Experts say this summer has the potential to be even worse with British families returning from holiday caught up in the chaos.
Ukip MEP Steven Woolfe said: “The realities of Calais are still very real for the hauliers who travel through the port regularly. It is the UK’s gateway to the European continent and any continued disruption causes a great deal of uncertainty for hauliers and harms their economic activity.
“While officials have committed additional funding to increase the security of the port, including more fencing, this is simply a knee-jerk reaction and a short-term fix.
“As the summer moves closer and the weather gets better, a new influx of migrants into Calais should be expected, which will only exacerbate the problems we see today.”
Drivers can be fined up to £2,000 for every illegal immigrant found in their truck.
In 2013/14 1,625 penalties worth a total of £4.2million were issued and in 2014/15 3,321 fines worth £6.6million were handed out.
The FTA, which represents more than 15,000 members, has called for urgent action to tackle the problems, saying more needs to be done by the French and UK governments to protect people. Around 9,000 lorries a day – three-quarters of all road freight in and out of Britain – passes through Calais.
