The Department of Transportation says studies show that the green lights are more easily detected by the human eye than other colors. The green lights, along with white strobes, will be added to the existing amber lights to make the plow trucks easier for motorists to see.
Officials hope it will cut down on rear-end collisions with the plows. Ohio has far more collisions with snow-removal trucks than neighboring states.
For much of October, state workers have conducted 150-point inspections and other tests to ensure snow-removal equipment is ready to go.
