The Irish Road Haulage Association says the Calais migrant crisis is having a detrimental affect on exports.
The body is calling on the Government to join in efforts to bring the situation under control.
It says 90% of Irish exports travel through the French port and drivers are fearful for their own safety as the face the hundreds of refugees gathered there.
Eoin Gavin, European representative for the IRHA, describes the scenes in Calais: "I was in Calais myself on the 4th, 5th of July, I was going to Germany. We sailed into Dunkirk, we came back by Calais and the situation there would remind you of crowds of people coming out of Croke Park on All-Ireland day.
"It's very intimidating for drivers, we have a situation where we have a driver shortage in Ireland currently, and we now have international drivers telling us they don't want to go out to Europe anymore."
