CORRECTION: in the commentary of this video I mistakenly misread ‘A3094 Livestock Market’ as ‘Laverstock Market’. This is an example of ‘seeing what you expect to see’ - Laverstock being another area of Salisbury. When Margaret Calvert & Jock Kinneir designed our current road sign style, launched on 1st January 1965, they referred to the report ‘Mile-a-minute typography’, and moved from all capital letters to a combination of upper & lower case lettering to help our brains see the ‘shape‘ of the word as well as its letters for quicker recognition. As this example highlights, it doesn’t always work for similar words! If in any situation you find that you have misread a sign and are in the wrong lane, continue in that lane and correct your error later unless it is safe to make a lane change. ‘Getting slightly lost’ will not fail a driving test, a hasty dangerous lane change will!
