I live in Romania, where the government deals with COVID-19 by passing temporary laws. My questions however, is with regards to the EU as a whole and any convention that may apply to cross-boarder travel during the COVID-19 pandemic. So it might be a law question on topic for this site. My second choice is travel.SE.
Specifically, I have to travel from Romania to the Netherlands over land (by car), which involves 4 boarder crossings. My question would explain why I believe my reasons count as "urgency" and documentation I intend to produce for relevant authorities.
The question comes down to: "Am I allowed to travel from Romania to the Netherlands?"
