Transport Carrier Network provides access to a national network of pre-qualified transport carriers who advertise parked and en route trailer and truck space for hire at one or more ShipperNet Freight Centers, helping shippers locate available equipment space quickly. With searches up to 500 miles, Transport Carriers are free to work with multiple shippers and warehouses to stop, drop, pool, aggregate or co-load freight en-route to a destination. The online current location system allows transport carriers to provide direct contact information for shippers, enhancing delivery services and reducing costs by optimizing trailer and truck space utilization.
