I suspect these are relatively slight compared to effect of longitudinal loads and would be considered part of the factor of safety rather than explicitly included.

Thank for your help. I was able to get one planned measuring event where I could control just which axle was over the reference location. We must change cooper E80 to only one load or just push it on the line?
