CENTRAL POINT, Ore.-Even if there is no rain or snow, roads can still form black ice due to freezing fog.
The Rogue Valley has seen dense fog for the past couple of days, especially Monday night.
NewsWatch 12 talked with Oregon State Police to find out what you can be doing to prep your car for slick roads.
"Generally during the winter months of driving, even past the holidays is people need to be prepared for inclement weather, this is something we talk about every year, make sure when you're going on a trip or somewhere that you have a full tank of gas, making sure that your tires are in good shape," says Sergeant Jeff Proulx.
Chains may also be required for some roads.
He also told me that car crashes generally increase during the winter months.
Proulx says it's important to keep water, snacks, and a blanket in your car too incase of road closures or long waits due to a car accident.
