“As you’re driving along, you see a road sign ahead. You can see as you get closer that it’s rectangular. There are three colours of rectangular signs and they tend to be for information.
The first one is a little bit sneaky because on motorways, a blue background sign is a direction sign, but elsewhere it’s an information sign. So, if you’re on a motorway, you would see a blue rectangular sign for directions and a blue rectangular sign elsewhere is giving you information.
On a green background, these are direction routes for non-motorway routes. So, on an A-class dual carriageway primary route, you would see a rectangle with a green middle and a direction sign within it telling you where to go to local towns, that sort of thing.
The bottom rectangle is white, you would find these on non-primary routes, some A roads B roads and country roads and that’s giving you information and there may be other signs around it as well. So that’s information and direction signs on non-primary routes.”
