I guess, in retrospect, it doesn't make much difference what the load is. It seems clear that if you have encountered an accident with any unsecured load, you may have a rock hardened opinion about whether or not it is safe and not important. I know if I had lost a car or wife in an accident with unsecured load (could be hay, tractor, zturn, anything), I would attest to the fact that it is important and should never happen. No one could convince me that it was rare and did not matter if the load was secure or not. On the other hand, if we have never been involved or dodged unsecured loads coming off trailers, it might not seem too important or might feel it is rare. But then, this seems to be how issues are resolved - AFTER enough accidents. I don't know - just wondering - do they scale trucks hauling hay? Best Wishes
