Just to update. Took a lesson on the EB.

The instructor informed me and after reading it on the RSA website, that from 4 April 2011 any person applying for a provisional licence (learner permit) will have to take out 12 compulsory driving lessons (€€€€ !!!) No, the lessons you did for B don't count, EB is separate

Simply, get your prov EB before March if your towing a trailer and save €'s
