Perhaps I could speak again, because I have been reflecting on what was said. There is another way to deal with this, which is why I intervene:
we have gross weight figures. If we had a few more court cases about people using trailers that exceeded the gross weight, that might send out a message “pour encourager les autres” to comply with the law. That is one way to deal with it, along with the lock and chain. I am talking about the smaller trailers, which are worrying me, and which comprise the great volume of trailers.
I come to my second point. I do not have a trailer at the moment but until a few years ago I did. It was a small trailer, probably half the size of one of these desk tops here. We used it once or twice a year. If you are registering it, MoT-ing and all that, that is quite an expense if you use your trailer very rarely. As I say, unless they are in business, people do not drive around with their trailers all the time. They are for occasional use.
There are circumstances in which an MoT could be applied, and that is when a trailer has a brake. If it has a brake, it really is a different piece of machinery. All that most trailers have is a wire that connects the vehicle to the trailer to feed the lights—nothing more. However, where you have a trailer with a brake, my noble friend’s case holds water that there might well need to be some sort of system. I imagine that the two-tonne trailer that my noble friend referred to had a brake; I do not know.
