Shippers Seen at Inspections
Shipper names recorded by roadside inspectors over roughly the last three years. Only inspected loads appear, so this is a sample of who the carrier hauls for, not a complete customer list. Names are as entered at the roadside; blanks and placeholders such as “N/A” or “same as carrier” are left out.
