Highway Signs Need Cleaning Too. 🚧💦Highway signs are constantly exposed to road dust, vehicle exhaust, mud, bird droppings, insects, salt, and other contaminants. Over time, this buildup can affect sign visibility and nighttime retro-reflectivity.But cleaning elevated and overhead signs comes with its own challenges:Working at heightTraffic managementDifficult-to-reach surfacesLarge equipment requirementsWater and pressure managementLimited roadside working spaceCleaning drones provide an additional option for suitable highway sign cleaning applications. Operated from the ground, they can reach elevated signs and other difficult-to-access surfaces while reducing the need for workers to directly approach certain high-altitude areas.However, drones are not a universal replacement for conventional equipment.
