Exhibit 99.1 Press Release dated September 20, 2006

Waco, TX (PR Newswire) - September 20, 2006 - Central Freight Lines, Inc. (Nasdaq/NMS: CENF) announced today that it has entered into a First Amendment to its previously announced Agreement and Plan of Merger (as amended, the "Merger Agreement") with North American Truck Lines, LLC ("NATL") and Green Acquisition Company ("Green"). The Merger Agreement provides that Jerry Moyes and certain related parties would become the owners of Central, and Central would cease to be a publicly traded company.

	·	Waives the purchaser's need to obtain financing as a condition to closing the merger; and

	·	Clarifies that there is no pending litigation against Central that must be settled prior to closing the merger, other than the class action and derivate litigation for which agreements in principle to settle have been reached, as described in more detail below.

Other principal terms of the Merger Agreement, including price, remain unaltered by the First Amendment. As a result, pursuant to the Merger Agreement, at the effective time of the merger, all Central stockholders, other than Mr. Moyes, certain related parties, and a trust created for the benefit of Mr. Moyes' children, would receive cash in an amount equal to $2.25 per share of Central common stock.

As previously announced, Central also has reached oral agreements in principle with the plaintiffs to settle pending securities class action litigation, two purported derivative actions related to the period between the date of Central's initial public offering and August 2004, and a third derivative action related to the merger transaction. These agreements in principle, if completed, would satisfy a condition to closing of the merger. The agreements are subject to the completion of the usual and customary documentation for such settlements, and are subject to, and conditioned upon, final court approval. The settlements are expected to be funded from the proceeds of Central's directors' and officers' liability insurance policy.

Central also announced today that it had recently responded to a second set of comments from the Securities and Exchange Commission (the "SEC") with respect to its proxy statement for the 2006 Annual Meeting of Stockholders (the "Annual Meeting"). Approval of the Merger Agreement will be presented for a vote of Central's stockholders at the Annual Meeting. Subject to completion of the SEC review process, Central has identified November 13, 2006, as the tentative date for the Annual Meeting.

Once the SEC's review of the proxy statement is finalized, the definitive proxy statement will be mailed to Central's stockholders to solicit proxies for voting on the merger and other matters presented at the Annual Meeting.

Bob Fasso, Central's Chief Executive Officer and President, stated: “We are very pleased with these developments. We believe they represent significant steps toward completion of the merger. In particular, we believe that the elimination of the financing condition and the achievement of agreements in principle to settle litigation were important advancements toward completing the merger.”

Stockholders are urged to read the definitive proxy statement carefully when it becomes available because it will contain important information about Central, the merger transaction, and related matters. Stockholders will be able to obtain free copies of the proxy statement and other documents filed with the SEC by Central through the SEC's web site at www.sec.gov. In addition, stockholders will be able to obtain free copies of the definitive proxy statement from Central.
