Does salt not work in melting snow and ice?

According to Yahoo answers, if it's 10 degrees or lower, it doesn't work. However, if you get some of these guys on the road, it doesn't matter.

My understanding is that salt's effectiveness is significantly reduced at 15 to 20 degrees or below, and that it's absolutely useless at -5 or so.

Water that has been fully saturated with salt will freeze at about -6 degrees. But since that's a lot of salt, HC's and mcpapp's numbers are more reasonable.

It's probably calcium chloride. It can lower the freezing point of water down to -52 degrees, depending on it's density. BTW, calcium cholride is a salt. But it has different properties of normal road salt, which is sodium chloride.
