Driving lyon to carcassonne late december

We are planning to drive from lyon to either carcassonne 27/12.
Not sure if this is a good idea bit it looks like only a 4.5 hr drive.
We leave interlaken or chamonix 26/12 and need to eventually be in girona spain 29/12.

Have driven in europe before but different time of yr

Thought we would drive instead of train as change from train on our 7 wk trip.

Any advice appreciated.
