It is recognised that the 85% "rule" is there as a safety factor as advocated by the ccc & cc and is taken into concideration when accidents occur eg;loss of control of an outfit.It is applied just like when a solo accident occurs and factors such as weather,speed and traffic are taken into concideration,which also are not writen into the policy.Since most people,especially the "newbies" would not think to enquire about the 85% "rule" and how much this factor is taken into concideration when taking out insurance, it seems a folly to advocate to anyone to tow at near maximum limits before checking this issue.
