There are a number of additional laws that apply when operating an Implement of Husbandry (IoH) or an Agricultural Commercial Motor Vehicle (Ag CMV) on the highway. Everyone using Wisconsin roads has the responsibility to know the laws that apply for the vehicle they are driving or operating. Here are a few laws more specific to agricultural vehicles.
s. 346. 05(g) Wis. Stats – Wide IoH with required lighting and marking requirements may:
- Extend over the center of road into the lane intended for travel in opposite direction.
- Extend into passing lane on a 3-lane highway.
- Extend into another lane intended for travel in the same direction, if it does not impede other vehicles from the rear.
However, operators :
- Must yield the right-of -way to an oncoming vehicle and yield half the roadway.[ s. 346.06 Wis. Stats.]
- May not drive on the left side of the roadway on a grade or curve or area designated as no passing zone if it creates a hazard to oncoming traffic. [s. 346.09(02) Wis. Stats.]
- May not drive so slowly as to impede the normal movement of traffic.
- Must, if practicable, yield the roadway to an overtaking vehicle.
s. 346.09 (3)(b) Wis. Stats – The operator of a vehicle may drive on the left side of the center of a roadway on any portion thereof which has been designated a no-passing zone, as described in par.
