Limburg, Overijssel, Drenthe and Friesland have so far sprung from the dance, but Belgium also advises against traveling to these provinces from Friday afternoon. Those who have stayed there for two days or more must undergo a corona test and quarantine upon arrival in Belgium. That is difficult for Limburg, which shares a large part of the border and a lot of border traffic with Belgium.
Border province of Zeeland is currently avoiding the red travel advice. Travelers from that province are only recommended a test and quarantine.
