Broken Links and 404 Error Pages

The Department of Transportation (DOT) reviews our website periodically for broken or out-of-date links. To report problems with links on our site, please Contact Us.

A 404 error page is returned for several reasons:

  • A internal broken link
  • A mistyped URL or an out of date bookmark/favorite
  • A search engine link that is out of date

DOT will use a simple 404 error statement that the requested URL could not be found on our site, e.g., “Did you mean to type ‘suggestion here’?”
