I'm looking up van insurance options for going forward, from what I've been reading it's generally the smaller the van the cheaper the cost, then if it's in a yard it's cheaper and if drivers are over 25 etc. But going from one van/driver to two or three vans with 4 drivers should I be expecting it to cost three times as much on a multi van policy. I know there's so many variables but need to ask to get an idea.
