Sign Sizes

Volunteer Signs

Volunteer recognition signs are two-panel, single-post signs provided by ADOT. The ADOT logo is 24x12 inches and sits in a separate panel above the recognition panel. The recognition panel is 24x24 inches and sits in a separate panel under the ADOT logo panel.

There are two sign options for ADOT recognition panels for volunteers. Consider how you would like to present your group's name (e.g., how many characters are in your name) while choosing the option that's best for you.

  • Option 1: Three lines with nine, three-inch characters for each line
  • Option 2: Four lines with 10, two-and-half-inch characters for each line

Sponsor Signs

Sponsor recognition signs are a way for civic-minded sponsors to adopt a segment or segments of Arizona's highways for litter cleanup. Sponsors can do so by hiring maintenance providers from a list provided by ADOT. Sponsor signs are not provided by ADOT and must be purchased from approved maintenance providers. Sponsor signs are single-panel, two-post signs that are 72x48 inches. The sponsor plaque area is 48x24 inches.

For a list of maintenance providers and for more information, visit the Sponsor Program page.
