Here they are now spraying the roads with a calcium chloride brine. It does a great job of clearing the ice and snow from the roads. Talk to any heavy truck mechanic about what this is doing to vehicles. This stuff gets past the weather pack electrical connections and corrodes the terminals and wire. Brake lines are rotting out if not undercoated regularly. If they are doing a brake job on a big rig, they make sure they don't disturb anything electrical or there is a good chance that something electrical won't be working when they are done. The stuff needs to be banned.
