Driver location signs are signs placed every 500 metres (550 yd) along each side of English motorways, and some other major English roads, to provide information that will allow motorists to know their precise location. As of July 2009[update], roads in England, but not Scotland, Wales or Northern Ireland, have these signs. This information might be useful in the event of an emergency or breakdown. They were first introduced in 2003, and they complement distance marker posts (small roadside posts used for road maintenance and administrative purposes). Both types of sign display a unique location number. The number, although given without units, is the distance in kilometres from a designated datum location for the road, although signs meant for driver navigation are in miles.
