Hi,
I'm planning a 10-day car trip arriving from the US in Zurich, renting a car, drive the same day to Strausburg, France and from there drive thru the smalls towns to Colmar. From Colmar I want to drive thru Lausanne, Chamonix, Interlaken and drive back to Zurich.
Are there any issues in driving a rental car from Switzerland to France?
Is late April safe (snow, icing conditions) to drive thru the Alps?
Thank you.
