Even after san trucks come through, drivers still need to be extra careful. The day started with freezing rain, but by the afternoon there were flurries and some sleet.
"What's not frozen today, I think is going to freeze tonight," says Danny Stephenson, "it's going get slick."
The Texas Department of Transportation poured sand on the bridges and main roads, the best thing to do is avoid driving all together.
"I think the roads are going to get worse, we're getting just a little bit of that mist, and temperatures are dropping," says Stephenson.
By nightfall, the roads were covered in a blanket of white sleet. Even with dangerous road conditions many drivers are still out on the road.
"It's not that bad," says Kerry Belieu, another driver, "but you always have to worry about the other drivers."
May school districts acorss the Big Country canceled school for the kids, but for the grown-ups who need to work, sometimes they don't have a choice.
"I don't want to go to work," says Belieu, "but I have to."
"I'd probably stay off if I could help it," says Stephenson.
It's important for all drivers to proceed with caution, allow yourself more room to stop, make sure your lights are working, and windows are clean. Bear in mind that the speed limit may say it's okay to drive at 40 miles per hour, but with black ice on the roads, it's better to keep a slow crawl.
