Speed Limit Board / Traffic sign board

Speed Limit Board
Speed Limit Board

There are two layers on this board. The top one shows the restricted speed on sunny day, and the bottom one shows the speed when rainy. The material of the top layer will become transparent after absorbs water. And then the restriction speed number on the bottom one will show up. When it turns sunny, the water evaporates out and the speed number on the top layer will appear again. In this way, the board can show different restricted speed automatically and naturally according to the weather.
