Here's a weird thing..... It seems I already have a
provisional license to tow a trailer..... so I think I'm right in saying that if I slap some L-plates on and take Mrs Womble or Bloomer with me (or frankly any other old fart, regardless of trailer experience
) then I'm good to go without sitting the additional test!
Ain't the law a funny thing at times!?
EDIT: ^ Apparently that's no longer the case, and there are new laws as to who can supervise a learner with a trailer. As a result,
I ended up doing my B+E test, and posted some notes on how it went on this thread. Cheers!
