Haulage Permits and Trailer Registration Bill [HL]

Before the Minister responds, I will widen the question a little. My noble friend mentioned the example of a lorry starting in Dublin and going through the UK to the continent, and asked whether it needs a permit. That is why I tabled Amendment 14B, which we shall come on to in due course, to ask whether foreign trucks need a permit to enter the UK. Surely it does not make any difference whether it is delivering from Dublin to the UK or going through the UK to deliver to Paris, as it still needs the same licence. Is my assumption correct?
