System, methods, and computer program products are provided for enhanced freight tracking and monitoring. The system may track the location of a freight shipment within a carrier's transportation network from the time it is picked up by a carrier from a consignor until it is delivered to a consignee, provide for weight determinations and shipping re-classifications of the freight shipment during transport, and provide real-time status information and reports to the carrier, consignor, and/or consignee.
