More than 235,000 hauliers have had a covid-19 test, according to the UK government.
The testing programme for truck drivers was introduced in December by the French government.
As a consequence, drivers have since been required to have proof of a negative coronavirus test before entering the EU.
In response, 37 UK sites were established to enable drivers to get tested before arriving at UK ports.
Subsequently, major delays were averted as hauliers followed the advice and got tests up and down the country.
The French government has recently changed testing arrangements for hauliers traveling from the UK.
French authorities are accepting test certificates from Ireland for hauliers using UK ports. Hauliers who spend under 48 hours in the UK won’t need a covid-19 test.
However, the UK government is still reminding hauliers who do need a test to get one early in their journey.
“It’s encouraging to see traffic continuing to run smoothly through Kent,” said transport minister Rachel Maclean.
“While we are making good progress, it is vital that hauliers keep making use of the 37 advice sites around the country,” she added.
Meanwhile, the armed forces – who conducted more than 128,000 tests – have stepped back from the testing effort.
Colonel Ian Adkins, deputy commander of the Joint Military Command, South East, paid tribute to the individuals involved.
“The initial backlog of thousands of vehicles was cleared within three days,” he said. “The focus then switched to maintaining a smooth flow of hauliers through Kent.”
