Pavement markings provide important information to road users. There are several sources of information that TxDOT engineers, designers, and inspectors can use to obtain the information needed to effectively select, specify, and inspect markings. This handbook attempts to tie all of that information together, supplementing it with additional information to help TxDOT staff involved with pavement markings. The handbook was developed as a single source of information for anyone involved with pavement markings in Texas.
