I just saw a car that was rusted really bad. Ruined with rust. Why do they spread salt on the roads?

It’s not actually salt, it’s road salt. Salt helps to melt ice and snow, which makes the roads safe. The salt is usually only put on roads during the winter.

Oh, wow. Well, ice and snow form on the roads and the salt helps them melt faster. Also it allows you to make sure you don’t slip on ice.
