DRIVING ALERT: Road salt doesn't work in extreme cold

(WTOL) - A series of fender benders slowed down the morning rush hour drive. Black ice formed on roadways. It's likely to happen again over the next couple of days.

There wasn't much the Ohio Department of Transportation (O-DOT) could do about it.  Crews tell News 11 roads are impossible to treat when the temperature plunges to five degrees. The problem is that salt needs moisture to work. If you put dry salt on ice, nothing happens.

Salt treated with calcium chloride in cold weather sometimes works, but only if the sun is out.

Temperatures Thursday night are expected to dip to 15 degrees below zero. O-DOT will spread a grit solution that's a 50/50 mix of salt and stone and hope it's effective.

In the meantime, they urge all drivers to slow down and be cautious on roadways.
