BERLIN — German police say hundreds of cars and pedestrians are lining up at border crossings along the Czech-German border after Germany declared the Czech Republic a high risk area in the pandemic, meaning it requires proof a negative coronavirus test results before entry.

At the crossings in Waldmuenchen and Fuerth im Wald authorities said hundreds of cars lined up on the Czech side trying to get into Germany in the early morning hours. Further backup was expected during the day Monday.

Since Sunday, people from the Czech Republic need to show negative test results no older than 48 hours every time they enter Germany.

The Czechs who commute to work in neighboring Germany formed long lines at some border crossings, waiting for required tests on the coronavirus.

The Czechs were boosting the capacity of their testing site at the crossings and elsewhere to meet the growing demand.

Czech Prime Minister Andrej Babis was scheduled to discuss the situation with his Bavarian counterpart Markus Söder.

Other Czechs who don’t work in the neighboring country on a daily basis have to have a test but also need to isolate for 10 days if they travel to Germany.
