Covid related - driving trip - entering Switzerland

Transportation, Travel and Trips
1
I plan on a long driving trip soon.

One that will take me from Switzerland through Germany, through Austria, into Slovenia and finally stay in Croatia.

I will then return to Switzerland from the same route.

I am fully vaccinated

At the Swiss border, will I need to provide a Covid (PCR or similar) test?

If I read the websites correctly - Germany, Austria, Slovenia and Croatia do NOT need a Covid test to enter.

If you have Swiss plates on your car, I doubt you will even be stopped. But take all the documents your have with you in case. Especially your vaccination cert/App...

You need a test to enter.

It's confusing to me though. Here's the image in English (link because image is huge):

This seems to imply that if you're Swiss and went on holiday in Germany, you need an entry form and a test to come back. But if you're German and want to enter Switzerland you don't need an entry form or a test.

That makes no sense at all.

Only commuters and people living in certain regions. Anybody else needs the test?

I know Austria you either need a PCR or have Booster to stay, but if you are transiting the country then this is not needed. But obviously check each countries websites as the rules are forever changing.....

Coming back into Switzerland you need to do a test after you come back, but not to enter, but again check the websites and the goal posts are always moving. When you fill out a Swiss locator form (which you must do before returning) this is registered and you get messages to remind you... and a link to upload your test result... (had this after returning from Italy end of last year)

Re-open EU is a good site for getting a travel overview country by country, although I would always also check the individual countries' sites.

Thank you everyone for your help.

I am continuing to research and will take your comments.

The only thing that surprises me - each of the countries have a similar approach - but Switzerland does not follow them.

I know, I know - Switzerland is different ---- I just assumed it would not have been different.
