The change in LTL tonnes per day was attributable to a 17.3 per cent increase in LTL shipments per day that was partially offset by a 5.5 per cent decrease in LTL weight per shipment, said the Nasdaq-listed company statement.
'Revenue and shipment growth for the first two months of the third quarter reflects strength in both the domestic economy and demand for our service,' said Old Dominion CEO Greg Gantt.
'These factors have continued to support our ability to win market share and improve our yields. While our daily volumes increased during August, our growth was affected by the recent rise in Covid cases as well as various other matters impacting customers' supply chains throughout the country, Mr Gantt said.
'As a result, we made the decision to offer a financial vaccination incentive that we believe is an important investment for the safety and well-being of our OD Family of employees,' he said.
Old Dominion Freight Line is one of the largest North American less-than-truckload motor carriers and provides regional, inter-regional and national LTL services through a single integrated, union-free organisation.
