These are pretty common in Sweden because, if properly modified, they can be driven by a 15 year old as a tractor. While 18 years old and a more complete drivers license is required for a regular car. And obviously because Volvo is swedish, that is the most common model to modify. One of the required modifications is to remove the rear seat so that it is no longer built for personell transport. It should also not be possible to drive faster than 30km/h.
