DOT Website Linking Policy

Evaluation Criteria

Prior to posting a link, the Department of Transportation (DOT) evaluates the link to determine if it meets one of the following criteria:

  • The link is to an official U.S. Federal government Web site.
  • The link is to a Web site that provides official U.S. government information or services.
  • The link is to a Web site with content that complements existing information, products, and services on the DOT site where it is posted.

In addition, all links on DOT Web sites must meet all of the following criteria:

  • The Web site being linked has content that is relevant, useful, and authoritative for citizens, businesses, and/or government officials.
  • The Web site being linked has information that appears to be accurate and current.
  • The Web site being linked has a posted privacy policy that clearly describes the organization’s information handling practices.
  • The Web site being linked is "user-friendly”.

Links to Government Web sites

DOT may post links to any government Web site that is publicly available unless directed not to by the agency that owns the site. Federal government-owned or sponsored Web sites will generally have .gov, .mil or domains, however, some may occasionally end in .com, .org or .net. DOT may also link to Web sites created by public or private sector partnerships with the federal government, and state and local government Web sites.

Links to Non-Government Web sites

In rare instances, DOT Web sites will contain links to non-government owned or sponsored Web sites, provided these sites provide government information and/or services in a way that is not available on an official government Web site. DOT Web sites provide these links as a public service to allow Web visitors to obtain information or services related to the site they are visiting.

The U.S. government, including the Department of Transportation, neither endorses nor guarantees in any way the external organizations, services, advice, or products included in these Web site links. Furthermore, the U.S. government neither controls nor guarantees the accuracy, relevance, timeliness, or completeness of the information contained in non-government Web site links. (See Disclaimer of Endorsement more information on this topic.)


DOT Web sites will not link to any Web site that exhibits hate, bias, or discrimination. Furthermore, DOT reserves the right to deny or remove any link that contains misleading information or unsubstantiated claims, or is determined to be in conflict with DOT’s mission or policies.
