(1) before the trip begins; or
(2) after the goods reach the destination if, after the carrier uses due diligence to notify the consignee, the consignee fails to take possession of the goods.
(b) A common carrier is liable as a common carrier from the beginning of the trip until the goods are delivered to the consignee at the point of destination.
(c) For purposes of this section, a trip begins when the bill of lading is signed.
