With temperatures getting low as well it could also make the de-icer crews use less effective.
When temps get really low, especially in higher elevations, crews have to switch to a salt and sand mix which helps prevent ice from forming, and gives more traction.
Even on treated roads there have been several reports of crashes and motorist sliding off the roads.
Police say one of the main reasons for crashes in this type of weather are drivers going too fast for the conditions.
They recommenced people slow down, leave space between the cars in front of them, and give themselves time to get where they're going.
