Travel and covid: rules and restrictions

To ensure safe travel, by road, rail, plane or ship during the coronavirus pandemic, the EU has made available a traffic-light system classifying EU countries (EU 27 + Iceland, Liechtenstein, Norway and Switzerland) according to COVID infection rates.  You can also find information on entry requirements as well as any restrictions and special rules in place (for example on quarantine and testing).  As some countries may have stricter rules, check the specific measures that apply to the country you are planning to visit or transit.
