Truck-mounted attenuators; certain vehicles equipped with amber and green warning lights.

This legislation authorizes the use of combined amber and green warning lights on truck-mounted attenuators—the safety barriers attached to the rear of construction and maintenance vehicles. Currently, these vehicles rely on amber lights to alert motorists of their presence in work zones. By adding green lights, which studies suggest are more effective at grabbing driver attention and reducing speed, the state aims to increase visibility and improve safety for road crews operating on Arlington’s busy highways and arterial streets. This update brings Virginia in line with other states that have adopted dual-color lighting systems to mitigate the frequency of high-speed collisions with protective vehicles, ultimately creating a safer working environment for maintenance personnel and reducing potential traffic disruptions caused by site accidents.
