For-hire vehicle drivers are giving their rooftop billboards one last ride this week. The money-making signs, which have been the subject of a long-running legal battle, have been ordered off of cars, to the dismay of a small group of drivers that had them installed.

The Independent Drivers Guild, which represents Uber and Lyft drivers, is still hoping to sway the Taxi and Limousine Commission, which recently reinstated a longtime ban on advertising by for-hire vehicles.

The TLC’s action came after a federal appeals court ruling last month reversed a lower court decision that had gone against the ban. Drivers have until Aug. 31 to take down the digital signs.

The city has opposed interior, video advertising systems on the basis that they would pose an annoyance to passengers. It considers the exterior advertising—rooftop digital billboards—a form of visual clutter, a position in line with a recently enacted state law that has banned floating billboards from New York waterways.

The Drivers Guild argues that the ban hurts drivers, whom it says are still struggling despite a minimum wage law and other regulations aimed at improving their finances.
