French company Eurovia is reported to be developing a kind of thermo sensitive varnish that can change color as the temperature changes. The application Eurovia is looking for is road markings that can warn drivers when the surface temperature on the road comes close to freezing. When temperatures rise again, the varnish resumes its original color. If they can get this to work at a cost that allows it to be implemented on a wide scale, the safety implications are of course obvious. Every driver does not automatically consider bridges and low ground as potential ice patches.brbr
