In the U.K. it’s the vehicle that has the restricted speed limit. If it’s N1 registered and the other criteria apply such as over a certain weight then the speed limits will apply. My Grenadier will be used for my own private purposes ie.hauling logs out of the woods carrying tools etc plus commuting, but mainly for travelling. As far as I’m aware the restricted speed limits apply to me , but other than that I will drive as a normal car.I may drive my N1 Ute here in Germany like any other 'normal' car since it is not used commercially.
I wonder how the table linked above applies to me if I drive my German N1 in England?
I assume this applies to you also if your vehicle is N1 registered. Hope this helps.
