1. Farm trucks or machinery hauling corn, soybeans, wheat, bulk milk, livestock, tobacco, manure, turf, sod, and silage are allowed a 7.5 percent variance from axle, tire and gross vehicle weight limits with certain restrictions. The variance is an increase above the set weight limit and allows for load weights that may change due to shifting or from picking up moisture.
2. You must always comply with all three weight limits. If you are under the gross vehicle weight limit you must still comply with the tire and axle weight limits. If you could ignore the axle and tire limits by meeting the gross vehicle weight limit, it would become legal to have very heavy weights on a single axle, which could be dangerous and cause many roads or bridges to be put on restricted weight status.
3. The variance applies from the place of production to the first place of delivery, or the place where title is transferred, whichever is first.
4. For trucks hauling corn, soybeans, wheat, livestock, milk and tobacco these variances don’t apply during February or March.
5. These variances also don’t apply when there is a restricted weight on a road, like a bridge or road with a reduced weight, including those with a reduced weight due to frost/thaw.
6. If you exceed the variance, you are penalized as if there was no variance.
