Town of Dickinson, NY (WBNG Binghamton) Many of the local school districts bused their students home early Wednesday, before the worst weather was expected to hit.
But one of the busiest times of the day for commuters was also when the temperatures were expected to drop below freezing.
Black Ice is almost impossible to see while driving, and it's almost impossible to control a car if drivers come across the ice.
The Broome County Sheriff said people on the roads should take it slow to get to their destination safely.
"Ice you have no control, I mean snow you have some control of your vehicle," said (R) Sheriff David Harder, "Once you hit an ice patch you're gone. You're spinning; you're going wherever you're going to go. That's what makes it so dangerous."
Sheriff Harder says they will have more patrol cars on the road tonight and they're already preparing for Thursday morning's commute.
He said that could possibly be the worst time for accidents because drivers might not give themselves the extra time needed to drive slowly into work.
