Pavement markings provide guidance for motorists, bicyclists, and pedestrians as they help guide traffic and limit motorist movement on the roadway. The material, color, and layout (continuous, dashed, etc.) all communicate messages to the motorist which guide their movements. In some cases, this can also be accomplished with words and/or symbols on the roadway.

Refer to the , TxDOT’s , and TxDOT traffic standards for specific design requirements for pavement markings.
