Welcome to the family... I now have a 44 No2 mk2*. prior to that I had a 42 Mk1*
as for your question, you need to know that answer for your test.
if the track laying vehicle has resilient material (read that as rubber) on the tracks or its road wheels, and is fitted with suspension, the speed limit is 20mph. if it has none of the above it is 5mph.
that is for UK.
I would never advocate someone take a carrier onto the road if they have no experience with tracked vehicles.
carriers particularly can be twitchy
get some images posted up buddy
