As JonnyG and Hutch rightly says, this is very confusing...

It looks like Mrs paws is licenced to ride a full motor bike Category A although she has never done so and never taken a test on one (I don't think I'll mention this to her though!!!) :woohoo:
I can't really think this is right, but my motto is to leave sleeping dogs lie, so I'll not suggest she takes it up with the licencing people.
She did have a moped (49cc and with pedals) prior to passing her car test, but this may be bit of a red herring as I think mopeds and small scooters are covered by the basic car licence anyway (subject to various limitations)
The good new is as far as I'm concerned is that she (and me as well, post age 70) are licenced to tow a car caravan combo that doesn't limit her or me to only the smaller lighter models... although having said that our car caravan combo is pretty small anyway!
I decided to take a look at the .Gov website that deals with this sort of thing...... consequently I now need to have a lie down in a quiet darkened room, as I'm now suffering from a very sore head, practically square eyeballs and a strong belief that the good folks who are in charge of these sort of rules and regulations are part of some giant job creation scheme, that are committed to producing information and drafting and enacting/the passing of rules and legislation that is masterly in it's grasp of, and display of obfuscation, and practically guaranteed to be of no earthly use at all to a significant proportion of folks who are seeking enlightenment.
I just hope that Mrs paws doesn't read this as other wise she might be tempted to add to her shopping list a nice second hand Royal Enfield Constellation..... just the job for her, when popping down to the supermarket!
The important thing to remember though is very simple... it's just this:
Happy Caravanning!
Regards to all
