such minimum speed limit have been erected and are in place such minimum speed limit shall be effective at all times or at such times as indicated by the signs.
