Handling short-term maintenance operations such as pavement patching or litter pick-up on rural roads

Texas DOT typically utilizes truck-mounted arrow panels when travel lanes are blocked for very short periods of time. In some cases, TxDOT also uses a special “Lane Blocked” sign on a vehicle running behind the caravan on the shoulder that shows a row of numbers corresponding to the number of lanes on the roadway, and an “X” below which of those lanes are closed (similar in concept to an overhead lane control signal array that might be used on an arterial or freeway).
