Hi Colm,

Strictly speaking, category N1 refers to vehicles "designed and constructed for the carriage of goods and having a maximum mass not exceeding 3.5 tonnes.” Basically vans, but of course, there are now a number of large 4x4s (Jeep Grand Cherokee, Land Rover Discovery, Mitsubishi Pajero, Toyota Land Cruiser) that also slot into that category even if they retain seating for five.
