OLD DOMINION FREIGHT LINE EXCEEDS GUIDANCE WITH FIRST-QUARTER

EARNINGS OF $0.38 PER DILUTED SHARE

58.3% Earnings Growth Driven by 29.5% Increase in Revenue

THOMASVILLE, N.C. (April 22, 2005) – Old Dominion Freight Line, Inc. (NASDAQ: ODFL) today announced record financial results for the first quarter ended March 31, 2005. Revenue from operations increased 29.5% to $236,770,000 for the quarter from $182,769,000 for the first quarter of 2004. Net income rose 63.6% to $9,343,000 from $5,712,000. Earnings per diluted share for the first quarter of 2005 were $0.38, up 58.3% from $0.24 for the first quarter last year. Old Dominion’s operating ratio for the first quarter of 2005 improved to 92.7% from 94.0% for the first quarter of 2004. All prior-period share and per share data in this release have been adjusted to reflect the Company’s three-for-two stock split effective in May 2004.

“We are pleased to report strong profitable growth for the first quarter of 2005, which represents our fourth consecutive quarter of revenue growth above 20%” commented Earl E. Congdon, Chairman and Chief Executive Officer of Old Dominion. Because a majority of this growth was within our existing service center network, we continued to produce increased operating leverage for the quarter. As a result, the first quarter represented our 14^th consecutive quarter of improvement in our operating ratio and growth in net income in excess of 30%, both on a comparable quarter basis.

“Old Dominion’s revenue growth for the quarter reflects a 21.5% increase in LTL tons and a 3.1% increase in LTL revenue per hundredweight, excluding fuel surcharges. We also experienced an 18.2% growth in LTL shipments and a 5.9% increase in LTL revenue per shipment, excluding fuel surcharges. We maintained our pricing discipline during the quarter while increasing our volumes and market share.

“With a service center network covering over 90% of the U.S. population, our primary focus is to leverage our investment in this network through increased freight density by increasing market share. During the first quarter, we benefited from our expansion activities in 2004, which included opening 12 new service centers, expanding our direct service into Oregon and Washington and initiating full-state coverage in Michigan and Wisconsin. During the first quarter of 2005, we also opened a new service

center in Colorado Springs, Colorado, and acquired Wichita Southeast Kansas Transit (“WSKT”) in a transaction we expect will be accretive to our 2005 financial results. Through this acquisition, we expanded our network by 10 service centers to 149 at the end of the quarter, increased our direct coverage to 41 states and increased our full-state coverage to 31 states. During the remainder of 2005, we plan to open four to five additional service centers, including our first service centers in Vermont and Maine.

“Through this expansion, we strengthen our unique competitive position as an efficient, non-union transportation company with the long-haul capabilities of a national carrier and the infrastructure and service capabilities of a regional carrier. The value we present our customers as a comprehensive single-source solution for their transportation needs is evident in our ability to increase revenue, primarily through market share expansion, at a rate consistently and significantly above the industry.”

Based on the Company’s operating and financial results for the first quarter and its assessment of current and near-term business conditions, Old Dominion today affirmed its guidance for 2005 earnings per diluted share in a range of $2.03 to $2.08. In addition, the Company today established its earnings guidance for the second quarter of 2005 in a range of $0.50 to $0.53, compared with $0.43 earned in the second quarter of 2004.

Mr. Congdon concluded, “Our first-quarter results represent a sound start to achieving our earnings guidance for 2005. We are confident that Old Dominion remains well positioned to continue expanding its market share as 2005 progresses.”
