THIS official sign on the A4 in Wiltshire has entertained drivers for its peculiar spellings.The mystifying sign spelling out a route for "unsitable" traffic down a "diversionary" route has appeared at the top of Hartham Lane, off the A4 at Pickwick.

Wiltshire Council has been carrying out roadworks on the nearby Cross Keys junction for some weeks but it is not yet known who is responsible for the sign's wording.
