There are laws in many cities around the country prohibiting heavy trucks (classified as having a gross weight over 6000 lbs) from driving on residential streets. They are designed to keep the trucks on larger roads where they are less of a danger and annoyance. It turns out that many SUVs are also illegal to drive in residential areas. Most large SUVs are designed intentionally to be over the 6000 lb line because that’s also the the point where they become a tax write-off commonly employed by the wealthy. Funny twist, eh?
