Don't mess with Texas® - Official 

Since 1986, Don’t mess with Texas® has been saying one thing – don’t litter. And from the launch of the iconic ad with Stevie Ray Vaughan, Texans have answered the call, pitched in, and made this campaign one of the most successful anti-littering efforts in history. Watch all 40 years of commercials here! 

The Don’t mess with Texas slogan is a trademark held by the Texas Department of Transportation.
