Hauliers boarding a ferry to France are required to have a negative Covid-19 test from today.
It's after the French government introduced new requirements for entry into the country.
Antigen testing centres have been set up at Dublin Airport and Gorey in Wexford, with others to follow.
Truck drivers fear the requirement could result in missing ferry sailings.
However, Junior Transport Minister Hildegarde Naughton, says pre-booking a test will avoid difficulties.
