Hi,
I've had my driving license for a few years now but only recently bought my first car. Whenever people mention in conversation, "The M11 was closed, super busy, etc. so had to go via the e.g. A14" I'm super confused as I have no idea what any of it means. Is there a quick way to get familiar with the major motorways/dual carriage ways etc.?
As I understand it, an "A" is a dual carriageway, whilst an "M" is a motorway.. that's all I seem to know.
I live near London by the way.
