Will salt keep cars from sliding off snowy streets when its cold?

Answer 1

A straightforward salt product does very little to help with traction - its purpose is to melt ice. A lot of the time, you'll have anti-skid in use, with is typically something like 83% sand, 17% solar salt... the sand is to help with traction.

Answer 2

Nope. Salt is used to help improve traction, but will not totally prevent a car from sliding off the road.

Answer 3

The colder the road temp is the less effective the salt becomes.
