Safety Seals for Delivery Trucks

Our small co pack facility is working toward initial SQF certification.  Most of our incoming and outbound shipments are LTL and most LTL drivers will not put a new seal on the truck after each stop.  Looking for advice on how to address this for SQF.  Thanks in advance for your input.

Then you can simply state "driver lock" in the column where it says "Seal #". 

LTL is always a problem in the world of SQF.  Drivers get lazy and don't want to lock the trailers every stop, so you'll reject a lot of loads if you've written a hard requirement for LTL's to be locked in your SOP.  We rely on the pallets being inspected and seeing that the pallets/case seals are intact as evidence the material is still secure.
