Some Schengen countries have installed border checks "because of covid 19" and some had border checks even before that, often only randomly. I also heard that you're generally required to enter a country through a port of entry. However, I cannot find any such rule regarding Schengen. Therefore my question is: When crossing to such a country as a citizen of a Schengen country, are you required to pass in a way that bears some likelihood of getting checked?
Suppose that you are carrying your national ID / passport as well as any covid certificates necessary and are carrying no goods that would need to be declared. Are you allowed to actively avoid border checks? E.g.:
- Crossing by car using a dirt road with no checks.
- Walking across the border in a forest where there obviously will be no border checks.
- Putting your rubber boots to good use and walking through a small river.
