"'Don't Mess With Texas'"

Don’t Mess With Texas’ was the slogan of an advertising campaign created by the Texas Department of Transportation in 1986 as an attempt to reduce roadside litter in the state. It appeared on roadside billboards, radio, television and printed adverts and soon became a cultural icon. Texans have adopted the slogan as a demonstration of state pride and despite being a registered federal trademark it appears on many souvenir items, from beer mats to bumper stickers.
