"The Texas Department of Transportation is phasing out the widespread use of ceramic buttons, known affectionately by motorists as "turtles," on state roadways. Beginning in October, contractors on new state roads will no longer be allowed to use the 3/4-inch-high buttons as lane dividers. Gone will be the familiar thud-thud-thud sound of tires running over buttons that has alerted Texas drivers to lane changes for more than 40 years. The buttons will be allowed only on the shoulders of rural state highways."
