Sounds like to me, while making the turn the OP got one front wheel off the pavement in a 3 inch deep ditch. And had the other front wheel on top of a 6 inch speed bump. So a 9 inch slant in total. So the question would be, is it operator error, or is the road design so bad, that the op had no choice in making that turn, that way.
I sure don't know. But I suspect the turn may have been made to wide or sharp, BY the OP. And hence the issue. Kind of like blamming the CG if you hit one of their trees. Make sense only if you have to blame everything on somebody else
