Besides being one of the state's most popular slogans, Don't mess with Texas® also is proving to be effective as an anti-littering message. Established by the Texas Department of Transportation in 1986, Don't mess with Texas® has helped reduce visible litter by 34 percent on TxDOT-maintained roadways between 2009 and 2013, according to TxDOT's 2013 Texas Litter Survey.
