These signs and the typeface are my gold standard. I've traveled to dozens of countries, and I still think the British signage is the cleanest and clearest in the world.
Quite often temporary roadworks signage uses something "off brand" like Helvetica, and I actually want to deliberately break the temporary speed limit out of spite.
