The Direct Gov website gives lots of useful advice and help on starting to drive :-

This link leads to an online copy of the Highway code - the rules and regulations for all road users. Reading this is always an important (if not exciting!) starting point for new drivers and good preparation for the Theory test:-

Here you can read through all of the current questions :-
Show Me - Tell Me Questions - From 4th December 2017
