On the crest of the USS Texas, beneath the symbols of a Virginia-class submarine, four words ride along with the boat: “Don’t Mess with Texas!” A line many people hear as pure state bravado began as something smaller, dirtier, and closer to the pavement: a message for drivers tossing trash out of car windows.[1]
“Don’t Mess with Texas” is the Texas Department of Transportation’s anti-littering slogan, launched to cut roadside trash. The campaign is credited with reducing litter on Texas highways by roughly 72 percent between 1987 and 1990.[1]
In 1985, the Texas Department of Transportation asked Mike Blair and Tim McClure of the advertising firm GSD&M to create an anti-littering campaign.[1] The audience was unusually specific: 18- to 35-year-old men, the group statistically shown to be most likely to litter.[1]
That detail explains the tone. A polite reminder about civic responsibility was not the obvious way to reach the people the state most wanted to stop. “Don’t Mess with Texas” sounded less like a government notice than a warning from the place itself. It turned a roadside cleanup plea into a matter of Texas pride.
The words went onto major highway signs. They also went into television, radio, and print advertisements.[1] Then they escaped the campaign that created them. The line appeared on tourist souvenirs, entered popular speech, and became what one account describes as “an identity statement, a declaration of Texas swagger” and Texas pride.[1]
A slogan with two lives
Many people came to know the slogan before they knew its official meaning. Outside Texas, and sometimes even inside it, “Don’t Mess with Texas” could sound like a regional threat, a motto, or a piece of cultural chest-thumping. The intended message was plainer: do not litter.[2]
Since 1986, the Texas Department of Transportation has used the phrase to teach that “Don’t mess with Texas” means “don’t litter.”[2] The campaign has continued through commercials, partnerships, cleanup efforts, and education programs aimed at keeping trash off roadsides.[2]
There is still a public ritual attached to the slogan. Each April, the Don’t mess with Texas Trash-Off brings volunteers together across the state to pick up litter, clean roadways, and beautify communities.[3] In 2025, the Trash-Off was hosted in Tyler, Texas, the city identified by the campaign as the place where the Adopt-a-Highway program began 40 years earlier.[3]
The line that got away
Success created a different problem. “Don’t Mess with Texas” became so popular that it was printed, borrowed, repeated, and repurposed far beyond roadside cleanup. The phrase is a federally registered trademark owned by the Texas Department of Transportation, which has tried at times to enforce its rights with cease and desist letters, though with limited success.[1]
The advertising world noticed, too. “Don’t Mess with Texas” received a plaque on the Madison Avenue Walk of Fame and was placed in the Advertising Hall of Fame, an honor given to only two slogans each year.[1] In 2011, a public vote for the best ad from the campaign’s first 25 years picked a commercial featuring the Commemorative Air Force’s Boeing B-17 “Sentimental Journey” pursuing a truck after trash was thrown from it.[1]
For a litter message, that is a strange itinerary: highway shoulder, souvenir rack, advertising hall, submarine crest. The slogan’s famous posture is defiance, but its first enemy was ordinary and small: a hand at a car window, letting go of a can, and a sign ahead saying Texas had seen enough.
