Darren Barefoot sez, "Apparently sat-nav systems are hazardous to the health of British (and visiting) drivers:"

Vale of Glamorgan Council in South Wales is the first in the UK to use visual signs warning drivers not to believe sat-nav advice after once peaceful villages were reduced to bedlam when heavy-goods lorries got stuck in tiny country lanes.

Now a sign aimed largely at foreign drivers has been put up on the outskirts of the village of St Hilary.

"The proliferation of satellite navigation aids used in heavy goods vehicles, and their over-reliance, especially by overseas drivers, has presented itself as a problem within the Vale of Glamorgan," a spokesman for the council's highways department said.
