Joseph B. Reid >On a visit to Britain in 1985 I noticed obscure little distance signs >along the motorways every 100 metres.
They are called 'marker posts'. www.btminternational.co.uk/motorway.htm www.roadsafety.co.uk/motorway.html They are individually numbered. They have a telephone symbol and an arrow pointing to the nearest free emergency telephone (it should be within 750 metres). >Britain still has not converted speed limits or official distance signs to metric. British road engineering is 100% metric, but the faces of signs display non-metric values. There are exceptions: 1. weight limit signs are metric only 2. new height and width signs are dual unit www.highwaycode.gov.uk/signs04.shtml British sub-mile distances are in yards. US sub-mile distances are in feet. That makes it difficult for British and US drivers to 'feel' distances in the other country. Of course, converting yards to metres will be easier for drivers than converting from feet to metres.
