We had another DRed HV a few days ago. Driver gets a last minute add/cut but the HV paperwork didn't get pulled from the original drivers log. Next day they see it was DRed and send the driver back to try to get a signature. We've been told that if we DR a HV even if we don't know it was a HV we will be responsible for the cost if cosignee claims non-recipt. My question is why do we still get HV that are releasable? Can't they make any package valued at over $1k default to signature required, or even adult sig req?
