Limited / Limited


While lots of traffic accidents are caused by wet or icy ground conditions, LIMITED is the material that can make road sign sensitive to weather.
LIMITED can be printed or as a sticker. The material of the top layer will become transparent after absorbing water, then the restriction speed number on the original plate will show up. When it becomes sunny, the water evaporates out and the speed number on the top layer will appear again. When it come to cold weather, it can liquefy snow(melt agent) and keep transparent until ice sublimated. In this way, the board can show different restricted speed automatically according to the weather.
