Is It Illegal To Change Lanes In An Intersection In Wisconsin?

  • Time to read: 5 min.

It is usually legal to change lanes while passing another vehicle in an intersection in Wisconsin, as long as there are two lanes of approved, same-direction traffic. However, there are some exceptions to this.  

Also, changing lanes on the approach to an intersection is problematic too. If within 100 feet of the intersection without two lanes available, changing lanes is illegal.

These are highly unusual, specific laws relating to changing lanes at or near an intersection. Few states stipulate as such. Read on to learn about these and other relevant Wisconsin laws.

Where Are The Laws That I Can Look To In Order To Confirm Whether Lane Changes In An Intersection In This State Are Legal/Illegal?

Passing another vehicle both traveling in an identical direction when within 100 feet of an intersection – or traveling across it – is not permitted unless two lanes of same-direction traffic are validated under statute 346.10.

There is also an exception to this rule made in sub 3:

(2) Subject to the exception stated in sub. (3), the operator of a vehicle shall not overtake and pass any other vehicle proceeding in the same direction when approaching within 100 feet of or traversing any intersection unless the roadway is marked or posted for 2 or more lines of vehicles moving simultaneously in the direction in which such vehicle is proceeding or unless permitted or directed by a traffic officer to pass at such intersection.

(3) Outside of a business or residence district, the restrictions which sub. (2) places upon passing at an intersection apply only if such intersection is designated in the direction of travel by a traffic control signal, stop sign, yield sign or sign that warns traffic of existing or potentially hazardous conditions on or adjacent to the roadway.

Rights-of-way for intersections are specifically laid out in statute 346.18:

(1)  General rule at intersections. Except as otherwise expressly provided in this section or in s. 346.19, 346.20, 346.215, or 346.46 (1), when 2 vehicles approach or enter an intersection at approximately the same time, the operator of the vehicle on the left shall yield the right-of-way to the vehicle on the right. The operator of any vehicle driving at an unlawful speed forfeits any right-of-way which he or she would otherwise have under this subsection.

(2) Turning left or making a U-turn at intersection. The operator of a vehicle within an intersection intending to turn to the left or make a U-turn shall yield the right-of-way to any vehicle approaching from the opposite direction.

(3) Rule at intersection with through highway. The operator of a vehicle shall stop as required by s. 346.46 (2) (a), (b) or (c) before entering a through highway, and shall yield the right-of-way to other vehicles which have entered or are approaching the intersection upon the through highway.

Getting into the correct position to turn and turning appropriately is legislated under statute 346.31:

(1)  Turns indicated by pavement markings. Where state or local authorities have placed pavement markings or signs within or adjacent to an intersection directing traffic turning at such intersection to follow a particular course, the operator of a vehicle turning at such intersection shall comply with such directions. In the absence of such pavement markings or signs, the operator of a vehicle intending to turn at an intersection shall do as provided in subs. (2) to (4).

(2) Right turns. Both the approach for a right turn and the right turn shall be made as closely as practicable to the right-hand edge or curb of the roadway. If, because of the size of the vehicle or the nature of the intersecting roadway, the turn cannot be made from the traffic lane next to the right-hand edge of the roadway, the turn shall be made with due regard for all other traffic.

The statute further clarifies left-turns, U-turns, and other activities too.

Also, there are limitations set out under statute 346.09 for overtaking on the left side:

(1)  Upon any roadway where traffic is permitted to move in both directions simultaneously, the operator of a vehicle shall not drive to the left side of the center of the roadway in overtaking and passing another vehicle proceeding in the same direction unless such left side is clearly visible and is free of oncoming traffic for a sufficient distance ahead to permit such overtaking and passing to be done in safety. In no case when overtaking and passing on a roadway divided into 4 or more clearly indicated lanes shall the operator of a vehicle drive to the left of the pavement marking indicating allocation of lanes to vehicles moving in the opposite direction or, in the absence of such pavement marking, to the left of the center of the roadway. Except as provided in sub. (3) (b) and s. 346.05 (1) (g), in no case shall the operator of a vehicle drive in a lane when signs or signals indicate that such lane is allocated exclusively to vehicles moving in the opposite direction.
