My tip would be don't travel unless necessary, many jobs allow working from home in the post pandemic era.
If you do venture out make sure the car is fully defrosted and all windows clear, also be wary of using your screenwash which can instantly freeze in cold conditions.
I have a recollection of driving on black ice on a dual carriageway, car in front spun hit the kerb and then rolled over three times (fortunately no one was injured). I stopped and got out of the car, immediately falling on my arse it was so slippy.
