A direction sign, more fully defined as a direction, position, or indication sign by the Vienna Convention on Road Signs and Signals, is any road sign used primarily to give information about the location of either the driver or possible destinations, and are considered a subset of the informative signs group. Direction signs are far more varied internationally than other classes of sign, as the Vienna Convention does not specify sizes, colours, symbols or positions of such signs.
Direction signs are the oldest type of road sign; Plutarch writes about milestones being placed in the 3rd century BC, while some fingerposts in the United Kingdom date back to at least the 1690s. However, it was not until the invention of the motor car at the turn of the 20th century that modern direction signs, with fewer words and clear design, allowing them to be read at speed, evolved.
