This all happened when they revised the licence cats. They dropped the gvw of a car license to 3500kg and made in affect the 7500kg an lgv license. It all causes havoc here as some of the younger drivers are not aware of some of these rules. There is also talk of trailer mot`s coming in so any home grown device may need some kind of type approval in the future. The same is happening for this year about a tow bar needing to be type approved, goodbye home grown tow bar devises.
