Mr. Seamus Scallan:

It is 9-1-9.

From the time the transport leaves Ireland, there are 19 hours to feed the calves. The driver can drive for nine hours, stop for one hour and drive for another nine hours. It is known as 9-1-9. The ferry journey takes 16 or 17 hours and when the transport leaves the ferry, the driver must go to the nearest point to feed the calves. Wherever he drives in Europe he must apply the 9-1-9 rule. If he does not reach the destination in 19 hours, he must stop for 12 hours to rest and feed the calves before continuing.
