The Met Office has issued two yellow weather warnings across North Yorkshire for snow and ice as harsher weather conditions are expected.
A yellow warning for ice came into force at 3pm this afternoon and is expected to last until 11am tomorrow morning.
Forecasters say ice is expected to readily form overnight as rain and snow clears.
In a Facebook post, North Yorkshire County Council said: "In the Ryedale, Scarborough, and Whitby areas all routes are passable with care.
"Our Highway Officers and gritter drivers are reporting that the conditions are very icy and there is still frozen snow in the centre of the carriageway on many routes which is proving difficult to plough.
"Our teams are being joined by our farming contractors who are working on our Priority Two routes.
"Please take care and only travel if necessary."
A yellow weather warning for snow comes into force at 5am on Wednesday and lasts until 9pm on Thursday.
