On my provisional licence it says i can ride category 'A' from 31.01.2013 (when I'm 17). Category 'AM','A1' and 'A2' (the new category's from 13.01.13) are left blank. I'm riding a moped at the moment. Does this mean I can still go straight to my big bike test (33bhp for 2 years) when I'm 17 even though i'll be taking my test after the law changes?
