A unique traffic light
We’ve all used to seeing traffic lights with green, yellow and red color. This unique traffic light has an hourglass illustration instead. When the time runs out, you should stop. We guess it changes colors also, red for stop, yellow for be prepared. It’s a nice way to let the drivers know that they can turn off their engines. That will save their fuel and reduce air pollution.
There’s only one issue with this. Are the pedestrians’ traffic lights made the same way? People with impaired vision and guide dogs can’t function properly with this type of traffic light. Dogs can’t distinguish color on the traffic lights. They are trained to stop or go depending on the position of the light, up or down.
