Slippery When Wet Sign
The road surface may be particularly slick or slippery when wet, so be careful here.
Low-poly, 128×128 textures, and shares a common specular map and mesh with my newer (and upcoming) road sign assets if you use the Loading Screen Mod.
All my signs are props, so you need to use More Beautification mod to place them. They show up in the general props category (the park bench icon).
