At the 2 hr mark after they started loading I would be calling whomever arranged the load with us and advise them that their 2 hrs of free time are about to expire and that waiting time will begin now. That allows them to call the shipper and verify the time. Once loaded and we know the amount of waiting time we would be asking for a revised confirmation showing the proper amount. The key is making sure that the driver has the shipper clearly sign for the time started and time completed. If the shipper refuses, then make a note of it. Like anything proper documentation will fix a lot of issues down the road.whatiship - If you were the carrier, how would you get the waiting time out of them?
