they ask you what the current speed limit is, and how you know/give reasoning..
so 30mph, built up area, no reminders.
40mph semi built up area but reminders in place, and still street lights etc..
50mph = restrited national because of traffic badspots/ bad surface quality, the odd dodgy corner/junctions on corners etc.
just by driving at random speeds doesn't proove you know what the limit is:nutter:
